How to compress images, audio, video files on Android

Modern phones are capable of taking high-resolution photos, which is a disadvantage for some users. Previously, smartphones took pictures of 500-1000 KB in size, but now the situation has changed for the better. It will not be difficult to find a device that creates images of 3 megabytes or more in size. Such pictures take up a lot of memory, so users are interested in how to reduce the size of photos on an Android phone. Let's take a closer look at the services that allow you to do this quickly and for free.

What is compression?

Any information, whether it is presented in text, graphics, sound or other methods, occupies a certain part of the storage, whose 100% filling leads to a decrease in the speed of the system and the inability to save new data. The most “radical” options are: deleting files as soon as they are no longer needed, or purchasing an external MicroSD storage, for which there may simply not be a slot left due to the inserted SIM card. By the way, if you have an external drive in your phone, you can find out how to install applications on Android directly to an SD card .
A more convenient way to deal with space overflow is represented by compression. This word means reducing the size of files by reducing their quality, which, despite the rather long description, is not difficult even for ordinary users. Another example of using this method is sending images through online services where inappropriate limits are set on the “weight” of pictures, as well as transferring pictures over a limited mobile connection.

Why change screen settings?

There are 2 main reasons:

1. Reducing the resolution reduces the load on the hardware - the fps in games increases, the battery drains slower, but the image becomes less clear.
2. Increase the pixel density and font size - the picture will become richer, but the battery will start to drain faster due to the increased load.

Note! You should not increase the resolution on smartphones with budget chipsets. Without power reserves, the device will heat up and lose performance.

Compression methods on Android phones

By choosing the right method for carrying out the operation, you can literally optimize the image - it will not only get a smaller size, but also practically not lose in quality, so that neither you nor the recipient of the message will notice any shortcomings.

Via Android apps

Photo Resizer HD

The key advantage of the utility, which is the reason for its placement in the first place in this material, is support for a wide range of devices - among the compatible ones are system versions from 2.3.3 inclusive. The simple process of use is also considered an advantage, not suppressed by the lack of Russian localization. The instructions are presented in just a few steps:

1. On the start screen, select the “Gallery” option, then specify the path to the image you want to make changes to;

2. Using the buttons on the bottom panel, crop the picture or specify its desired size. In the first case, you can set the aspect ratio, either independently or using the options offered by the developers;

3. Click on the checkbox and apply other corrections if desired - JPEG quality level, corner smoothing, saving or clearing metadata.

It supports working with multiple images simultaneously, which can significantly save time. You can independently choose where the result will be saved - to external or internal storage. The program is distributed free of charge on the Play Market, but it contains advertisements. The word “HD” indicates the availability of working with high-definition images, saved by almost all cameras in phones.

Photoczip

The interface of this application is also simple - when you first launch it, you will see two sections: “Album” and “Optimized”. The first contains a list of all recently downloaded images, and the second - those already optimized using the utility. The lower right corner contains a camera image, tapping on which opens the shooting program. The picture taken through it will immediately appear in the photo editor window.

Follow these steps:

1. Specify which picture should be processed; for group selection, long tap on the name;

2. Select "Compress" and wait a couple of seconds.

Based on the compression results, you can familiarize yourself with the file properties and evaluate the result by comparing the sizes of the original and enhanced images. Software functions are available to Android users older than 4.4. For greater convenience, it is recommended to install the widget on your desktop - then you will be able to take small pictures “without unnecessary movements.”

Photo Compress

Similar to the utilities described above, this one also has a simple interface that provides a short procedure - by completing such a small number of steps, you can optimize the file for sending somewhere or to save space.

Follow these points:

1. During installation, provide the permissions requested by the program. If you are using new versions of Android, access will be required after the first launch as necessary;

2. Select the photo source between two options: “Gallery” (already saved pictures) and “Camera” (create a new photo). The third point is used to work with several pictures at the same time;
3. Carry out the necessary actions to reduce the quality, resize and cut out interfering parts;
4. Save the image with all your changes.

Files created using Photo Compress are saved in a directory with the same name, which allows easy navigation through the generated results.

Bulk Image Compressor

Based on the name of the utility, it becomes clear that it is designed to work with several pictures at the same time, but nothing prevents you from using it to change one image. There is no Russian-language version, but this does not interfere with the use of the program, provided by an intuitive interface. You need to do the following:

1. Tap the button with the plus icon at the bottom of the screen;

2. Select the image you want to reduce in size. You can also use images located on your Google Drive, several gigabytes of which are available to every Android user;

3. The progress bar will indicate the progress of the process. Once it reaches the maximum, you can close the application.

The files will appear in a folder with the same name as the program.

Through online services

The options listed below are less time-consuming than the above-mentioned methods and are especially relevant when there is a small amount of free space in the storage. There is no need to download any software, just open the appropriate service in the browser, which also ensures cross-platform functionality - you can practically forget about problems with incompatible versions of Android.

iLove IMG

The service is available at https://www.iloveimg.com/compress-image. The above link “meets” users with a minimalistic design, where a brief description of the resource and file download buttons are visible. There are several of them, since in addition to the usual option for sending pictures, there is compatibility with pictures located in Google Drive and Dropbox.

The instructions look like this:

1. Tap the download button and select a file from the gallery. If the system offers alternative sources of images (for example, a camera), then nothing prevents you from using a more suitable method at your discretion;

2. Click on “Compress Images” and wait until the procedure is completed. As a result, it will be displayed how many times the “weight” of the picture has decreased.

If you wish, you can make any changes yourself using the buttons for: cropping, controlling expansion, converting to JPG, rotating, adding a watermark.

Image Compressor

We are talking about the Image Compressor service - imagecompressor.com/ru/. This site is available in Russian, which is a relief even without this simple interface. All you have to do is follow the following instructions:

1. When the page loads, click “Load” and indicate which image should be optimized;

2. Use the slider to set the quality level. The lower it is, the smaller the photo size, but the less legible its contents;

3. Click "Save" and go to the "Downloads" folder where the image will be located.

When using landscape orientation, the screen is divided into two parts, allowing you to compare the modified version in real time. The first one contains the original image, the second one contains the updated one.

Compress JPEG

The Compress JPEG service is available at compressjpeg.com/ru/. The scope of work of this utility becomes clear from its name - it works with .jpeg, .jpg files, whose advantage at the time of its appearance was its extremely small volumes. Now the leader in this plan is WebP, developed by Google and not supported by older browsers. The functionality is not limited to this format, since you can also select PNG, PDF, SVG and GIF.

The instructions look like this and apply not only to smartphones, but also to computers:

1. Once on the page at the address above, select "Download" and indicate which file you want to process. Drag-n-Drop is supported, which is relevant when using the stationary version;

2. Please wait while the service processes your request. Once it completes, the “Download” button will unlock. You can also optimize multiple images by clicking the Upload button again. Then for mass download you will need to tap on “Download all”.

Based on the information provided on the website, pictures are stored for one hour. This means that you will need to save them for this period, or you will have to do everything all over again, which, although simple, takes time.

Built-in Android tools

It is not possible to reduce the size of a photo by compressing it without using third-party software, but there is another method of improving the “weight” of a picture, represented by cropping. Everything is extremely simple - just follow the steps listed below in the correct sequence:

1. Open the “Gallery” application, tap on the desired photo in the list that appears;

2. Go to the editing menu by clicking on the pencil in the lower left corner;

3. Select the “Crop” option;

4. Using the dots along the edges of the screen, set the desired image size. All elements that are not inside the frames will disappear;

5. Select “Save”, after which a copy of the picture will be in your storage.

The integrated editor has been present in Android since version 4.0. Its changes in future releases of the operating system affected the design and additional functionality; the principle of working with the cropping function remains the same.

If the ultimate goal is to free up space on Google Drive, which is limited, then you can purchase a paid subscription or in the web version click on “Free up space,” which will lead to the deletion of similar images. Moreover, the Google Photos program itself sends notifications when it detects a lot of identical pictures, and tapping on it will take you to the control panel for freeing up memory settings. Sometimes a problem arises when the memory on Android is full, although there is nothing there .

Alternative methods

If for some reason you cannot use the methods discussed above, you should pay attention to the options described in this section. Despite the seeming strangeness at first glance, the methods below are effective.

Send via WhatsApp or VKontakte

To save disk space, even the “giants” of the virtual sphere use compression algorithms. For example, in the case of VKontakte you will need:

1. Launch the application;
2. Tap on the item “What’s new with you?”;

3. Click on the icon marked in the screenshot and select a picture;

4. Publish a post by clicking on the checkmark in the upper right corner;

5. Save the image by clicking on it and then selecting “Download”.

A similar situation exists with WhatsApp , however, since it is a messenger, you will need to forward the image to someone. You can even do it for yourself - for example, an account registered on a second SIM card. After downloading the image to your device, you can delete it from the third-party service.

Archive to RAR

RAR for Android

Despite the low prevalence of archives on mobile devices compared to desktop devices, Android still has programs that allow you to compress files of any type. One of them is the freely available RAR utility, made by the same company as the popular WinRAR on Windows. The scope of this application is wide and covers more than 15 formats, including .rar, .zip, .tar and the like.

The following are step-by-step steps for working with the program:

1. By launching the application, you will see the files located on your gadget. Find relevant images and other content that you want to reduce in size, then mark the content in the checkboxes on the right side of the screen. Tap on the picture with the “+” symbol on the top panel;

2. Select the desired format between three options, set a name and, if desired, a password. Apply the changes by clicking "Ok".

As a result, the desired archive will appear in the device’s memory, and to send the compressed image you will need to send a .zip or .rar file (depending on the one selected).

ZArchiver

The program also has a simple interface that results in easy-to-understand instructions:

1. Select a picture to archive. You can include several files in it by long tapping on one element and then simply clicking on the names of the others;

2. In the menu that opens with “three dots” at the top right, select “Create archive”;

3. Enter the name, compression level, password and additional parameters, then tap “Ok”.

The key advantage of this program compared to the previous one is the more detailed configuration of the final file and support for the 7z format, which is one of the best in terms of reducing the “weight” of content.

LCD Density Modder Pro

The only app of its kind that allows you to change the DPI (pixels per square inch) value. By decreasing this number, the size of everything on the screen (pictures, icons, font, etc.) increases. It is ideal not only for those who want to change the size for convenience, but also for people with vision problems. After installing the application on your smartphone/tablet, you must:

• in the settings, select the desired DPI number;
• confirm your choice;
• restart the device.

The changes will take effect after a reboot. The only inconvenience of the program is that you need to activate root access for it.

It is recommended that you first copy all data to a flash drive or to the cloud to avoid losing important information.

Problems and solutions

Lost archive password

If you have protected the archive with an access code, but have forgotten it, the computer program Passware ZIP Password Recovery will come to your aid, the process of using it is simple. You just need to download the archive, after which the utility will begin working using a heuristic method, as well as using “brute force” (brute force) on the vocabulary database, which includes about half a million words in English.

Analogues of the application are AZPR, FZC, FCrackZip, also available on Windows.

Unsupported format

If any photo processor rejects your request for this reason, use image conversion services - for example, convertio.co, cloudconvert.com, 123convert. You can also simply transfer the media to an archive, since these types of files work with any format.

Too much expansion

Some editors do not work with images that have a large distance in length or width, and poorly optimized applications in this case can completely slow down the entire operating system, which will require you to restart the device. In this case, you should try utilities running in browser mode, since there the processing is carried out on the server side, and you only receive the final file with the specified parameters.

Non-standard aspect ratio

This point is identical to the previous one, since the most likely “collision” with it is possible on VKontakte, which does not accept pictures where the size of one part is significantly larger than the other - for example, it will not be possible to load images 1x1000, 3x4000 and the like, which forces you to use other options .

Wrong picture title

If this error occurs, remove all special characters and the Cyrillic alphabet from the file name, or better yet, leave only the Latin alphabet. You can change the name back after optimization.

There is nothing complicated about optimizing pictures by reducing their size, and you don’t need to download any utilities either - there are web services that allow you to reduce the “weight” of a picture. The tools built into Android 4.0+ will also help, represented by cropping images, and a more universal option is to “pack” the content into an archive that can be read using special programs available on gadgets of all types.

Change resolution using Android Studio

To change the screen resolution on Android via the command line, you need Android Studio. You can install it on the website of the same name. After the download is complete, you must run the program and accept the terms of the agreement. Then you should simply click “next” until the files are unpacked, click “finish” and close the program. After this, you must follow these steps:

• connect Android to computer via USB;
• open command line;
• enter the command “adb shell dumpsys display | grep mBaseDisplayInfo";
• press Enter.

On the monitor screen you can see the characteristics of your smartphone or tablet. To the right of the word “Density” is a number with a screen extension. You need to enter the desired number, enter the command “adb shell wm density DPI && adb reboot” and press Enter. The new screen extension will appear after rebooting the device.

Although you can change the screen resolution on Android in different ways, it is impossible to change it higher.

The number of pixels cannot be increased due to the physical parameters of the display.

Reducing photo size via browser

There are many online services available on the Internet that allow you to reduce, enlarge, and rotate images. Finding them is easy: just enter the appropriate query into the search bar of your browser, for example, “Reduce photo size online.” We press the search button and see a huge number of different sites. We recommend choosing services from the first search page.

Online services for reducing photo size

Let's move on to the first service we come across. By the way, they all have similar functionality. Click on the field to upload a picture, then select the desired picture in the smartphone gallery. We wait for the image to display and change its size. The most convenient way is to use the percentage slider. For example, you need to reduce the photo by half. Then in the “Percentage” field indicate the value “50” and click “Resize”.

Resizing a photo

The procedure usually takes a few seconds. After this, you will need to click on the download button and download the formatted image.

Uploading the modified image

As you can see, in a few clicks we managed to reduce the size of the photo on Android.

Smart Video Compressor and resizer

No comments are needed here; the purpose of the application is clear by the name. Unlike the option above, this program gives the user almost no choice. She asks at what speed to squeeze, and then squeezes. The method is quite inconvenient, because it does not allow you to play with the settings. Link to the program is here.

Video Dieter 2

From now on, we will not describe in detail each stage of setting up the program and working with a video fragment, because it is similar for each program. We will only describe the main functionality of the software, the result of the work, as well as its features. Next up is an alternative to the above solutions with a rather interesting name. The software is designed for video trimming, audio extraction and compression with minimal quality loss. You can install it using the link here https://play.google.com/store/apps/details?id=com.outplaylab.VideoDiet2. The only feature worth noting is the paucity of choice of quality for the final file.

Reduce Image Size - Nothing extra

If you are looking for a program that will simply compress photos without taking up a lot of space, then Reduce Image Size is for you. At the same time, you are free not only to change the file size, but also to convert it into different formats - from standard jpeg to the not so common svg. Needless to say, Reduce Image Size is also beyond praise as an image viewer?

Photoczip - Made according to the all-in-one principle

Photoczip targets only one thing. It should compress the size of photos (and other images), and, according to the developers, it does this by losing image quality. An additional bonus will be the conversion of compressed photos into a Zip archive. In addition, you can convert photos in PNG formats to JPG, and save, delete and edit tags of the original photos. Well, if you care about the uniqueness of the photo, you can also add a watermark to the image. Additionally, the Photozip app is completely free and has no ads. And you rarely see something like this today.

Reduce photo online: instructions.

On this page you can reduce photos online for free and without registration. To resize a photo down, follow these steps:

Step 1. Load the photo you want to reduce into the application window. You can drag it or open it through the “Browse…” of your browser (you need to click anywhere in the interface).

Step 2: Resize the image using the top margins. To make a photo smaller, enter the required numbers in the width and length fields. Also, for this purpose you can use the sliders located under the fields. By default, proportional mode . This means that width and height are interrelated and change simultaneously. If you need to set the width and height separately, then turn off the proportional mode by clicking on the icon in the form of a chain link (which is located between the size fields).

Step 3: Click Create (blue button on the right). The photo will be reduced automatically and a preview window will open in which you can evaluate the result. If you are not satisfied with the size of the picture, then click on the “Back” button and return to editing.

Step 4. Download the thumbnail photo. Click on the "Download" button and download the thumbnail image to your computer.

If you want to resize another photo, click on the red cross in the upper left corner and the work area will be cleared. You will then be able to download and resize the next image.

Video Transcoder

This option is not for novice users. It features an abundance of settings, ranging from video format to codec and frame rate. The audio track was also not “offended”, because there is a separate section for it, where the bitrate and frequency are selected. In general, those who have worked in professional video editors, such as Adobe Premier Pro, will definitely love this program. And here is the link to it. Go ahead.
