Modern smartphones Android take photos with a resolution of up to 48 MP and higher, which leads to files weighing 10-20 MB - even for ordinary pictures. Such images take up space in memory, take a long time to load into instant messengers and social networks, and when sent by mail they can be blocked due to restrictions on the size of attachments. But a decrease in quality does not always mean a loss of detail: the correct settings can reduce the weight of the file by 3-5 times without visible deterioration of the picture.
In this article Let's look 7 proven ways reduce the quality of photos directly on your phone - from built-in tools Android to specialized applications and online services. You will learn how to change the resolution when shooting, compress finished images without losing data, and which formats (.jpg, .webp, .heic) are best to use for different tasks. And also - how to avoid common mistakes, due to which photographs lose clarity or color.
1. Camera settings: shooting in reduced resolution
The easiest way to avoid bulky files is initially shoot in a lower resolution. Most smartphones (including models Samsung Galaxy, Xiaomi Redmi, Google Pixel) allow you to select the resolution directly in the camera settings. For example, instead of standard 12 MP you can set 8 MP or 5 MP โthis is enough to print photos in 10x15 cm format or publish in Instagram.
To change settings:
- Open the application Camera.
- Tap on the โ๏ธ (settings) icon or swipe your finger across the screen to access additional options.
- Find section
ResolutionorAspect ratio(on some phones -Photo quality). - Select a lower value, for example,
8M (3264ร2448)instead of12M (4032ร3024).
Important: on some flagships (for example, Samsung Galaxy S23 Ultrawhen selecting a lower resolution 12 MP the video mode is turned off. Also note that 8K for video. Also note that digital zoom at a low resolution it gives more noticeable effects. artifacts.
If your camera does not have an option to change the resolution, try using third-party applications like Open Camera or ProCam X โthey support manual settings even on budget smartphones.
โ ๏ธ Attention: some manufacturers (for example, Huawei and Honor) by default save photos in.heicformat, which weighs less.jpg, but is not supported by all devices. Before shooting, check the format in the camera settings!
2. Built-in Android tools: compression without applications
If photos have already been taken, they can be compressed directly in the phone gallery. Latest versions have a built-in function Android 12+ there is a built-in function image optimization, which reduces the weight of the file without any visible loss of quality. Here's how to use it:
1. Open the application Gallery (or Google Photos).
2. Select a photo and tap on the โ๏ธ icon (Edit).
3. Find the option Compress, Optimize or Export with smaller size (the name depends on the firmware).
4. Select a compression level (for example, Medium or High) and save a copy.
On smartphones Samsung this function is called Storage optimization and is located in the photo menu (three dots โ Optimize). data-i="115">and Xiaomi And Redmi a similar option is hidden in Tools โ Compress.
What is the difference between "Compression" and "Resizing"
Compression reduces the weight of the file due to optimization algorithms (for example, reducing the bitrate in .jpg), but maintaining the original resolution Resizing physically reduces the number of pixels (for example, from 4000ร3000 to 2000ร1500), which has a greater impact on quality.
Advantages of built-in compression:
- ๐น Does not require installation of additional applications.
- ๐น Saves EXIF data (information about the date, camera model, shooting settings).
- ๐น Works offline.
Disadvantages:
- โ ๏ธ Limited settings (you cannot select the exact size or format of the output file).
- โ ๏ธ On some phones, compression is applied only to the copy, while the original remains untouched.
3. Compression applications: top 5 utilities with settings
If the built-in tools are not enough, use specialized applications. We tested 5 popular utilities and compared them according to key parameters: compression level, format support, EXIF saving and interface convenience.
| Application | Max. compression | Formats | EXIF | Advertising |
|---|---|---|---|---|
| Photo & Picture Resizer | up to 90% | .jpg, .png, .webp |
โ | โ (paid) |
| Image Compressor | up to 80% | .jpg, .png |
โ | โ (banners) |
| Lit Photo | up to 70% | .jpg, .heic |
โ | โ |
| Resize Me! | up to 85% | .jpg, .png, .webp, .gif |
โ | โ (pop-up) |
| PicsArt | up to 60% | .jpg, .png |
โ | โ (video) |
For most tasks we recommend Photo & Picture Resizer โit supports batch processing, saves EXIF and allows you to precisely set the output file size (for example, "no more than 2 MB"). you need maximum control over quality, try Lit Photo โthere is a slider for manually adjusting the compression level.
Select photos in the gallery|Tap "Open with" โ Photo & Picture Resizer|Specify the target size (in pixels or MB)|Select format (.jpg or .webp)|Save a compressed copy-->
Important: when compressed in .webp format, the weight of the file is reduced by 30-50% more than in .jpg, but some social networks (for example, VKontakte) automatically convert it back to .jpg, negating the benefit.
4. Online services: compression without installing apps.
If you donโt want to download applications, use online services. They are convenient for one-time tasks (for example, compressing a photo before sending by mail) and often offer more settings than mobile utilities. We tested 3 reliable services. data-i="169">๐น Compresses:
1. TinyPNG (https://tinypng.com)
- ๐น Squeezes
.pngand.jpgwithout visible loss of quality. - ๐น Maximum file size: 5 MB (free).
- ๐น Supports batch downloading (up to 20 images).
2. ILoveIMG (https://www.iloveimg.com/ru)
- ๐น Allows you to select the compression level (
Low,Medium,High). - ๐น There is an option to change the size (in pixels or percent).
- ๐น Maximum file size: 32 MB.
3. CompressJPEG (https://compressjpeg.com/ru)
- ๐น Specializes in format
.jpg. - ๐น Shows the preliminary result (before/after).
- ๐น Limit: 10 files at a time, up to 10 MB each.
โ ๏ธ Attention: when uploading photos to online services Do not use images with confidential information (scans of documents, photos of passports, bank cards). Even if the service promises to delete files after processing, the risk of data leakage remains.
Online services are suitable for one-time compression, but are inconvenient for regular use - each time you need to upload the photo manually. For continuous work, it is better to install a mobile application.
5. Converting formats: .heic, .webp and others
Sometimes you can reduce the weight of a photo not by compression, but by converting to a more efficient format. For example:
- ๐ฑ
.heic(used in iPhone and some Android) weighs in 2 times less.jpgwith the same quality. - ๐
.webp(from Google) supports transparency (like.png) and lossless compression. - ๐ธ
.avifis a new format with better compression, but is still poorly supported by social networks.
To convert photos to Android:
- Install the application HEIC to JPG Converter (for
.heic) or WebP Converter. - Select files in the gallery and export them to the desired format.
- For batch conversion, use File Converter (supports
.heic,.webp,.avif).
Format comparison (source: .jpg, 5 MB, 4000ร3000):
| Format | File size | Quality loss | Support by social networks |
|---|---|---|---|
.jpg (90% quality) |
3.2 MB | Minimum | โ All |
.webp (lossless compression) |
2.1 MB | No | โ Except VKontakte |
.heic |
1.8 MB | No | โ Only Apple ecosystem |
.avif |
1.5 MB | No | โ Limited |
If you often send photos to WhatsApp or Telegram, convert them to .webp โthese messengers automatically compress .jpgbut leave .webp without changes.
6. Automatic compression: setting up synchronization
Many cloud services (Google Photos, Yandex.Disk, Dropboxoffer Automatic compression of photos when uploadingThis is convenient if you regularly backup pictures. For example, Google Photos there are two modes. storage: Google Photos cloud).
- ๐น
Original qualityโ files are downloaded without changes (takes up space in the cloud). - ๐น
High quality- photos are compressed to 16 MP (even if the original is 48 MP), and video - to 1080pAt the same time unlimited storage is free.
To enable compression in Google Photos:
- Open the application and tap on the profile avatar.
- Select
Photo settingsโBackup and synchronization. - In the section
Upload qualitysetHigh quality.
โ ๏ธ Attention: when choosingHigh qualityin Google Photos original photos not saved โonly compressed versions are loaded. If it is important for you to store the sources, useOriginal qualityand manually compress copies.
Similar settings are available in Yandex.Disk (Autoload โ Photo quality) and Dropbox (Camera settings โ Size of uploaded photos). The main advantage of this approach is compression occurs automatically, without your participation.
7. Manual resizing: for advanced users
If you need accurately control the final size of the photo (for example, for print or website), use manual resizing. This can be done:
- ๐ฑ In mobile applications (Photo & Picture Resizer, Resize Image).
- ๐ป On a PC using Photoshop, GIMP or Paint.NET.
- ๐ Through online services (ResizeImage.net, BIRME).
Example: you need to prepare a photo for an avatar in VKontakte (recommended size - 200ร200 pixels). Instead of uploading the original in 4000x3000, you can:
- Open photo in Photo & Picture Resizer.
- Set size 200ร200 px (preserving proportions).
- Export to
.jpgs quality 90%.
The final file will weigh 5-10 KB instead of the original 5-10 MB!
Recommended sizes for popular tasks:
- ๐ Avatar in social networks:
200ร200 px(up to 50 KB). - ๐ผ๏ธ Post in Instagram:
1080ร1080 px(up to 1 MB). - ๐ง Attachment to letter:
1600ร1200 px(up to 2 MB). - ๐จ๏ธ Print 10ร15 cm:
1200ร1800 px(up to 3 MB).
When resizing manually, pay attention to the aspect ratio If the source has 4:3 proportions, and you forcibly stretch it to 1:1, the object in the photo will be distorted.
FAQ: Frequently asked questions about reducing photo quality
Is it possible to return the original quality after compression?
No compression (especially with losses, like in .jpg) deletes some of the data permanently. Always save the original photos if they are important. Some applications (for example, Google Photos) allow you to store compressed copies separately from the originals.
Which format is better for storing photos: .jpg, .png or .webp?
Depends on the task:
.jpgโa universal format for photographs (compresses well, but does not support transparency)..pngโfor screenshots and images with text (lossless, but heavy weight)..webpโoptimal for the web (lighter.jpgby 25-35%, supports transparency).
For archival storage it is better to use .jpg with quality 90-95% or .webp lossless.
Why after compression photos become blurry?
This happens due to:
- Too much compression (for example, quality
.jpgbelow 70%). - Reducing the resolution to values below 1000 px on the long side.
- Use of aggressive algorithms (for example, in online services with the "Maximum compression" option).
To avoid blurriness, compress photos with quality not lower than 80% and keep the resolution at least 1920ร1080 px.
How to compress a photo directly when sending in messengers?
Most messengers automatically compress photos:
- WhatsApp: up to 16 MP and weight ~300 KB.
- Telegram: no compression when sending as
File, but compresses to 1-2 MB when sending asPhoto. - Viber: up to 12 MP and ~500 KB.
To send a photo in original quality, use the option Send as file (in Telegram) or archive it in .zip.
Is there a difference between compression on Android and iPhone?
Yes, there are nuances:
- On iPhone photos are saved in by default
.heic, which weighs less.jpg, but not all Androiddevices support it. - In Google Photos on iOS there is no option
High qualitywith unlimited storage - onlyOriginal quality(paid). - Compression applications Android often offer more settings (for example, choosing DPI, bitrate).
However, the basic principles (changing resolution, converting formats) work the same on both platforms.
