Many Xiaomi smartphone users are faced with a situation where the screenshot taken looks blurry or takes up too much space in the device’s memory. Standard system settings often compress images to save space, which leads to loss of detail when viewing on large screens or when printing. Understanding how the MIUI or HyperOS graphics subsystem works allows you to significantly improve the result.
In this article, we will take a look at all the ways you can manage screenshot quality, learn about the hidden possibilities of RAW, the effect of display resolution on the final file, and the right compression codec, and help you keep your images as clear as possible for work or personal archives without losing important details.
It's worth noting that the concept of quality in the context of screenshots is multifaceted, and it depends not only on the settings of the camera or application, but also on the system parameters of the interface rendering. The graphics engine of the smartphone processes the image before saving, and this process can be optimized, and the correct setting of parameters will avoid compression artifacts.
Selecting a save format: PNG vs JPG
The first and most important step to improving quality is choosing the right file format. MIUI often by default, compression characteristic of the format can be activated JPG, which_lossy_ (This means that every time you save some of the information about color and detail is irretrievably simplified by the compression algorithm.
For maximum quality, the format should be used. PNG. This format uses a lossless compression algorithm (_lossless_), This is a way of ensuring that the pixels on the screenshot match the pixels on the screenshot to the ones on the display. JPG, PNG does not create characteristic “squares” or blur around text and sharp interface lines.
⚠️ Attention: Files in format PNG It takes up a lot more space in the memory of the device. If you take hundreds of screenshots every day for quick correspondence, you can switch to the computer. PNG It can be used up more quickly in free space.
You can change the format of the save through the built-in Screenshots app. After you create the picture, click on the thumbnail, then select the settings menu (three dots) and find the quality option. It is also important to consider that some older device models may not support high-quality preservation due to the limitations of the processor.
- 📸 PNG — Perfect choice for saving text, graphs and interfaces with clear lines.
- 🗑️ JPG — It is suitable only for fast transfer of screenshots through messengers, where the quality is not critical.
- 💾 WebP is a modern format that is sometimes used by the system, balancing between quality and size, but is less compatible with older PCs.
When choosing a format, you should keep in mind the purpose of using the image: If you plan to send screenshots to messengers like Telegram or WhatsApp, they will still be compressed by the server, in which case using PNG during the creation phase will not give a visible advantage, but will increase processing time.
Screen resolution and DPI settings
The quality of the screenshot depends on how many pixels the original image contains. If your Xiaomi smartphone has a high-resolution display, such as Full HD+ or 2K, but the system settings have a reduced resolution to save battery, the screenshots will be created in low quality. The system renders the interface in lower resolution, and the screenshot captures this picture.
To check and change these settings, go to Settings → About Phone → All Options → MIUI version (click many times to enter Developer Mode). Then, in the Additional → For Developers section, find Minimum Width (DPI), which changes the value affect pixel density and element scaling.
However, a more direct path to resolution control is often hidden in the display section. Some models with Snapdragon processors have the option to change the screen resolution manually. Setting the maximum value ensures that the frame buffer is complete and the screenshot inherits the native clarity of the matrix.
Settings → Screen → Screen resolution → High (recommended)Increasing DPI (dots per inch) makes interface elements smaller, but allows more information to fit on a single screen.A screenshot taken at a high DPI will contain more detail, but text can become too shallow to read without zooming.The balance between readability and detail is a key point here.
| Parameter | Impact on screenshot | Recommendation |
|---|---|---|
| Permission (Resolution) | Determines the total number of pixels | Establishing the native (maximum) |
| PPI (Denseness) | Affects the size of interface elements | Leave default or 400+ dpi |
| Frequency of update | It affects smoothness, but not statics. | It does not affect the quality of the photo |
💡
If you change the DPI in the developer settings, don't put values below 360 or above 600 unnecessarily. Extreme values can make the interface unreadable or cause some applications to crash.
Using the RAW format for screenshots
Few people know, but in a shell. MIUI HyperOS is able to save screenshots in format RAW (DNG). This is a digital negative that contains raw data from a matrix or a graphic buffer. JPG or PNG, RAW-screenshots do not pass through the system post-processing pipeline, maintaining maximum dynamic range and color coverage.
This feature is especially useful for designers and developers who need to analyze the exact colors of pixels or retouch the interface. RAW file takes up significantly more space and requires special software to view, such as Adobe Lightroom or a standard gallery with support for RAW.
To activate this feature, you usually need to include additional flags in the developer menu or use a third-party utility if the regular gallery does not provide such an option explicitly.
⚠️ Attention: Files RAW They are not intended for direct publication on social networks. JPG or PNG before sending, otherwise the recipient will not be able to open the image.
The use of RAW is only justified for professional purposes. For common tasks, such as saving correspondence or a movie ticket, this format is redundant. It takes longer for the processor to process the image at the time of creation, which can lead to a slight delay between the pressing of the buttons and the beep.
- 🎨 It saves 12-bit or 14-bit color depth against 8-bit color depth. JPG.
- 🛠️ Allows flexibility to adjust exposure and white balance after creation.
- 💾 Demands in 3-5 More free space on the internal storage.

Compression problems in MIUI and HyperOS
MIUI and HyperOS are known for aggressive memory optimization, not only for the backend applications, but also for media processing, and algorithms can automatically reduce screenshot quality if disk space runs out or data saving is enabled.
Often users notice that screenshots taken in games or while watching videos have artifacts, because the video stream or graphic buffer of a game may have a different color space than the interface, and the system tries to convert colors on the fly, which sometimes leads to distortions known as banding.
To minimize the impact of system compression, it is recommended to turn off energy saving modes while working with graphics, it is also worth checking the settings of the specific application from which you take a screenshot. Some applications (for example, banking or streaming services) may programmatically prohibit the creation of screenshots or reduce their quality in order to protect content (DRM).
It is important to distinguish between software compression and physical limitations of the screen. If there is already noise or low brightness on the screen, the screenshot will inherit these defects. HDR-contents in the display SDR-The screen (or vice versa) may also look faded on the screenshot due to improper tone mapping.
💡
Aggressive compression in MIUI is often caused not by camera settings, but by system-based resource-saving algorithms, and turning off the power-saving mode is the first step to solving the problem.
Third-party screenshot applications
If Xiaomi’s standard tools don’t meet your quality requirements, third-party solutions from the Google Play Store come to the rescue. These apps often have more flexible codec settings and allow you to save images in the original resolution without the intervention of system optimizers.
One popular solution is the Screen Master or Long Screenshot app, which allows you to not only take long screenshots, but also customize the quality of the save, watermarks and formats, and use such programs gives you more control over the final result.
When choosing a third-party app, pay attention to the permissions you request. To create high-quality screenshots, the app needs access to the display over other windows and access to the file system. Be careful of little-known programs that can collect data about your screen.
- 📱 Screen Master – a powerful tool with editor and quality setting.
- 📐 Long Screenshot – specializes in page scrolling, but retains good quality.
- 🎨 Stitch & Share – allows you to glue multiple screenshots without loss of source quality.
Using third-party software may require special permissions through ADB (Android Debug Bridge) if standard access rights are not enough, which is true for Android 13 and more recently, where Google has tightened controls over screenshots for security reasons.

Optimizing File Transfers Without Losing Quality
Even if you create a screenshot of perfect quality, a file transfer can make all the effort go wrong. Messengers and social networks aggressively compress images. WhatsApp, for example, can reduce the size of a picture by 10 times, turning a clear PNG into a blurred JPG.
To transfer high-quality screenshots, use the Document features in messengers or cloud storage. Sending a file as a document saves its original bitrate and format. It is also convenient to use Mi Share for transfer between Xiaomi devices, since this protocol does not compress data.
When uploading to social networks (Instagram, VK, Telegram), use the computer version of the site or special settings in the application if they allow you to upload photos in original quality. Telegram, for example, allows you to send photos as a file or compress them - always choose the option "File" to save details.
⚠️ Note: When sent via email, some email services can also compress attachments unless you select Original mode. Always check the settings before sending.
Storing screenshot archives also requires attention. The file system can become fragmented over time, but this rarely affects file integrity. However, cleaning the gallery cache regularly helps the system index new high-resolution images faster.
