Xiaomi and Redmi smartphones today have powerful cameras that can capture incredible detail. But the price for high resolution is that a file can take anywhere from 5 to 15 megabytes to fill the device's internal memory. When the gallery is full, the system is slower, and the ability to take new pictures disappears at the most inopportune moment, and it's at these moments that users are faced with the question of how to quickly and efficiently make a photo smaller in size while maintaining acceptable image quality.
There are many ways to address this, from built-in MIUI shell features to third-party utilities. Image compression frees up gigabytes of space, speeds up the sending of files via instant messengers, and saves traffic when uploading to the cloud. It’s important to understand the difference between changing resolution (reducing the number of pixels) and compression (reducing the weight of a file due to encryption algorithms). In this article, we’ll look at all the available methods to help you manage your smartphone’s media library.
Before you start mass-deleting or modifying the originals, you need to back up important images. Files always carry a minimal risk of data loss, so first save the originals to an external drive or computer. This rule is especially true for those who plan to process hundreds of photos at once.
Use of built-in tools of the MIUI Gallery
The MIUI shell and its newer version of HyperOS have a fairly advanced built-in editor that allows you to perform basic operations to resize the image. You do not need to download additional applications for simple tasks. To use this method, open the standard Gallery app, select the desired photo and click on the Change button (usually an icon of a pencil or sliders).
Here you can change the physical dimensions of the image in pixels. Standard ratios such as 1:1, 4:3 or 16:9 will help quickly adapt the photo to the requirements of social networks. However, it is worth remembering that simple framing trims part of the frame, rather than compressing the entire file. To change the resolution without trimming the edges in some versions of the firmware, the function “Resize” is available in the option menu (three dots or the “More”).
⚠️ Note: The built-in Xiaomi editor can create a copy of the file while saving, leaving the original intact, or replace the source depending on the settings. Always check which file you are editing so that you do not accidentally lose the original quality.
If the built-in tools can not achieve the desired weight of the file, you should pay attention to the parameters of saving. Some versions of the gallery allow you to choose the quality of exports. Decrease in quality from "High" to "Middle" can reduce the file size by 2-3 times with virtually no visual loss of detail on the smartphone screen, this is the best option for those who do not want to overload the system with unnecessary applications.

Use the Cleanup feature in Xiaomi’s Security app – it often finds duplicates of similar photos that take up space and suggests removing them with a single click.
Third-party photo compression apps
When standard functionality is not enough, specialized applications from the Google Play store come to the rescue, offering more flexible compression settings, allowing you to accurately control the final file size. Leaders in this niche are Lit Photo, QReduce and Image Size. These programs use advanced compression algorithms that preserve visual clarity of the picture, removing redundant data that is invisible to the eye.
Consider the advantages of using specialized software:
- 📉 The ability to set an exact target file size (e.g., compress to 200 KB to download to a website).
- 🖼️ Package processing: compressing dozens and hundreds of photos at the same time.
- 📊 Visual comparison of the original and the compressed version before saving the result.
- 🎚️ Flexible setting of quality and resolution parameters.
When installing these applications, pay attention to the permissions you request. It only requires access to media files and storage. If the application requires access to contacts, microphones or geolocations without an obvious need, it is a wake-up call. Data security should come first in the digital age. Choose programs with high ratings and a lot of feedback.
One popular solution is the QReduce app, which has a minimalist interface and no intrusive advertising. Once you upload a photo, you can select Reduce Size mode and slider the desired weight in kilobytes. The app automatically selects the optimal compression level. This is especially useful when you need to prepare documents or photos to be sent through messengers that have limits on file transfer.
Changing camera settings to reduce the weight of the images
The most effective way to combat overcrowded memory is to prevent files from being too heavy. Xiaomi's camera is often set to the highest resolution and best quality by default. By changing these settings, you can save a lot of space each time you shoot. To do this, open the Camera app, click on the menu (three bars in the corner) and go to Settings.
In the photo size or resolution section, select below the maximum. For example, instead of 108 MP or 64 MP, set 12 MP or 24 MP. For viewing on a smartphone screen and even printing A4 photos, this resolution is more than enough. The difference in file weight can be tenfold: a 108 MP shot weighs about 20-30 MB, and 12 MP only 3-5 MB.
| Permission | Approximate file size | Photo count at 64 GB | Recommendation |
|---|---|---|---|
| 108 MP | 25MB | ~2 500 | For professional printing |
| 64 MP | 15MB | ~4 200 | For detailed nature pictures |
| 50 MP | 12MB | ~5 300 | Standard for flagships |
| 12 MP | 4MB | ~16 000 | For everyday photography |
Also worth paying attention to the save format. The camera settings often have a switch between JPEG and HEIF (or HEIC) formats. HEIF format provides better quality at a smaller file size compared to the classic JPEG. However, you should be aware that older devices or some computers may not open this format without installing additional codecs.

Online Services for Quick Optimization
If you need to compress a few photos and you don't want to install unnecessary apps, online services will come to the rescue, they work right in the Chrome browser or MI Browser on your phone. Popular platforms like TinyPNG, CompressJPEG or ILoveIMG use smart lossy compression algorithms that are almost invisible to the human eye.
The process of working with these services is as simple as possible. You go to the site, download the image, the server processes it and offers to download an optimized version. The main advantage is that there is no need for a powerful smartphone processor, all the computing load is placed on the server. This also means that the device's battery is less drained than when you run heavy local applications.
⚠️ Note: When using online services, your photos are uploaded to a remote server. Do not use open converters to compress confidential documents, passport photos or snapshots.
Another advantage is cross-platform, you can start processing on your phone and end up on your tablet or computer, because everything happens in the cloud, but it requires a stable Internet connection to work, and if you're in a low-reception zone, it can take a long time to download and upload files.
Using Cloud Storage and Google Photos
Google’s ecosystem offers one of the best solutions for Android owners, the Google Photos app, which not only stores your photos in the cloud, but also automatically compresses them to save space. The Save Space feature (formerly known as High Quality) allows you to store unlimited amounts of photos (with some restrictions in new tariffs) in compressed form.
To activate this feature, open the Google Photos app, click on your profile avatar and select Photo Settings → Storage Statistics → Change Size. The system will suggest replacing the originals with compressed versions. This action will free up a significant portion of your Xiaomi internal memory. Google's algorithms do a great job of balancing quality and size.
In addition, cloud storage allows you to create “smart albums” and delete already uploaded and processed photos from the device, leaving them only in the cloud. This makes your phone an easy terminal to view, and all heavy data is stored on servers. If necessary, you can always download the original back.

Comparison of methods and selection of the optimal solution
The choice of method depends on your specific tasks. If you want to quickly send a photo to WhatsApp, a built-in editor is enough. Professional applications with manual configuration are suitable for photographers preparing a portfolio. For the average user who wants to just free up space, the best choice is a combination of changing camera settings and using cloud storage.
Let’s look at the key selection factors:
- 🚀 Speed: Online services and embedded tools are the fastest.
- 🛡️ Privacy: Local apps and built-in gallery are safer than cloud services.
- 🎨 Quality: Specialized applications give better control over the outcome.
- 💾 Thousands of photos need packet handlers or a cloud.
Remember that regular gallery cleaning is the best memory loss prevention: periodically review the Screenshots and Downloads folder, delete blurred frames and duplicates. Modern Xiaomi smartphones have a Clean feature that automatically finds similar images and suggests leaving only the best.
💡
The best strategy is to shoot in reasonable resolution (12-50 MP), use the cloud for archives and compress photos only before sending or publishing in social networks.
