How to change the size of the photo on the phone Xiaomi: all the ways

Xiaomi, Redmi and POCO smartphones allow high-resolution photos — from 12 MP to 200 MP in flagship models. However, such pictures take up a lot of memory, slowly load into messengers and social networks, and sometimes simply do not meet the requirements of platforms. You can change the size of the photo on the Xiaomi phone both with standard MIUI tools and with third-party applications — without loss of quality or with its optimization for specific tasks.

In this article, we will analyze all the current ways: from the built-in Gallery editor to professional tools like Lightroom or Snapseed. You will learn how to reduce the weight of photos for Vkontakte, Instagram or WhatsApp, while maintaining the readability of details, as well as how to change the physical dimensions of the image (in pixels) for printing or web design. RAW-files (.dng format) that support many Xiaomi models starting with the Mi 10 and Redmi Note 11 Pro+.

1. Standard editor in the appendix "Gallery"

The easiest way to resize a photo is to use the built-in editor in the Gallery app (or Google Photos if installed by default), which requires no additional software installation and is suitable for basic optimization of images before sending them to instant messengers.

To reduce the size of the photo:

1. Open the Gallery app and select the desired image.
2. Click on the edit icon (pencil or three dots → Edit).
3. Go to the Pruning and Turning section (the square icon with corners).
4. In the bottom panel, select Size or Change Size (depending on the MIUI version).
5. Set new parameters in pixels or percentages of the original. For example, for Instagram 1080×1080, and for VKontakte 2048×1536.
6. Save the changes by selecting Save as a copy so you don’t lose the original.

3. Professional Size Change in Lightroom Mobile

For advanced users who want to control compression quality, Adobe Lightroom is a good app, which allows you to resize your photo to take into account DPI (dots per inch), which is important for printing, and offers tools for saving parts as you shrink.

1. Install Lightroom from Google Play and import photos.
2. Click on the export icon (arrow up) → Export as.
3. In Image Size, select: Long side - specify maximum size in pixels (e.g. 1920 for Full HD). Resolution - set 300 DPI for printing or 72 DPI for web. Quality - choose 80-90% for weight-quality balance.

Ready.

Xiaomi Owners’ Tip with RAW: If you shoot in.dng format, Lightroom will allow you to export it to JPEG with the right resolution, while you can pre-adjust white balance, exposure and sharpness.

4.Fast compression via the Photo & Picture Resizer app

• 🖼️ For printing - Lightroom with 300 setting DPI.
• 🔄 For RAW-Files: Lightroom or Snapseed only.

• 📉 Too much compression: At quality below 70% in JPEG Solution: 80-85% for the web, 90-100 for printing%.
• 🖼️ Loss of loss EXIF-Data: Some applications delete the meta information about the shooting. Solution: Check your export settings or use Lightroom.
• 📱 Lack of memory: During processing RAW-files (.dng) may not have enough RAM. Solution: Close background applications or use a PC.
