On Android devices, we can easily check the file size of photos and delete them if they take up too much memory. However, on iOS, we cannot check the file size of photos in the Photo Album. With a few tricks, though, we can still check the file size of photos quite easily.

Step 1: Open the photo you want to check the file size of and tap on the Share icon (1) => Save to Files (2).

Step 2: Select the path to save the photo as iCloud Drive (1) => select the folder (2) => Add (3).

3. Use the Shortcuts app to check photo file size
Step 1: Open the Shortcuts app. If your device does not have it installed, download it from the following link (Requires iOS 12 or later): https://apps.apple.com/vn/app/shortcuts/id915249334
