Can I undo a crop after saving?
Yes! Both iOS Photos and Google Photos preserve the original image. On iOS, tap Edit → Revert. On Android, the original remains in your library if you selected "Save copy."
Does cropping reduce image quality?
Cropping itself doesn't reduce quality - you're just removing pixels from the edges. However, if you crop to a small size and then try to enlarge it later, quality will suffer. Always keep the original!
Can I crop multiple photos at once on mobile?
Native apps don't support batch cropping, but you can use CropMaster in your mobile browser to crop up to 50 images at once. It works offline and processes everything on your device.
What's the best aspect ratio for Instagram on mobile?
For Instagram feed posts, use 4:5 (portrait) or 1:1 (square). For stories and reels, use 9:16 (vertical). Most mobile photo apps have these presets built-in.
Do third-party crop apps upload my photos?
It depends on the app. Always check the privacy policy. CropMaster processes everything locally in your browser - your photos never leave your device.
