Frequently Asked Questions
Does cropping reduce quality?
No. Cropping copies the selected pixels at their original resolution. The only quality change comes from re-encoding, so choose PNG or a high JPEG quality if the file will be edited again later.
How do I crop to a perfect square?
Select the 1:1 ratio preset. The crop box then stays square however you drag it, which is what profile pictures and Instagram grid posts need.
What aspect ratio should I use?
1:1 for profile photos and product grids, 16:9 for video thumbnails and presentations, 4:5 for Instagram portrait posts, and 9:16 for stories and reels. The presets cover each of these.
Can I crop an image on my phone?
Yes. The crop handles are sized for touch and the image scales to your screen. The crop is applied to the full-resolution original, not the on-screen preview.
