Frequently asked questions
- Why crop to a square rather than let the platform do it?
- Because the platform picks the crop for you, and it usually takes the exact centre. Cropping first means you decide what stays in frame — which matters whenever the subject is not dead centre.
- What size square will I get?
- As large as the selection you drag, taken at the original resolution. On a 4000 x 3000 photo the biggest possible square is 3000 x 3000. To land on an exact size like 1080 x 1080, crop here and then use the image resizer.
- Does cropping lose quality?
- No. The square is copied out of the original at native resolution, so those pixels are unchanged. Only enlarging afterwards would soften it.
- Can I use this without a mouse?
- Yes. Tab to the selection, then arrow keys move it, Shift with arrows moves faster, and Alt with arrows resizes. It works on touchscreens too.
- Is my image uploaded to a server?
- No. Cropping happens entirely in your own browser using the Canvas API. The file never leaves your device, and nothing is stored.
