Frequently Asked Questions

Can I crop to a perfect square for a profile picture?

Yes — select the 1:1 aspect ratio preset and position the crop box over your subject. The result will be a perfect square, ideal for profile photos on most platforms.

Does cropping reduce file size?

Cropping removes pixels, so the output file is usually smaller than the original. The exact reduction depends on how much of the image you keep.

Will cropping a PNG keep the transparent background?

Yes. If your PNG has transparency, the cropped output will preserve that transparency in the areas that remain.

Can I undo a crop and try again?

Simply re-upload your original image and draw a new crop selection. Because the original is untouched on your device, you can always start fresh.

What is the largest image I can crop?

Images up to around 20 MB are supported. For very high-resolution files, the tool still works but may take a moment longer to process.
