Frequently asked questions
Can I move the crop toward an off-center subject?
There is no focal-point control here. The crop is centered; prepare a deliberate crop in Image Cropper first if necessary.
Will the output keep my JPEG format?
No. This tool exports PNG at the selected pixel dimensions, even when the input is JPEG or WebP.
