Frequently asked questions
Crop or add margins?
Cropping loses the edges but fills the frame; margins keep the whole image adding bands of your chosen color.
Where does it crop?
Crops are centered: both sides lose equally.
Which formats are accepted?
JPG, PNG, WEBP, AVIF, BMP and GIF (first frame). The output keeps the original format when possible.
Is my image uploaded to a server?
No. All processing happens on your device using the browser itself; the image never leaves it.
