FAQ
Are my images uploaded to a server?
No. Image decoding, crop selection and export all happen locally in your browser — files are never uploaded to any server, secure and fast.
How do I crop a square avatar?
Choose the 1:1 ratio so the crop box locks to a square, then drag to adjust position and size and export.
Can I crop precisely by pixel?
Yes. Besides drag selection, you can enter the X, Y coordinates and width/height in pixels in the parameter panel for precise cropping.
Will cropping a transparent PNG keep the transparent background?
Yes. Exporting as PNG or WebP keeps the alpha channel; if you export as JPG, transparent areas are filled with the chosen background color.
