β Frequently Asked Questions
Resizing itself (changing dimensions) can cause softening when enlarging. We recommend only scaling down to preserve detail. Output quality is also controlled by the quality slider for JPEG/WebP formats.
Currently only the first frame of a GIF will be resized. For animated GIFs, a specialized tool is needed.
No β all resizing happens in your browser using HTML Canvas. Your image never leaves your device.
