Are images uploaded for processing?

Image processing runs locally in your browser. Public pages can also load advertising and optional Analytics, as described in the privacy information.

Can I use large or animated images?

Still images are limited to 20 MiB and 8 million pixels. Animated images are rejected here; use the APNG or GIF tools.

Does export preserve the original file exactly?

Pixel operations use decoded 8-bit RGBA and encode a new PNG. Higher bit depth, metadata and color-profile details may change. Compare the preview and retain your original.
