Limits
- Up to 20 images, 20 MiB each, 8192 pixels on an edge, and 16 million pixels. Animated GIFs are refused.
- JPEG output uses 80 percent quality. Transparency becomes white.
- Processing runs away from the page and can be cancelled. Preview addresses are released when you leave or replace the image.
- Files over 256 KiB are refused so the Base64 text is never cut off.
- Desktop limits are provisional. Physical mobile and Safari verification remains open.
