Preserve what matters
Encode images within explicit size and preservation constraints.
Choose exact rendered-image properties to preserve. The ordered search tries PNG, WebP and JPEG encodings, several qualities and (when permitted) sizes. Unsupported requirements: EXIF, ICC profiles, DPI, animation, PDF/vector content and exact original compressed bytes.
Static PNG, JPEG, WebP • up to 20 MiB / 20 megapixels • 90-second operation limit • 40 million selected pixels total • runs locally • exported raster files omit original metadata. Colours are the browser-rendered sRGB pixels, not a print colour proof.
How it works
- Review your inputs and the supported scope.
- Set constraints, run the operation and inspect the evidence.
- Reopen downloaded output before using it.
Example & practical use
Enter your own files or measurements; review the computed result and its stated limits.
Limits and help
PNG/JPEG/WebP raster only; unsupported metadata, animation and profile preservation is rejected.
Your files are yours.

Troubleshooting
Check the original file format and selection limit. Renaming an extension does not convert a file. For a very large image, close other heavy tabs and try a smaller copy.
