Protected reframe
Create aspect ratios while preserving selected regions.
Mark logos, prices or faces that must remain completely visible. Crop uses an integer translation without resizing; padding adds transparent space. Requested aspect ratios are rounded to whole pixels. A crop that cannot include every box is reported as impossible.
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
Geometrically impossible crops are reported; no generative fill or invented detail.

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.
