Add one image, then drag rectangles over the areas to hide.
Drag on the image to draw a rectangle.
How to use it
- Add one image and drag a rectangle over an area to hide.
- Choose solid or mosaic per rectangle; delete or adjust any of them.
- Export the flattened copy and check the result before sharing it.
Limits & formats
One image per run, up to 20 MB and 25 megapixels. Mosaic works by pixelating the covered area of the exported copy. Always open the exported file and check it yourself before sharing — heavy downscaling elsewhere can partially reveal very light mosaics, and YYSI does not claim every mosaic is mathematically irreversible. Solid fill is the safest option for sensitive content.
