Still JPG, PNG or WebP. Up to 20 MiB and 24 megapixels each. Nothing is uploaded.
Your images
One image. Keep the originals; downloads are separate copies.
Opaque rectangles
Only solid black masks are exported. Inspect the full image for names, reflections and other visible clues. Your original stays unchanged.
PNG preserves alpha. Browser colour conversion can change appearance; the original colour profile is not copied. Files and settings are cleared when you leave.
How to use it
- 1
Choose one JPG, PNG or WebP screenshot or photo.
- 2
Drag over private details or add rectangles with the keyboard controls. Adjust each rectangle using its pixel coordinates.
- 3
Download the flattened PNG and reopen it to review everything you intend to share.
Before you export
Every exported rectangle is solid black and replaces the underlying pixels in a new PNG. There are no editable layers in that exported image. The original file remains unchanged on your device.
Cover the entire private detail, including nearby edges. Check for reflections, other names and information revealed by context. Flattened redaction does not make every image safe to share.
