About the Photo Redaction Tool

The Photo Redaction Tool permanently removes sensitive details from an image — faces, names, account numbers, addresses — by covering them with blur, pixelation, or a solid box. The effect is baked into the exported pixels rather than laid over the top as a removable layer, so the original detail is genuinely gone. Everything happens in your browser: the image is never uploaded, and exporting also strips the file's original EXIF metadata.

How to use the Photo Redaction Tool

  1. 1Upload the image you want to redact.
  2. 2Choose a mode: Blur, Pixelate, Black Box, or White Box.
  3. 3Drag across an area to cover it — each drag creates one rectangle. Use the sliders to adjust the size and the strength of the effect.
  4. 4Use Undo and Redo to fix mistakes, and Preview to check the result.
  5. 5Download the redacted image.

  • Removing API keys and tokens from a screenshot before posting it publicly
  • Stripping GPS and camera metadata from an image by re-exporting it

Frequently asked questions

Is the redaction permanent, or can it be reversed?

It's permanent in the exported file. The effect is applied to the actual pixels when the image is redrawn for export, so there's no hidden layer to lift off — unlike drawing a box over text in a PDF or a slide, where the original is very often still underneath.

Which mode is safest for genuinely sensitive information?

Black Box or White Box. Blur and pixelation are strong visual obfuscation, but they are transformations of the original pixels rather than a complete replacement of them. For account numbers, government IDs, or faces you must protect, use a solid box.

Does it work on a phone or tablet?

Not currently — drawing needs a mouse, so redaction works on a desktop or laptop but not on a touchscreen.

Is the image uploaded anywhere?

No. Everything is done in your browser with canvas and the file never leaves your device — which is rather the point for a tool that handles sensitive images.

Does it remove the photo's metadata?

Yes, as a side effect of how it exports. The image is rewritten from a canvas, so EXIF data such as GPS coordinates, camera model, and timestamps is not carried across to the downloaded file.
