Auto redaction tool

Auto-redact image online

Stop hand-drawing rectangles over every email and phone number. Redacted finds personal information in screenshots and photos for you, then masks it with one click. Everything happens in your browser — the image never leaves your device.

What gets detected automatically

How auto-redaction works

  1. Open the editor and drop, paste, or select your image.
  2. Click Detect text.
  3. Redacted runs OCR on the image, scans the recognised text for sensitive data, and adds a mask over each match.
  4. Review the results, add or remove masks, and adjust mask styles if needed.
  5. Download the redacted image.

Manual review still recommended

Auto-detection covers the common cases, but no detector is perfect. Always do a quick visual pass before sharing — especially for handwritten text, low-resolution photos, and unusual identifiers like internal employee IDs or licence plates.

Private by design

The OCR model and the PII detector both run locally inside the browser. There is no upload step, no server-side processing, and no account. The exported image strips metadata as well.

FAQ

Does it work on photos as well as screenshots?

Yes, but accuracy depends on text quality. Screenshots and document scans work best. Photographs with small, angled, or blurry text may need manual touch-ups.

Can I still draw masks manually?

Yes. Auto-detection adds masks for you; you can add, move, resize, or delete any of them, and you can also draw new ones from scratch.

Is anything sent to a server?

No. The OCR model and the personal-information detector run in your browser. The image stays on your device.
