Redact Image
Permanently hide sensitive details with solid black rectangles.
Processed privately on your device
Upload once, then move through every photo tool without uploading again.
Helpful guidance
Upload an image, then drag across each name, number, face or other detail that must be hidden. Add as many rectangles as needed.
Use Undo to remove the most recent region or Clear to start the markings again. This tool intentionally uses solid black boxes rather than reversible visual effects.
Export flattens every box into the downloaded image pixels. Inspect the final preview carefully before sharing it.
Frequently asked questions
Can the redaction be removed from the download?
No. Solid black pixels are flattened into the exported copy, so the covered source pixels are not included there.
Can I hide multiple areas?
Yes. Drag repeatedly to add any number of rectangular regions before export.
Does Undo change my original file?
No. It only removes the latest pending box from the editor; your original file is never modified.
Is a sensitive document uploaded?
No. Drawing and permanent export happen locally in your browser.
