how to redact an image online.
Three steps, all on this device — nothing ever uploads.
Load your image
Drag a photo or screenshot in, pick a file, paste from your clipboard, or fetch it from a URL. It stays on this device.
Draw black boxes
Toggle redact mode (B) and drag over anything private — names, account numbers, faces, license plates, addresses, API keys. Move or remove boxes until it's right.
Download the PNG
The boxes are burned into the pixels at full resolution, entirely in your browser. The export is a fresh PNG, so the original file's EXIF and GPS metadata isn't copied into it.
why solid boxes, not blur.
Solid boxes destroy pixels. Blur just hides them badly.
Blur can be reversed
Blurring and pixelation are reversible more often than people think — blurred text can be sharpened back, and pixelated characters can be brute-forced by re-rendering candidate strings until the mosaic matches.
Boxes replace pixels
A solid box has no such weakness: the pixels underneath are replaced, not obscured. The download is re-rendered from a canvas, so there's no hidden layer to peel back — the classic failure of PDF "redactions" drawn over selectable text.
What people redact
Screenshots before posting them — bank statements, support tickets, chat logs, error messages with API keys — and photos with faces, license plates, ID cards, or home addresses in them.
common questions.
Privacy, metadata, and what the tool can and can't do.
Is my image uploaded to a server?
No. Loading, redacting, and exporting all happen on a canvas in your browser. The only network traffic is an anonymous download counter — the image bytes never leave your device.
Can the black boxes be removed from the downloaded image?
No. The boxes are burned into the pixels at full resolution when the PNG is generated. There is no layer, mask, or hidden text underneath to peel back.
Does the download keep photo metadata like GPS location?
No. The download is a brand-new PNG rendered from the canvas, so EXIF data from the original file — including GPS location, device model, and timestamps — is not copied into it.
Why solid black boxes instead of blur?
Blurred or pixelated text can often be reconstructed with deblurring and brute-force techniques. Solid boxes replace the underlying pixels entirely, so there is nothing left to recover.
Is it free?
Yes — free, no account, no watermark.
Can I redact a PDF?
Not yet — the tool works on images (PNG, JPG, screenshots). To redact a PDF today, export its pages as images first. PDF support is on the roadmap.
