About the Blur & Pixelate
Blur or pixelate parts of an image to hide faces, addresses, card numbers and other private details — draw over what to redact, all in your browser.
How to use the Blur & Pixelate
- 1Drop in an image, paste one, or click to browse — JPG, PNG, WebP and iPhone HEIC all work, and nothing is uploaded.
- 2Drag across anything you want to cover. Each area is listed so you can remove one without starting again.
- 3Black out is the default and is the only option that truly destroys what was underneath — use it for card numbers, addresses and names.
- 4Click Download to save the redacted image, with the original photo's metadata stripped out along the way.
Frequently asked questions
Is this redaction tool free?
Yes — completely free with no sign-up, no watermark and no limit on how many images you redact.
Are my images uploaded to a server?
No. Everything happens in your browser — your image never leaves your device, which matters when the whole point is hiding something private.
Is pixelating or blurring enough to hide text?
No, and this is worth taking seriously. Pixelation is a reversible transform: because the same input always produces the same blocks, someone can render candidate text in the same font, pixelate it identically and match it against your image. For a known set of characters — a card number, a phone number, a house number — that recovers the original with little effort. Blur is harder to undo but still leaks structure. Use Black out for anything that matters; it paints over the pixels, so there is nothing left to recover.
When is blur or pixelate the right choice?
When you want to signal that something was there without an ugly bar — obscuring a face in a crowd shot, softening a background, or tidying a screenshot where the hidden content isn't sensitive. Treat them as cosmetic, not as security.
What's the difference between the block size and blur radius?
Block size is the width of each pixelated square, and blur radius is how far each pixel is smeared — both shown in pixels of your original image, so the number means the same thing whatever size your photo is. Larger values hide more, but neither becomes secure at any setting.
Does it remove the photo's hidden metadata too?
Yes, as a side effect. The redacted image is redrawn from scratch, so camera details, date and GPS location don't carry over. If you only want to strip metadata and change nothing else, use the EXIF Remover, which does it without re-compressing the picture.
Can I undo a mistake?
Yes. Every covered area appears in a list with its own remove button, and there's an Undo for the last one and a Clear for all of them. Nothing is applied to the original file until you download.
