Blur / Pixelate Image
Blur or pixelate a region to hide faces, license plates, or private info. In your browser.
Blur or pixelate part of an image to hide a face, a license plate, a home address, or any private detail before you share it. Draw a box over the area, choose blur or pixelate, set the strength, and the rest of the photo stays sharp. It all runs in your browser, so the image is never uploaded and never leaves your device.
This is built for redaction: cover what should stay private, keep everything else clear, and download a clean copy. No signup, no watermark.
Drop an image to blur or pixelate
Drag a box over faces, plates, or private info
Drag a rectangle over the area to hide, then click Apply. Repeat for multiple areas.

About Blur / Pixelate Image
Blur or pixelate any part of an image to hide faces, license plates, addresses, or other private details before sharing. Drag a box over the area, apply, and repeat as needed. Everything runs in your browser — the photo never uploads.
How to use the Blur / Pixelate Image
- 1
Open the image
Drag in a photo or tap to select one. It loads locally in your browser, with no upload and no server-side copy of your file.
- 2
Select the area
Drag a box over the face, plate, name, or anything sensitive. Add more boxes to cover several spots in one pass.
- 3
Blur or pixelate, hard
Pick blur or pixelate and push the strength up. A strong, coarse setting destroys the underlying detail so it cannot be recovered.
- 4
Download and verify
Save the redacted copy, then zoom in on the result to confirm nothing readable peeks through before you share it.
Blur vs pixelate, and why strength matters
Blur smears neighboring pixels into a soft smudge; pixelate replaces a region with a few large solid blocks. Both hide detail, but only if you go far enough. A weak blur or a coarse-but-shallow pixelation can sometimes be partly reversed or read by eye, because traces of the original survive. The safe approach is a strong, irreversible setting: a heavy blur radius or large pixel blocks that flatten the area into mush. The goal of redaction is to permanently destroy the information, not just make it slightly harder to read.
Redact before you share, every time
- Always redact on a copy and check the saved file; the preview can look stronger than the export.
- Cover the whole sensitive element with margin, not just the center, so edges of a plate or word do not leak.
- Do not rely on placing a shape "on top" in some apps; a real blur changes the pixels themselves so nothing hides underneath.
- Once an unredacted version is posted, sent, or backed up, you cannot un-share it. Redact first, then upload.
- For faces and plates, prefer a heavy pixelate or strong blur over a light one; light effects can sometimes be undone.
Quick tips
- ✓Push the strength higher than feels necessary; a barely-blurred plate or face can still be read or partially reconstructed.
- ✓Cover sensitive areas with a little extra margin so the edges of text or a number plate are fully obscured.
- ✓Always redact a copy before sharing; once the original is sent or uploaded, you cannot pull it back.
- ✓Zoom all the way in on the downloaded file to confirm nothing readable survived, especially small text.
- ✓Use multiple boxes in one pass to hide several faces, plates, or address lines without re-loading the image.
Frequently asked questions
Blur or pixelate — which should I use?
Both hide detail. Pixelate gives the recognizable mosaic look; blur is softer. For truly sensitive info, use a strong setting so the original can't be reconstructed.
Can I blur more than one area?
Yes — draw a box, click Apply, then draw and apply again for each region. Effects bake into the image as you go.
Is the blurred image safe to share?
The effect is permanent in the exported PNG — the hidden pixels are replaced, not just covered. Use a high strength for anything truly sensitive.
Should I use blur or pixelate to hide a face or plate?
Either works if it is strong. Use a heavy blur radius or large pixel blocks so the underlying detail is flattened and cannot be read or reconstructed.
Can a blurred area be un-blurred later?
A weak blur can sometimes be partly recovered. A strong, irreversible blur or coarse pixelation permanently destroys the detail, which is why high strength matters for privacy.
Is my photo uploaded when I redact it?
No. The blur is applied in your browser on your device. The image is never sent to a server, so your private details stay with you.
