Blur Image
Draw boxes over faces, plates or anything private to blur it out. Runs in your browser — nothing is uploaded.
About Blur Image
Blur Image obscures any region of a photo you select — a face, a licence plate, a document on a desk, a name badge. The blur is applied to the actual pixels and exported into the file, so the original detail is not recoverable from the image you download. It runs entirely in your browser.
Photographs pick up more than you intend. A team photo posted publicly includes people who never agreed to appear online. A picture of your new car shows the registration. A screenshot for a support ticket has a customer's email in the corner. A holiday photo has other people's children in the background. Publishing any of these unedited is a small privacy problem that occasionally becomes a large one.
In several contexts it is a legal expectation rather than a courtesy. Under GDPR, an identifiable face is personal data, and publishing bystanders without a basis for doing so is a genuine compliance issue for businesses. Journalists blur faces to protect sources, estate agents blur neighbouring house numbers, and support teams blur customer details before attaching screenshots to a ticket. Because the blur happens in your browser, the unedited original never travels anywhere.
How to Blur Image
- Select the photo you want to edit.
- Draw a box or brush over each area you want obscured.
- Increase the blur strength until the detail is genuinely unreadable, not just softened.
- Check the whole image for anything you missed — reflections and background details are easy to overlook.
- Download the blurred image.
Tips & common problems
Weak blur can be reversed
A lightly blurred licence plate or short number can sometimes be reconstructed computationally. Use a strong blur so the region is genuinely featureless rather than merely fuzzy.
Check reflections and backgrounds
Faces reflected in windows, documents visible on a desk and name badges in the background are the things people forget. Scan the whole frame before exporting.
Pixelation is the alternative
Pixelate Image produces a mosaic instead of a smear. It reads more clearly as deliberate censorship, which is sometimes what you want editorially.
Blur before sharing, not after
Once an unedited photo has been posted or sent, it can already have been saved by someone else. Edit first, then share.
Frequently asked questions
How do I blur a face in a photo for free?
Select the image, draw over the face and download the result. No signup, no watermark and nothing uploaded.
Is my photo uploaded?
No. Blurring happens in your browser, which matters here — the whole point is that the unedited version stays on your device.
Can the blur be undone?
Not from the file you download. The pixels are genuinely altered and exported, so the original detail is not present in the new image. Use a strong blur, as very light blurring can sometimes be partially reversed.
Can I blur more than one area?
Yes. Blur as many separate regions as you need — several faces in a group photo, a plate and a house number in the same shot.
Should I blur or pixelate?
Both hide detail. Blur looks softer and more natural; pixelation reads more obviously as intentional censorship. For documentary or journalistic work, pixelation signals the edit more clearly.
Do I legally need to blur faces?
It depends on where you are and the context. Under GDPR an identifiable face is personal data, so businesses publishing photos of people generally need a lawful basis. Blurring is the simplest way to avoid the question entirely.
