Face Blur
To blur faces in a photo so they stay hidden, each face has to be found and then covered with a blur that cannot be sharpened back. Here every face is shrunk to a few colour cells before it is smoothed, so the detail is gone from the saved file.
How to blur faces in a photo
Add your photos
Drop one or more JPG, PNG, WebP, or HEIC photos, click to browse, or paste from your clipboard. Faces are found and blurred straight away.
Check every face
Pick a photo from the strip to see it full size. Click a face to uncover it, or drag over anything that was missed to cover it.
Choose a style
Blur is the default. Switch to solid black or large pixel blocks, and the change applies to every photo in the batch.
Download
Save one photo, or every photo in one ZIP. Each file keeps its name with -blurred added, and HEIC photos come back as JPG.
Why use this tool
Faces found automatically
Every photo is checked for faces the moment it is added. Each face is covered with an oval a little larger than the face, so hairline, ears, and chin are inside it.
A blur that cannot be undone
Each face is reduced to a handful of colour cells before it is smoothed, so the features are gone from the file. A light blur can be partly sharpened back; this one cannot.
Whole batches at once
Drop a folder of photos and they are checked one after another. A strip of thumbnails shows each result with its face count, and one button saves them all as a ZIP.
Fix what it missed
Click a face to uncover it if it should stay visible. Drag over a missed face, a name badge, or a number plate to cover that too.
Blur, black, or pixelate
Three cover styles, applied to the whole batch with one click. The preview is drawn the same way as the download, so what you see is what you save.
Nothing leaves your browser
Photos are read and blurred on your device. Saved copies carry no location, camera, or date details from the original file.
About this tool
Posting a photo of a school trip, a protest, a street scene, or a team offsite often means covering the faces of people who did not agree to be in it. Doing that one face at a time in a photo editor is slow, and an editor blur is often light enough to be partly reversed. This tool finds every face it can in each photo, covers each one with a heavy blur in an oval sized to include the hair and chin, and lets you correct the result before you save it.
Detection is good but not perfect. Faces turned fully sideways, faces shaded by a hat brim, people far away in a crowd, and faces partly hidden behind someone else can be missed, and now and then a hand or a pattern is covered by mistake. Look over every photo before sharing it: click a wrong box to uncover it, and drag over anything that was missed. For crowds, the "Look harder for small faces" option checks each photo again at a higher resolution, which takes longer and finds more distant faces.
Saved photos keep their format (HEIC becomes JPG) and carry none of the original metadata, such as GPS location or camera model. To blur a whole picture rather than just the faces, use the image blur tool or pixelate an image. To check other files for hidden location data before you share them, use the metadata stripper.
Frequently asked questions
- How does it find faces?
- Each photo is scanned in overlapping tiles at more than one size, so both large faces and small ones in the background can be found. Every face found becomes an oval that covers the face plus a margin for the hairline, ears, and chin.
- Are my photos uploaded anywhere?
- No. Photos are read, checked, and blurred in your browser and never sent to a server. The face finder itself, about 15 MB, downloads the first time you use the tool and stays saved in your browser after that.
- Will it find every face?
- Not always, so check every photo before you share it. Faces turned sideways, shaded by hats, partly hidden, or very small in a crowd can be missed. Drag over any face it missed to cover it, and turn on "Look harder for small faces" for crowd shots.
- Can the blur be reversed?
- No. Each face is shrunk to a few colour cells before the blur is applied, so the detail is thrown away rather than smudged. The solid black style removes everything, and the pixelate style uses blocks too large to rebuild a face from.
- Which files can I use?
- JPG, PNG, WebP, and HEIC photos, as many as you like in one go. Files keep their format when saved, except HEIC, which is saved as JPG because browsers cannot write HEIC. Other file types are skipped with a message.
- Are there any limits?
- Photos larger than about 24 megapixels are scaled down to fit browser limits, and the tool says when that happens. Files over 100 MB are not opened. Very large batches are processed one photo at a time, so they take a while on a slower device.
