Blur or pixelate faces in a photo
Automatically detect and blur or pixelate faces in a photo.
To blur faces in photo files, upload the image, choose pixelate or blur, set the strength from 4 to 30 and download the result. The tool detects faces automatically and covers each one. It looks for front-facing faces only, so side views, tilted heads, masks, very small faces and poor lighting can be missed. Treat the output as a privacy aid and check every face yourself before you share it.
How to blur faces
Upload a JPG, PNG, WEBP, GIF or BMP up to 20 MiB. Choose Pixelate or Blur and move the strength slider, which defaults to 12. Submit the form and download the image, saved in the same format with the style added to the name. If no face is found, you get a message instead of an unchanged file.
Pixelate or blur
Pixelate replaces each face with large blocks. A higher strength means bigger blocks and less detail. Blur applies a Gaussian blur whose size grows with the strength and the face size. Pixelation is easier to see at a glance in a review; a light blur can look natural but may leave a face recognisable if the strength is low.
What the detector can miss
Detection uses a classic frontal-face detector and only considers faces at least 40 by 40 pixels. Profiles, heads turned or tilted, partly covered faces, faces in shadow and small faces in the background are often not found. It can also box something that is not a face. There are no manual boxes, so you cannot add or remove regions.
Not a guarantee of anonymity
Hiding a face does not hide a person. Clothing, tattoos, location, name tags, license plates and surrounding text can all identify someone. Use a high strength, open the result at full size and check every face. To remove camera and location data from the file, use the Strip Image Metadata tool as well.
Frequently asked questions
Does it blur every face automatically?
It blurs the faces it detects, which are mostly front-facing ones at least 40 pixels wide. Side profiles, small, covered or badly lit faces can be missed, so always review the result before sharing.
Is pixelating a face safe for privacy?
It reduces recognisability but is not a guarantee. A low strength can leave a face identifiable, and other details may still identify the person. Use a high strength and check the image at full size.
What if no faces are detected?
The tool tells you that no faces were detected and returns no image. Try a sharper, better-lit or higher-resolution photo, or hide the faces with an image editor that lets you draw the area by hand.
Should I choose blur or pixelate?
Pixelate is the clearer choice for hiding identity, because larger blocks remove more detail. Blur looks smoother, but at a low strength a face may remain recognisable. Both are controlled by the strength slider from 4 to 30.
Can I choose which faces to hide?
No. Every detected face is treated the same and there is no manual selection. If you need only some faces covered, crop the photo first or edit the result in an image editor.
