Blur Face — FAQ
Add a JPG, PNG or WebP photo and the on-device AI scans it for faces, then covers each detected face with blur or pixelation. Download the protected image and share it knowing the people in it are no longer recognizable.
The tool accepts JPG, PNG and WebP images, from phone photos and screenshots to scanned pictures. It works on single portraits and group photos alike, detecting the faces it finds and letting you download the blurred result in moments.
Yes. Blurring faces here is completely free, with no signup, no watermarks on your image and no daily limits. You can protect as many photos as you need before posting them online, sending them to clients or sharing them publicly.
Both effects hide identity well, so the choice is mostly visual: blur gives a smooth, soft cover, while pixelation gives a classic blocky mosaic look. Either way, the covered face cannot be read from the downloaded image, so pick the style you prefer.
No. Face detection and blurring run entirely on your device with on-device AI, so your photos are never uploaded to a server or seen by anyone else. That makes the tool safe for family photos, workplace pictures and sensitive images.
You can process photos up to 100 MB per file in JPG, PNG or WebP format, with no daily usage limits. Extremely large or unusual images may take a little longer on older devices, because all the detection work happens locally.
A manual blur tool makes you paint over every face yourself, which is slow on group photos and easy to miss someone. Automatic face detection finds the faces for you, so a crowd shot gets the same careful privacy treatment in seconds.
Yes. The detector looks for every face it can find in the image, not just the largest one, so group photos, event pictures and street scenes get covered together. Check the preview before downloading, especially when faces are very small or partly hidden.
If no face is detected, the image is returned unchanged, so you can download it exactly as it was. Faces that are turned far sideways, heavily covered or extremely small in the frame can be harder for any detector to spot.
No. Once you download the blurred or pixelated image, the hidden facial details are permanently covered in that file and cannot be restored from it. Keep your original photo stored privately if you still need an untouched copy for yourself.
