How are the faces detected?

With MediaPipe’s BlazeFace model, which runs in your browser. The photo is scanned at several scales so that small faces in the background of group shots are found too.

What if a face is not detected?

Drag over the photo to draw an area by hand; it gets the same effect as the detected faces. You can also use this for licence plates, house numbers or documents.

Can I leave some faces visible?

Yes. Every area has a box: tap it to turn it off and that face stays as it is. The counter shows how many areas are hidden.

Is the blur reversible?

No. Blur and pixelation are applied to the pixels of the downloaded image, and the solid cover replaces them completely. For maximum safety on sensitive photos, use the solid cover.

Does the downloaded image keep its quality?

Yes. It keeps the original resolution; only the hidden areas change. PNG files stay PNG and the rest are saved as JPG.

Are my files uploaded to a server?

No. Everything is processed inside your browser and your files never leave your device. There is no upload, no queue and no temporary storage, so the tool keeps working even if you go offline after the page has loaded.

Yes. There is no sign-up, no watermark and no daily limit. The site is funded by a few unobtrusive ads around the tools, never inside your files.

Blur faces in photos

Upload a photo and every face is detected and hidden automatically. Choose blur, pixelate or a solid cover, tap a box to keep a face visible, and download the anonymized image. Detection runs on your device.

When to blur faces

Before posting photos of events, schools or streets, it is good practice (and often a legal requirement) to hide the faces of people who have not given consent. The same applies to screenshots of video calls or photos sent as evidence. Since the detection runs on your device, the original photo is never shared with anyone.

Blur, pixelate or cover

Blur looks the most natural in social posts. Pixelate makes it obvious that something was hidden on purpose. Cover replaces the area with a solid shape and is the safest option for sensitive images. To remove a person completely instead of hiding them, try Remove objects from photos.
