Blur a face in a photo online, free
Before you post a picture of a crowd, a classroom or a screenshot with people in it, you may need to hide faces. BolCaps Privacy Blur finds faces for you and blurs them, all inside your browser. Your photo is not uploaded to any server.
Blur faces nowHow to do it
- Open Privacy Blur.
- Add your photo (or a video).
- Faces are found automatically. It can also find phone numbers, emails, addresses, ID numbers and QR codes.
- Check each box: untick anything you want to keep, and draw a box by hand over anything it missed.
- Choose blur, pixelate or a solid cover, then download the image.
Check before you share
Automatic face detection can miss faces that are small, turned sideways, partly hidden or in poor light. Always look over the result before posting. For strong privacy, a solid cover is safer than a light blur.
Why on-device matters
The AI model downloads once to your browser and runs there, so a sensitive photo never has to leave your phone or computer.
