HOW IT WORKS
How to blur faces online
Hide identities in photos in three steps
- 01
Upload the photo
Pick or drag a photo into the editor — it opens right client-side, no account needed.
- 02
Select the faces
Circle each face with brush, rectangle or lasso. Adjustable brush size covers even dense crowds.
- 03
Pick an effect and export
Switch between gaussian, pixel, noise and solid cover, preview, then download.
Four cover effects
Gaussian looks natural, pixel is thorough, noise resists recognition, solid cover is strictest.
Never uploaded
Everything renders on the browser Canvas — originals stay on your device.
Edge margin protection
Expand a region a few pixels outward so scaling or compression never re-exposes a face.

FAQ
Frequently asked questions
Can faces still be recognized after blurring?
Strong gaussian or pixelation defeats the naked eye. For adversarial analysis use noise or solid cover.
Too slow to brush over a crowd?
Draw one rectangle over the crowd with pixelation, then touch up any exposed faces with the brush.
Are photos uploaded anywhere?
No. Selection and rendering run entirely client-side — it even works offline.
Can I undo a blur?
Yes. Multi-step undo/redo is supported, and you can always restart to get the original back.
