Blur & pixelate faces in a photo

Hide faces, plates or screens before you post — in your browser, nothing uploaded

Drag the box over each face (or plate, or screen); add more boxes and resize from the corner. Pixelation is ideal for faces — for sensitive text, switch to solid black.

How to blur a face in a photo

  1. Add your photo. It is read locally — never sent anywhere.
  2. Drag the box over the face (add one box per face) and pick pixelate, blur or solid black.
  3. Download. The effect is flattened into the image, and the original metadata is dropped too.

Pixelate, blur or black out?

For faces, pixelation is the safest everyday choice — it destroys detail in blocks rather than smearing it. For text (names, addresses, account numbers), always use a solid black bar: research has shown blurred or pixelated text can sometimes be reconstructed. Switch the effect here, or use the dedicated redact tool.

Only need to strip the hidden GPS/EXIF data? Use the remove-metadata tool. Marking a copy with "for X only"? Use the watermark tool.

Frequently asked questions

Should I blur or pixelate a face?

Both hide identity well for a casual photo. Pixelation (mosaic) is the safer default because it discards the underlying detail in blocks; a light blur can sometimes be partially reversed, so use a strong setting — or solid black for maximum certainty.

Is blurring safe for hiding text, like names or account numbers?

No — blurred or pixelated text can sometimes be reconstructed. For text, use a solid black bar instead: switch the effect to solid black here, or use the redact tool.

Is my photo uploaded anywhere?

No. The photo is processed entirely in your browser with the Canvas API. Open DevTools and watch the Network tab — nothing is sent.

Does it also remove the photo metadata?

Yes. Re-encoding the image on export drops the original EXIF/GPS metadata. To only strip metadata without editing the image, use the remove-metadata tool.
