Face Mosaic: Auto Photo Blur

Before you share, blur the faces.
Photos posted to social media, messaging apps, or buy-and-sell apps often include people who never agreed to be in your post.
This app uses on-device face detection to batch-blur photos so you can share with less exposure of other people's faces.

Key features

- Automatic face detection (frontal and partial side angle)
- Batch blur multiple photos at once
- Per-face control: choose which detected faces to leave visible
- Ink-tone polaroid mosaic with a softer look
- Keeps saved photos from turning sideways
- Saves results as new photos to your gallery
- All processing runs on your device, no server upload

Use it before

- Posting group photos, parties, or gatherings to social media
- Sharing pictures that include strangers in the background
- Protecting children or family members in shared photos
- Uploading to buy-and-sell apps, blogs, or community forums
- Sending photos through messengers

How it works

The app uses on-device face detection to locate faces and applies a mosaic blur to those areas. Photo files never leave your device.

Notes

- Android 9 (API 28) and above.
- Side profiles, partial faces, or heavily occluded faces may not be detected. The result screen is being extended to let you add missing regions manually.
- Some social platforms re-compress your photos on upload, but they do not blur faces for you. Cleaning the photo before sharing is a separate step.
- Face mosaic is not a security tool. It does not guarantee that an already-shared photo cannot be reconstructed — it is designed for cleaning before you share.
