When sharing group photos, street shots, or travel pictures, there's a common dilemma: people in the photo don't want to be identified. Face mosaicing is the simplest, most effective privacy protection. Here's how to do it well.
When to use face mosaic
- Sharing group photos but not everyone wants their face shown
- Street photos with unfamiliar bystanders
- Sharing photos where someone requested anonymity
- Security reasons — not wanting yourself or family identified
Faces are among the most sensitive personal data. Mosaicing prevents recognition, misuse, and malicious use.
Mosaic vs blur
| Method | Effect | Use case |
|---|---|---|
| Mosaic | Pixelated, explicit | Clearly “privacy hidden” |
| Gaussian blur | Soft, natural | Low-key, aesthetic |
| Sticker overlay | Playful | Fun, decorative |
Mosaic clearly signals blocking; blur is more natural. For clear protection use mosaic; for nicer looks use blur.
How to mosaic a face with PixelForge
Open the PixelForge Mosaic Tool — all local, no upload (ideal for sensitive faces).
Step 1: Upload the photo.
Step 2: Drag to select the face area(s); multiple selections supported.
Step 3: Choose mosaic (adjust cell size) or blur (adjust intensity), preview, and export.
Tips
- Cover the full face — half-covered faces aren't protected
- Select every face — don't miss any
- Moderate intensity — too-fine mosaics can be reconstructed
- Keep originals — mosaicing is irreversible
