Blurring faces before posting to social media, pixelating phone numbers in chat screenshots, hiding key info on ID documents… image mosaic (pixelation) is the most important step for privacy protection. But many people do it unsafely — covering with stickers or solid color blocks that are easy to recover. Here's how to pixelate properly with an online mosaic tool.
Why use mosaic instead of stickers
Many people use stickers or solid blocks to hide sensitive info, but that's actually insecure:
| Method | Security | Detail |
|---|---|---|
| Solid block / sticker | Low | Professional tools may recover via image algorithms |
| Blur | Medium | Strong deblurring may restore |
| Mosaic / pixelation | High | Info destructively scrambled, hardest to recover |
To really protect privacy, use mosaic (pixelation), not a simple sticker.
How to use an online mosaic tool
Using PixelForge Mosaic tool:
Step 1: Upload the image. Step 2: Paint over the areas to hide — faces, plates, phone numbers, ID numbers, etc. Step 3: Adjust mosaic strength — higher is harder to recover. Confirm coverage. Step 4: Download. Batch supported, fully local, free.
Common pixelation scenarios
- Face pixelation: protect yours or others' privacy when sharing photos
- License plate: hide plate numbers when posting car photos
- ID documents: hide numbers, addresses on uploaded ID images
- Phone numbers: hide numbers in shared chat screenshots
- Sensitive info: process privacy-related document screenshots
Pixelation tips
- Pixelate strongly: high strength to prevent recovery
- Cover completely: fully cover sensitive areas, no gaps
- Check before posting: review carefully for missed info
For highly sensitive files like IDs and contracts, use the strongest mosaic and a local-processing mosaic tool to avoid uploading to third-party servers.
