"Casually forwarded a chat screenshot, didn't expect to leak a friend's info." This happens every day. Search WeChat, Twitter, or any social platform and you'll find countless screenshots with unmasked names, avatars, phone numbers, and amounts. Pixelating before sharing isn't a hassle — it's basic etiquette and the bottom line for protecting yourself and others.
What Must Be Pixelated
Before posting any screenshot, check these five categories:
- Names/nicknames — real names and WeChat handles
- Avatars — recognizable at a glance, must blur
- Phone numbers/WeChat IDs — prime targets for spam
- Amounts/transfers — financial information
- Locations/addresses — a safety concern
Which Blur Method to Use
| Method | Effect | Best for |
|---|---|---|
| Mosaic | Pixelated block | Avatars, faces, standard info |
| Blur | Gaussian blur | Amounts, text-dense areas |
Mosaic suits small areas (avatars, single words); blur suits large or text-dense regions. The tool supports both — choose per use.
How to Pixelate a Screenshot
Open the PixelForge Mosaic tool:
Step 1: Upload the screenshot — batch supported.
Step 2: Select the regions to pixelate — drag rectangles over sensitive info.
Step 3: Choose mosaic or blur — tune intensity; the more sensitive, the stronger.
Step 4: Confirm and download — check for gaps before saving.
Three Screenshot Tips
- When in doubt, pixelate — if unsure whether info needs masking, mask it. There's no undo after posting
- Use high intensity — names and avatars need the strongest mosaic to prevent reconstruction
- Check before posting — zoom in and confirm nothing is readable before sending
Common Mistakes
- Region too small — mosaic blocks must be large enough that outlines aren't visible
- Text masked, avatar not — an avatar leaks identity just as much
- No final check — many incidents come from one missed item after "masking"
