Why hide it?
Shipping labels in resale photos, strangers' faces in group shots, addresses or account numbers in proof photos — once they're online, they're hard to take back. Reliably masking sensitive areas before posting is the safest protection.
Gaussian blur vs mosaic
A Gaussian blur smears edges for a natural look, but applied lightly the original may still be faintly visible. A mosaic covers the area with large pixels that firmly block recognition. For text or numbers (plates, addresses, card numbers) that must not be recoverable, use a mosaic or a strong blur.

- Paint slightly wider than the target to cover the edges
- Use a mosaic — not a light blur — for text and numbers
- Raise the intensity enough that the shape is gone
- After saving, zoom into the result to confirm nothing shows
After you blur
The result is saved as a PNG, and the hidden information can't be recovered from the downloaded file. If you're posting to social media or a blog, shrink it first with the image compressor for a faster upload.
