What Does Pixelating an Image Do?
Pixelation replaces fine image detail with large colored squares — like the graphics from classic video games. It's a popular technique for:
- Censoring sensitive content in screenshots or documents
- Hiding license plates in street photography
- Creating retro pixel-art effects for creative projects
- Protecting anonymity in public photos
Pixelate vs. Blur — What's the Difference?
| Feature | Blur | Pixelate | |---|---|---| | Effect | Smooth, soft edges | Hard-edged squares | | Best for | Faces, backgrounds | Text, numbers, license plates | | Reversible? | No | No | | App look | Subtle | Obvious censorship |
How to Pixelate an Image Online
- Open the Pixelate Image Tool
- Upload your image via drag-and-drop
- Select Pixelate mode in the tools panel
- Adjust the block size with the Blur Strength slider (higher = bigger blocks)
- Paint over areas to pixelate using the brush, or use Whole Image mode
- Download your result as PNG or JPEG
What Block Size Should I Use?
- 1–5: Very fine pixelation — barely visible, good for subtle effects
- 8–12: Medium pixelation — faces become less recognizable
- 15–20: Heavy pixelation — text and faces become completely unreadable
For censoring license plates and text, use a block size of 15 or higher.
