About
Pixelation is useful for more than just censoring — it can give your GIF a retro 8-bit look, hide sensitive details, or create an eye-catching glitch aesthetic. Adjust the pixel block size to go from a subtle mosaic to full-on chunky pixels across every frame of your animation.
Features
Adjustable pixel block size lets you dial in exactly the right amount of pixelation
The effect is applied uniformly across every frame for a consistent look
Works great for both full-frame retro effects and targeted area censoring
Runs entirely in your browser so your files stay private

Pro Tips
For a retro gaming aesthetic, use large pixel blocks (8-16px) on the entire GIF
Smaller block sizes (2-4px) work better for subtle anonymization of faces or text
Try pixelating first and then adjusting speed — the combo can create interesting visual effects
