From subtle texture to full mosaic
Pixelation is scale: at 6–10 px it reads as a stylish texture, at 20–40 px it becomes the classic censor mosaic,
and at 60+ the image turns into abstract colour blocks — good for teaser reveals, retro game art and privacy-safe
thumbnails. The slider covers the whole range and the preview updates as you drag.
One honest note: to hide a specific detail — a face, a plate, an address — pixelate just that region with the
Image Redactor, and prefer its solid blackout for anything truly sensitive, since
heavy pixelation is hard to reverse but blackout is impossible.
Frequently asked questions
Pixelate the whole image or just part of it?
This tool pixelates the whole image — the retro-mosaic look. To hide just a region, like a face or an address, the Image Redactor lets you paint pixelation exactly where you want it.
Is pixelation safe for hiding sensitive information?
For genuinely sensitive content use solid blackout (in the Image Redactor) instead: heavy pixelation is hard to reverse, but blackout is impossible, and that certainty is worth having.
Most online converters upload your file to a server. InfyTool ships the actual encoders to your browser as WebAssembly instead, so processing happens inside your tab — faster for batches, and nothing to delete afterwards.
No upload, ever. Turn off Wi-Fi after the page loads and every tool keeps working.
No limits. No file-size cap, no queue, no watermark, no account.
