Pixelate an image or a region online to censor a face, blur out sensitive text, or create a retro mosaic effect. Pixelation replaces detail with coarse blocks, permanently obscuring what was there.
Censor faces and sensitive details safely
Pixelation replaces detail with coarse blocks and, used with a large enough block size, permanently removes the underlying information — unlike a light blur, which can sometimes be reversed. Use a coarse setting to hide a face, licence plate, name, or address before sharing, and keep the original separate.
Or a deliberate retro look
Smaller blocks give a stylised, 8-bit mosaic effect for creative use. Either way you preview the result and choose the block size. Your image is uploaded to do the work and deleted automatically an hour later.

Frequently asked questions
Is pixelation safe for hiding private information?
Used with large enough blocks it permanently removes the underlying detail, unlike a light blur. Use a coarse block size for anything sensitive, and keep the original separate.
Can pixelation be reversed?
No — the detail is discarded, which is why it is suitable for censoring.
Is my image uploaded?
Yes — your image is uploaded so our server can do the work, and it is deleted automatically an hour later. No account is needed.
