Questions about Photo Mosaic & Blur

Is pixelation reversible?

Strong pixelation averages each block into one colour, destroying the original detail, so it cannot be undone from the output. Use a coarse block size for sensitive data; light blur can sometimes be enhanced, so prefer pixelation for faces and plates.

Are my photos uploaded?

No. The image is drawn and edited on a canvas entirely in your browser, and the PNG is generated locally. Nothing is sent to a server.

About Photo Mosaic & Blur

Pixelate or blur faces and sensitive areas with our free online Photo Mosaic & Blur. 100% browser-based, fast, and private—no login or file uploads required.

These image tools handle everyday photo jobs: compress and convert between JPG, PNG and WebP, resize to exact pixels, build QR codes and favicons, pick colours and assemble animated GIFs.

This tool runs in your browser. The file is not uploaded. For photos prefer JPG or WebP at a sensible quality; keep PNG for logos and screenshots with sharp edges or transparency, since JPG would blur them and drop the alpha channel.
