About Image Pixelator

Image Pixelator is here for editing a picture one job at a time: mosaic/blockate areas or the whole image. It takes JPG, JPEG, PNG and 9 more and produces JPG, JPEG, PNG, WEBP. If a run goes wrong there is nothing to chase: no job sitting on a server, no upload to ask anyone to delete.

Useful when the job is editing a picture one job at a time and you would rather not install software, join a queue or hand the file to a stranger.

How to use Image Pixelator in 3 steps

  1. Drop the image onto the drop area, or several at once up to 50 files.
  2. Set the Block size in pixels.
  3. Press Apply Pixelate and download the result in whichever of JPG, JPEG, PNG, WEBP suits you.

Image Pixelator: questions

Which file types does Image Pixelator accept?
The drop area takes JPG, JPEG, PNG and 9 more. Files are read from your device in the browser, so the format has to be one a browser can decode — that is why the accepted list on this page is finite and honest rather than "everything".
What do I get back from Image Pixelator?
The result is JPG, JPEG, PNG, WEBP, offered as a download the moment the work finishes. Multiple results come back together rather than as fifty separate save dialogs.
Can I process several files at once?
Yes, up to 50 files in a batch, each no larger than 100 MB. Results come back together instead of one save dialog per file.
Is it safe to use for a document with personal details in it?
That is the design goal: the document stays on your device, so a statement, a contract or an ID photo is never transmitted for processing. Nothing here needs an internet connection once the page has loaded, apart from engines that fetch their own model data.
