Pixelate an image online

Runs in your browser — this file is never uploaded

Turn fine detail into big, blocky squares — the classic way to obscure a face, a licence plate, or a screen in a screenshot. Add your images, choose how coarse, and download the result.

This works the way pixelation always has: the image is shrunk down until each remaining pixel represents a whole block of the original, then scaled back up with no smoothing, which is what keeps the block edges hard rather than blurring back into a gradient.

Your images never leave your device. Pixelating runs entirely in your browser, so nothing is uploaded, stored, or scanned, and a batch costs no more than a single file.

How to pixelate image

  1. Add your images

    Drop JPG, PNG, or WebP files into the box, or click to browse.

  2. Choose how coarse

    Larger blocks obscure more completely but destroy more of the surrounding picture too.

  3. Pixelate and download

    Press Pixelate Image. One file downloads on its own; several arrive as a ZIP.

Frequently asked questions

Are my images uploaded anywhere?

No. Pixelating runs in your browser using JavaScript, so your files stay on your device. You can confirm this by opening your browser devtools Network tab while working — there are no upload requests.

Can I pixelate just one area, like a face?

This tool applies to the whole image evenly. If you only need one region obscured, crop that region out first with Crop Image, pixelate the crop, and re-combine it in an editor — this tool does not offer local selection.

Is a pixelated face or plate actually unreadable?

At a large block size, yes — the detail is genuinely destroyed and cannot be reversed back into the original pixels, unlike a light blur which can sometimes be partially undone. Use a large block size for anything you actually need hidden, and check the result at full size before you rely on it.

How is this different from Blur Image?

Blur softens detail gradually and evenly; pixelation replaces it with hard, uniform squares. Pixelation is the more common choice specifically for hiding identity, since the blocky look reads unambiguously as "redacted" rather than just out of focus.

Is there a limit on how many files?

Thirty at a time, which is a limit of your device rather than our policy — everything is held in memory while it works.
