Pixelate image

Turn a picture into blocks to hide a face, a plate, or text, or for a pixel-art look. Free, with no upload.

Files stay on your device

Drop images to pixelate

Add one or as many as you like. Each is edited on your device, so nothing is uploaded.

PNG, JPG, WebP, HEIC, AVIF, SVG, BMP, and GIF. As many as you like, or a whole folder.

Pixelate
Every picture you add is saved with these settings.

Over the saved size. A face about three blocks across can't be made out.

Every color becomes the gray of how bright it looks.

Resize by

Shape

The whole picture is kept.

Turn

Clockwise above zero. The corners it leaves are filled in, or see-through in a PNG.

Mirror

Horizontal swaps left and right, as a mirror does. Vertical turns it upside down.

A JPG, PNG, or WebP stays what it is. Other pictures become JPG, or PNG when they're see-through.

How to pixelate an image online

Add a picture, choose how large the blocks are, and the whole picture is drawn in squares of that size. To pixelate only one part, crop to it first under Crop. The result is saved right away for download, in your browser, so your picture is never uploaded.

  1. Step 1

    Choose your pictures
    Add one picture, several, or a folder.

  2. Step 2

    Set the blocks
    Pick how many pixels across each block is.

  3. Step 3

    Download
    Save each pixelated picture, or all of them in a ZIP.

What to expect

Supported inputs
JPG, PNG, WebP, HEIC, AVIF, BMP, GIF, and SVG, one or many at once. HEIC opens in Chrome, Edge, and Safari on most computers, but not in Firefox.
What happens
Each block takes the average color of the pixels under it, so detail is gone rather than blurred, and the picture keeps its size. Larger blocks hide more. The picture is pixelated after any crop, turn, or resize, over the saved size.
Limits
The whole picture is pixelated; crop to a part first to pixelate only that part. Blocks of 8 pixels or fewer can still leave a face recognizable in a large picture.

Questions

Large enough that the face is about three or four blocks across. For a face 200 pixels wide, that's blocks of 50 or more.

Crop to that part under Crop, pixelate it, and paste the result over the original in any editor. Pixelating a chosen area in place is coming.

With blocks larger than the letters, yes: the colors are averaged, and the letters can't be read back out. Very small blocks can leave them readable.

No. They're pixelated in your browser, on your device, so nobody else sees them.
