Replace fine image detail with a grid of visible square color blocks. The browser first reduces the image to a small sampling canvas and then enlarges it without smoothing, creating a true block effect while keeping the original dimensions.
How to use Pixelate Image
- Choose a JPEG, PNG, or WebP image.
- Set the pixel block size and choose an output format.
- Process the image, review the block effect, and download the pixelated copy.
Things worth knowing
- Larger blocks hide more detail and create a stronger effect.
- The output width and height match the source.
- Pixelation can obscure incidental detail, but it should not be relied on to anonymize sensitive information that must be irrecoverable.
Frequently asked questions
What block size should I use?
Start around 16 to 32 pixels for a typical photo, then increase the size when you need a stronger effect.
Does pixelation reduce the image dimensions?
No. A small canvas is used during processing, but the final file is restored to the source dimensions with crisp square blocks.
