What is the Pixelate Image?

The ByteTools Pixelate tool reduces an image to blocky squares of a size you control. It works by shrinking the picture and scaling it back up with smoothing turned off, giving a crisp mosaic look rather than a soft blur.

  • Adjustable block size from fine to heavily blocky
  • Crisp mosaic pixels, not a soft blur
  • Great for censoring faces and sensitive details
  • Retro pixel-art style at large block sizes
  • Live preview updates as you drag
  • 100% private — images never leave your browser

About the Pixelate Image

The ByteTools Pixelate tool reduces an image to blocky squares of a size you control. It works by shrinking the picture and scaling it back up with smoothing turned off, giving a crisp mosaic look rather than a soft blur.

Use it to censor faces, license plates or sensitive details before sharing a screenshot, or to give artwork a deliberate retro, 8-bit style. The larger the block size, the chunkier and more abstract the result.

The whole effect is computed locally on an HTML canvas in your browser. Your image is never uploaded, so private photos and screenshots you want to redact stay entirely on your device.

Frequently asked questions

How do I pixelate an image?

Upload the image and drag the block size slider until the detail you want to hide is no longer readable, then download the PNG. Larger blocks produce a chunkier, more censored look.

Is pixelating a face enough to hide someone's identity?

Use a large block size so the features are completely unrecognizable. Very light pixelation can sometimes be reversed, so make the blocks big enough that no facial detail remains before you share the image.

What is the difference between pixelate and blur?

Pixelation replaces areas with solid square blocks for a crisp mosaic, while blur smears pixels into a soft haze. Pixelation is usually preferred for censoring because it removes fine detail more decisively.

Are my images uploaded when I pixelate them?

No. The pixelation is performed in your browser using the canvas API, so nothing is sent to a server. This makes it safe for redacting private or sensitive screenshots.
