Best practices for better results

Image optimization works best when you choose the right balance between file size, visual quality, dimensions, format compatibility and privacy. These tips help you get a cleaner result.

  • Start from the original image whenever possible.
  • Review the output before publishing or deleting your original file.
  • Use related tools like resize, convert or metadata removal when you need a more specific result.
  • Choose the right format for the job: JPEG for photos, PNG for sharp graphics and WebP for modern websites.

Pixelate photos into blocky pixel art

The Pixelate Image tool turns a normal photo into a blocky mosaic-style image. Increase the pixel size for a stronger retro look, or keep it subtle when you only want to obscure details.

Common uses

  • Create pixel art-style profile images and thumbnails
  • Blur or hide sensitive details in a screenshot
  • Make retro graphics for posts, memes and design mockups
  • Turn photos into chunky mosaic-style visuals
Tip: Smaller pixel sizes keep more detail. Larger pixel sizes create a stronger blocky effect.
