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
