Pixelate Image
Pixelate any image online with adjustable pixel size and output dimensions. Create a mosaic effect and download as PNG - runs locally in your browser.
How it works
Upload an image, choose a pixel size, and the tool re-renders the image using large “blocks” to create a pixelation effect.
You can also set output dimensions, choose contain/cover fit, and download the final result as a PNG.
- Pixel size: Controls block size (bigger = more pixelated).
- Output size: Sets exported width/height in pixels.
- Fit mode: Contain preserves the full image; Cover fills the output (may crop).
Common uses
Pixelation is often used as a privacy-friendly alternative to blur, since it’s harder to reverse and keeps layout recognizable.
- Privacy: Hide faces, names, addresses, and IDs in screenshots.
- Design: Create stylized thumbnails, mockups, and retro looks.
- Quick edits: Apply pixelation without installing software.
