Block pixelation
This tool lets you pixelate an image by resampling it into solid, single-color blocks. It is ideal for censoring faces, hiding text, or creating retro 8-bit graphics. The pixelate effect runs entirely in your browser, keeping your files private on your device.
To pixelate an image, simply adjust the block size from fine pixel textures up to massive, abstract squares. The preview updates live, and the downloaded file keeps your original image format and full resolution.
Retro color palettes
By default, the tool uses the original colors of your photo. To create a true vintage aesthetic, limit the colors to a historical hardware palette. Options include classic 4-color Game Boy, PICO-8, Commodore 64, EGA, and ZX Spectrum configurations.
When using a limited palette, Dither Amount scatters pixels near color boundaries to simulate gradients without adding more colors. This turns smooth photographic shading into patterned dots, which is essential when you pixelate a photo into strict 8-bit or 16-bit color limits.
Blending and censoring
Pixel Size controls the severity of the pixelation. A size between 8–20px creates a clear pixel-art look, while sizes above 24px destroy recognizable detail, making it perfect for censoring sensitive information.
Effect Strength allows you to blend the chunky blocks back into the original photo. Lowering the strength lets some of the underlying detail show through the grid, creating a textured overlay rather than a complete abstraction. If you only want to censor a specific part of an image, crop that region first, apply the effect, and composite it back later.
