About this photo-to-pixel converter
This turns a photograph or a piece of high-resolution art into pixel art: it reduces the resolution, cuts the colour count down to something a sprite palette can hold, and dithers the result so gradients survive the reduction instead of banding.
A straight downscale in an image editor gives you a small blurry photo. The difference here is the colour quantisation and dithering happening together, which is what makes the output read as pixel art rather than as a thumbnail.
How to use it
Load an image. Set the output width and height, with the aspect-ratio lock on if you want it kept in proportion.
Choose a dither: none for flat blocks, ordered 4 × 4 Bayer for a regular cross-hatch, or Floyd–Steinberg for a softer scattered look.
Reduce to a set number of colours with median-cut, snap to a preset palette, or paste your own hex list.
Optionally add a 1px outline around the opaque regions to give the sprite a defined edge.
Compare before, after and side-by-side, then export.
Formats and options
Export at true size (1×) or scaled 2×, 4×, 6×, 8×, 12× or 16× with hard edges.
Send the result straight into Pixel Art Studio to clean it up by hand.
Custom palettes are accepted as a plain hex list, so a palette exported from Palette Studio drops straight in.
Everything is processed on a canvas in your own browser — the image is never uploaded.
