Pixel Quantizer

Pixel Quantizer 64 — React Edition
Free, offline, browser-based pixel art lab. Originally a Unity EditorWindow, now rewritten in React + Tailwind.

Drag in any PNG/JPG/WEBP and instantly get a crisp, Point-filtered 64x64 (or 4-128) sprite mapped to a custom 28-color palette. No server, no upload — everything runs in your browser.

This build is entirely in HTML5 and based on a Unity prototype.

If you would like me to update and expand this file please consider donating.

Let me know in the comments what desired improvements or bugs you experience and we will update it for Version 2.

The Pixel Quantizer is free to use and generate your own pixel art for your own projects, if you would like to purchase the zip file you can use the source code to the quantizer itself in your projects.
