About Pixel Rumble

What it is

Pixel Rumble covers the small jobs that come up again and again when you work with pixel art: drawing a sprite, turning a picture into pixels, cutting a sprite sheet into frames, packing frames back into a sheet with an atlas, finding the exact colours of a classic console, and making an animated GIF. Each tool does one job, opens instantly and works on phones as well as desktops.

How it works

Everything happens in your browser. Images you open are decoded, edited and saved by the page itself, using your device's processor; they are never uploaded, and once a page has finished loading it keeps working without a connection. The editor keeps your current drawing in your browser's local storage so it survives a reload. There are no accounts, cookies or ads; page views are counted with Cloudflare Web Analytics, which uses no cookies and never sees your images (see privacy).

The palettes come from the sources named on the retro palettes page, and the dithering and colour reduction methods are the published ones named on image to pixel art. Animated GIFs are written with the open-source gifenc library and ZIP files with fflate.

What it is not

It is not a full painting program: there are no layers, brushes or animation timeline. For long projects a desktop editor such as Aseprite, LibreSprite or GIMP will serve you better, and the palettes and sheets you make here open in all of them.
