About Spritesheet Generator
Spritesheet Generator is a free, browser-based tool for building game sprite sheets. Users upload PNG, JPG, GIF, WebP, or JSON files, or a single packed sheet that the tool splits into frames. They can arrange frames on a grid, edit pixels, recolor, preview the animation at a chosen frame rate, and export. The homepage says no signup is required.
Packing, recoloring, and export run locally in the browser. The homepage says nothing uploads unless the user publishes to the gallery. The tool works in Chrome 90+, Firefox 88+, Safari 14+, and Edge 90+, and older builds may break layout or export. The homepage gives a practical sheet size of about 8192x8192, which depends on the user's GPU and is not enforced. Polygon packing, sprite rotation during packing, multipack across several sheets, per-frame durations, and command line export are not supported.

Spritesheet Generator FAQ
Does my data leave my browser?
Packing, recolor, and export run locally. Nothing uploads unless you publish to the gallery.
What is the largest sheet size?
About 8192x8192 is a practical ceiling, not an enforced one. The limit depends on your GPU, so the homepage advises staying under it for sheets headed into an engine.
