About Make Sprite Sheet
Make Sprite Sheet is a browser-based utility for assembling, splitting, and converting 2D sprite sheets locally without uploading files to a server.
It supports packing up to 256 PNG, WebP, or GIF frames (up to 20 MB per file) into a grid layout, adjusting columns, padding, and spacing, previewing frame-by-frame animations at custom FPS, and exporting a transparent PNG sprite sheet alongside a JSON atlas compatible with 2D game engines such as Godot, Unity, and Phaser. It also includes tools for converting animated GIFs into sprite sheets and splitting existing sprite sheets back into individual frames.
