Sprite Sheet Generator
Convert any video or GIF into a game-ready sprite sheet in seconds.

Traditional sprite sheet workflows involve downloading desktop software, configuring complex settings, and waiting for batch processing. I Love Sprites eliminates all of that by running directly in your browser. Whether you're an indie developer prototyping animations, a technical artist iterating on sprite sequences, or a game jam participant who needs fast results — you get a professional-grade sprite sheet generator with zero setup, and your files never leave your machine.

The most common starting point is a rendered animation: a Blender turnaround, an After Effects export, a screen capture of a VFX loop, or an animated GIF from your artist. Upload it, pick a frame rate, and the tool extracts frames with FFmpeg compiled to WebAssembly — the same decoder used in production pipelines, running locally. From there you control scale (25%–200%), a frame cap (up to 256), padding between cells, and whether the sheet is padded up to power-of-two dimensions for older GPUs and stricter engine importers.

Choosing an FPS is a size-versus-smoothness trade. For UI effects and simple loops, 8–12 FPS usually reads fine and keeps the sheet small. Character animation typically wants 12–24 FPS. Only go to 30–60 FPS when the motion genuinely needs it — every extra frame is texture memory on the player's device. Because the preview plays back at your chosen rate before you export, you can find the lowest FPS that still looks right instead of guessing.

Export produces a packed PNG plus metadata in the format your engine expects: Unity, Godot, Phaser, PixiJS, Spine, Starling XML, CSS, or generic JSON with per-frame coordinates. If your source is a folder of individual images rather than a video, use the atlas packer instead — it accepts mixed sizes and packs them with MaxRects.
