Loop FX — Seamless Sprite Sheet Maker

Eight looping effects for 2D games. Adjust the colors, particles and timing, then export a transparent PNG sprite sheet.

The browser demo exports at 64 px per frame. The $2 download includes:

• The offline tool, with 64–512 px frames.
• Embers, snow, rain, motes, orbit, bubbles, stars and confetti.
• 24 ready-made sheets, plus editable presets.
• PNG sheets, optional individual frames and animation JSON.

Extract the ZIP and open index.html in desktop Chrome. No installation or account needed. Tested on Windows.

Import PNGs as a grid using the included dimensions and FPS. JSON is metadata, not an engine plugin. Effects loop in time; they do not necessarily tile in space. Preview backgrounds are not exported.

Commercial use in games and videos is included. Standalone resale of the tool or exported asset packs is excluded. See LICENSE.txt.
