Free Sprite Sheet Generator for Unity VFX

The VFX Flipbook Tool is a free online sprite sheet generator. It packs a PNG sequence into a single sprite sheet, slices an existing sprite sheet back into individual frames, converts black backgrounds to alpha, and shows the Unity settings needed to play the result. Everything runs in your browser, so your files are never uploaded.

How to make a sprite sheet from a PNG sequence

Export your effect as a numbered PNG sequence, for example fire_01.png to fire_32.png.
Drag all frames into the drop area on the PNG frames → Sheet tab. Frames are sorted by file name, so frame_2 comes before frame_10.
Keep Auto grid on, or set the columns and rows yourself. Use Use every Nth frame to thin out long sequences.

Set Start Lifetime to the value the tool calculates so the frames play once at your chosen FPS. The panel also lists matching settings for a Shader Graph Flipbook node and a VFX Graph Flipbook output, and you can copy them with one click.

How to split a sprite sheet into frames
