Pack existing artwork into a single atlas
An atlas combines separate frames into one image, with coordinates that identify each frame. It organizes artwork you already have. It does not create missing poses or infer an animation from unrelated pictures. Use GIF to sprite sheet when the source is an existing GIF, or the sprite sheet viewer when you already have an atlas and need to split or preview it.
Check the order before exporting
File names such as walk-1, walk-2 and walk-10 should follow their intended numeric sequence. Review the frame order instead of assuming upload order matches playback. A common frame box keeps character placement stable; images with different canvas sizes may otherwise appear to jump. Transparent padding leaves breathing room between frames without changing the subject.
This release creates a uniform grid
A regular grid is straightforward to inspect and split. Compact packing can reduce unused area, but the consumer must read frame coordinates rather than assume equal cells. This version exports a uniform grid; compact packing is not offered. Export metadata together with the sheet and check the output image dimensions against your target renderer’s texture limits.
Images do not contain animation timing by themselves
Separate PNG or JPEG frames do not specify how long a game should display them. Set timing in your animation code or destination tool and inspect the sequence before publishing. This free packing workflow stays local. AI-generated action frames are a separate mode and should only be treated as available when its controls and billing are enabled.

Frequently asked questions
What does a sprite sheet generator do?
It arranges existing images into one atlas and exports coordinates for the frames. It does not invent artwork or missing movement poses.
How should I name animation frames?
Use a consistent numeric sequence and review the order in the tool. Natural sorting can keep frame 2 before frame 10.
Should I use a grid or compact packing?
This version creates a uniform grid for simple cells and splitting. Compact packing is not offered.
Can I pack transparent frames?
Use a source format with transparency, such as PNG, and inspect the output background. JPEG files cannot supply transparent pixels.
Does packing images create an animated file?
The atlas is a static image containing many frames. Playback requires animation code or a viewer that uses the frame coordinates and timing.
