About This Tool

The tool provides a focused environment for composing sprite sheets by arranging frames in a grid, assigning tile colors or importing tiles from existing images, and exporting a sprite atlas.
Conceptually, it treats a sprite sheet as a collection of equally sized frames laid out on a canvas. You specify sheet dimensions and tile size, then place frames in a grid, with optional padding. It computes frame coordinates and exports: a sprite atlas image and a JSON atlas with coordinates and sizes.
Beneficiaries include game developers and pixel artists who need precise frame ordering and atlas exports. Unique value lies in being lightweight, offline-capable, and tailored to sprite workflows rather than full image editing.
Core features include grid editor, simple palette or tile import, frame indexing, padding controls, and export options. Use cases cover character animations, UI sprites, and tile-based assets.
Outputs are readily consumable by game engines and animation pipelines, reducing integration time and tool-switching.

Add or import tiles and place frames on the grid.
Arrange frames in the desired order and verify coordinates.
Export atlas image (PNG) and atlas data (JSON).
Validate alignment in your engine and iterate if needed.

Frequently Asked Questions

Find Quick Answers

What export formats are supported?

Exports include a PNG atlas image and a JSON atlas describing frame coordinates, sizes, and ordering. The JSON schema can be adapted to common game engines and runtime parsers.

Can I import existing sprites or sprite sheets?

Yes. You can import a sprite strip or a set of frames, then remap them to a grid by matching tile size and padding. The tool parses the input into individual frames for reordering and re-export.

Is the tool browser-based and offline-capable?

All processing is client-side in modern browsers. No data is uploaded to servers, and the editor works offline after initial load, making asset work predictable in isolated environments.

Does it support animation preview?

The editor focuses on layout and atlas export; it provides frame ordering and coordinates suitable for animation pipelines but does not render runtime playback. You can verify sequence in your engine with the exported data.
