Aseprite File Compatibility

Use .aseprite or .ase to exchange pixel-art projects with Aseprite. Import converts supported content into a .resprite project; export creates an Aseprite copy. Keep the source file and the editable Resprite original when moving between apps.

Importing .aseprite files

Choose Aseprite in Import Artwork, then check the converted layers, animation, and clips. Frame durations recorded in milliseconds are retained and converted into Resprite frame timing. Review or adjust them in Frame Properties.

Content	Import result
Image layers	Supported pixels, opacity, and blend modes are converted.
Layer groups	Group opacity becomes full opacity and group blend mode becomes Normal. Image-layer properties are handled separately.
Animation tags	Converted into non-overlapping clips. Overlapping tags need adjustment; check names and boundaries.
Playback direction	Ping-pong Reverse becomes standard Ping-pong. Tag repeat counts are not retained.
Linked cels	Links compatible with Resprite's inheritance chain can stay inherited; others become independent pixel cels.
Palette and indexed pixels	Pixels are resolved through the palette into full-colour pixels. Palette colour names and indexed editing relationships are not retained.
User Data, Slice, and Tileset chunks	Skipped. Aseprite tilemap content is not imported as a native tilemap or automatically rasterized by this workflow.

Use Tiled maps and tilesets when you need to exchange editable maps.

Exporting .aseprite files

Export a copy through the Aseprite entry in the export menu. The result is subject to these conversion limits:

Content	Export result
Group opacity and blending	Not preserved as equivalent editable group behaviour. Compare the grouped result in the destination app.
Clipping masks	Not retained as equivalent editable relationships.
Live layer styles	Stroke, Shadow, and other styles are skipped; they are not automatically baked into pixels.
Tilemap layers	Rendered as ordinary pixels, without tilemap structure or tileset resources.
Reference images	Omitted.
Palette layout	Colours are compacted; Resprite palette-grid positions are not retained.
Grid settings	Isometric grid settings are omitted. Regular grid dimensions are omitted when the grid is disabled.
PinLight blending	Converted to Normal.

These are Resprite conversion limits. A format's ability to represent a property does not guarantee that the exchange preserves it.

Check a copy before continuing

1. Save the .resprite original and export a copy.
2. Reopen the result in the destination app.
3. Compare layer and group appearance, clipping, frame timing, and clip ranges.

If a live style must be visible in the output, duplicate the project and rasterize the style in that copy before export. To exchange one layered frame, consider PSD and its separate compatibility limits.
