Convert PNG to Aseprite (.ase)

Open a PNG in your browser and save it as an .ase file that Aseprite opens, keeping layers and frames if you build them. No account required.

Open BitRasterFree, runs in the browser, no account needed.

How

  1. Open BitRaster and drag your PNG onto the canvas.
  2. Draw, add layers or add frames if you want more than the flat image.
  3. Export → Aseprite file, and save the .ase.

Worth knowing

The .ase is written to Aseprite’s own format rather than something that merely imports into it, so layers and frames arrive as layers and frames. A flat PNG in gives a single-layer, single-frame file out, which is the honest result.
