QUICK ANSWER
Is it possible to convert ASEPRITE to ASE?
No - not a direct conversion.

Aseprite's native format ships with two interchangeable extensions: .aseprite and .ase. They store identical data (layers, frames, palette, tags, slices), so a "conversion" is really just renaming the file or choosing .ase in the Save As dialog. The only reason both exist is that Adobe already uses .ase for Swatch Exchange files, which can cause confusion.

Why convert ASEPRITE to ASE?

People look for this because they see both extensions and assume they differ. In reality Aseprite treats .ase and .aseprite as one and the same native format, and the developers added .aseprite purely to avoid clashing with Adobe's unrelated .ase swatch files.

How to convert ASEPRITE to ASE

Rename the file EASIEST

Since the bytes are identical, just rename sprite.aseprite to sprite.ase in your file manager. Aseprite opens either one the same way.

Save As in Aseprite

Open the file and use File > Save As, then type a name ending in .ase. Aseprite writes its native format under whichever of the two extensions you choose.

LibreSprite Save As FREE

In the free fork LibreSprite, open the sprite and pick File > Save As with an .ase name to write the same native format.

Quality & what to watch

  • No data is lost or changed - the file content is byte-for-byte the same regardless of which extension you use.
  • Don't confuse Aseprite's .ase with Adobe's .ase (Swatch Exchange); they are unrelated formats that share an extension.
  • Some older tools and importers only recognize one spelling, which is the only practical reason to switch.

Frequently asked questions

Is `.ase` different from `.aseprite`?
No. Both are Aseprite's native format and contain identical data; the extension is the only difference.
Why does Aseprite offer two extensions?
Adobe uses .ase for its Swatch Exchange files, so Aseprite added .aseprite to avoid confusion.
Can I just rename `.aseprite` to `.ase`?
Yes. Renaming is safe because the file format is exactly the same.
Will other programs open my `.ase` sprite?
Only Aseprite, LibreSprite, and a few importers read this format; general image viewers cannot open it.
