ASE Converter
FileFlip converts ASE files into 14 other formats entirely inside your browser, using Assimp compiled to WebAssembly. The ASE file is never uploaded to a server: it is read off your disk, converted on your own machine, and saved back by the browser. There is no file-size limit and no account to create.
How do I convert an ASE file?#
- Drop your ASE file onto the converter at the top of this page, or click it to pick one from your computer.
- Choose the format you want out of it. FileFlip downloads the engine that conversion needs, once, and your browser caches it.
- Conversion starts the moment you pick the format, and the result is yours to download. The work happens in this tab, so nothing is uploaded and nothing is queued.
Is it safe to convert ASE files online?#
Yes, because nothing is uploaded. FileFlip converts ASE files inside the browser tab you already have open, using WebAssembly builds of the same engines a desktop converter would install. Your file is read from your own disk into the page's memory, and no request carrying it is ever made.
You do not have to take that on trust. Open your browser's network panel, run a conversion, and you will see the engine come down and your file go nowhere. There is no upload, no server-side copy, no retention window, and no account tied to what you converted.
How FileFlip works lists every engine, its version and its download size, and shows how to check for yourself that nothing leaves your machine.

What is an ASE file?#
An ASE file is 3ds Max's ASCII Scene Export, a plain-text dump of a scene's meshes, materials, cameras, lights and keyframe animation, written to be easy for another program's importer to parse.
Export ASE when a target tool's importer specifically expects it, which in practice means an older or custom game-engine pipeline.
Convert ASE to FBX or glTF for any pipeline built after FBX became 3ds Max's standard interchange format.
The ASE file format reference covers the specification, the programs that open one, and what each conversion keeps or drops.
ASE questions people ask#
What is an ASE file?
An ASE file is 3ds Max's ASCII Scene Export, a text file listing a scene's meshes, materials, cameras, lights and keyframe animation. It was designed so a game engine or another tool could write a straightforward text parser for it rather than needing 3ds Max's binary SDK.
Can 3ds Max open an ASE file it previously exported?
Not directly. 3ds Max ships an ASE exporter but no matching importer, so getting an ASE file back into Max requires a MAXScript or a third-party plugin rather than File, Import.
Is ASE still used instead of FBX?
Rarely for new work. ASE was the common way to move 3ds Max scenes into game engines before FBX became the standard interchange format, and it mainly still turns up in older pipelines or tools whose importer was written specifically for it.
