ASK Converter
FileFlip converts ASK files into 14 other formats entirely inside your browser, using Assimp compiled to WebAssembly. The ASK 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 ASK file?#
- Drop your ASK 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 ASK files online?#
Yes, because nothing is uploaded. FileFlip converts ASK 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 ASK file?#
An ASK file holds 3ds Max ASCII Scene Export text under an alternate extension; readers that support ASE, including Assimp, parse ASK with the identical parser because the file content is the same format.
Treat an ASK file exactly like an ASE file; there's no reason to prefer one extension over the other.
Convert ASK the same way you would ASE, to FBX or glTF, once the scene needs to leave whatever tool produced it.
The ASK file format reference covers the specification, the programs that open one, and what each conversion keeps or drops.
ASK questions people ask#
What is an ASK file?
An ASK file is 3ds Max ASCII Scene Export content saved with a .ask extension instead of .ase. It is not a separately specified format: every tool that reads ASE, including Assimp, reads ASK with the same parser because the text inside is identical.
Is ASK the same as ASE?
Functionally, yes. An ASK file uses the same ASCII Scene Export syntax as an ASE file, just under a different extension, and no published specification treats ASK as a distinct format.
What opens ASK files?
Anything that reads ASE opens ASK, since the two are handled by the same parser. 3ds Max can export the format but has no built-in importer for either extension, so reading one back in needs a script or plugin.
