3DS Converter
FileFlip converts 3DS files into 13 other formats entirely inside your browser, using Assimp compiled to WebAssembly. The 3DS 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 a 3DS file?#
- Drop your 3DS 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 3DS files online?#
Yes, because nothing is uploaded. FileFlip converts 3DS 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 a 3DS file?#
A 3DS file is the binary, chunk-based scene format of Autodesk's 3D Studio DOS, released in 1990, storing mesh, texture and lighting data behind two long-standing limits: 65,536 vertices per mesh and 8-character names.
Use 3DS only when the destination is legacy software that specifically expects the format, since its limits make it a poor choice for anything new.
Convert 3DS to OBJ or FBX to get past the vertex and naming limits, or whenever the model needs to sit in a modern pipeline.
The 3DS file format reference covers the specification, the programs that open one, and what each conversion keeps or drops.
3DS questions people ask#
What is a 3DS file?
A 3DS file is the native scene format of Autodesk's 3D Studio DOS, released in 1990, storing mesh geometry, texture references and lighting in a binary, chunk-based structure. It's still widely found in older asset libraries because so much content was authored in that era.
Why won't my 3DS file open with all its vertices?
The 3DS format has a hard limit of 65,536 vertices and faces per mesh, dating back to its DOS-era design. A model that exceeds that has to be split into multiple meshes before it's saved as 3DS, or the excess geometry gets cut or corrupted.
Is 3DS the same as 3ds Max's native format?
No. 3DS was 3D Studio DOS's format, but 3ds Max, its successor released in 1996, uses a different native format, .max, that has none of the old vertex or naming limits. 3DS survives today mainly as an interchange format rather than any current application's native one.
Can 3DS store textures?
Yes, a 3DS file can reference texture maps for its materials, though texture filenames are restricted to the old 8.3 DOS naming convention. Material names are capped at 16 characters, which can truncate names coming from a modern export.
