Free 3D file conversion for everyone
Convert3D was built with one simple goal: make 3D file conversion free and accessible to everyone. Whether you're a 3D artist, game developer, architect, or student — you should never have to pay just to convert a file format.
Unlike many other online 3D converters, Convert3D has no pricing page, no premium tiers, and no paid API plans. Every format and every feature is completely free — no catches.
Convert3D is a free online tool that lets you convert 3D files between different formats. We support over 20 popular 3D formats including FBX, OBJ, GLTF, GLB, STL, PLY, DAE, 3DS, and many more.
Our converter is powered by the Noesis engine — one of the most reliable and accurate 3D format conversion tools available. This means your models, geometry, materials, and textures are preserved with maximum fidelity during conversion.
All conversions happen on our secure servers and your files are automatically deleted after 1 hour. No account required, no fees, no limits.
The 3D industry uses dozens of incompatible file formats. Game engines prefer FBX or GLTF. 3D printers need STL. Some tools only accept OBJ. Converting between these formats used to require expensive software or complicated tools.
We believe conversion should be a simple, free utility — like any other online tool. So we built Convert3D to solve this problem once and for all.
Most files convert in under 10 seconds using our optimized server infrastructure.
Your files are never shared or stored permanently. Auto-deleted after 1 hour.
No pricing tiers, no premium plans, no paid API. Supported by advertising so every feature stays 100% free, forever.
We currently support conversion between the following 3D file formats:
