About Convert3D

An independent, one-person project for converting, viewing, and compressing 3D model files — built by someone who actually works with these formats.

Who built this

Convert3D is created and maintained by Huy Nguyen, a developer who has spent several years working directly with 3D file formats — moving CAD, game, and 3D printing assets between formats like STL, OBJ, STEP, FBX, and GLB. That day-to-day work with real conversion edge cases (broken normals, unit mismatches, unsupported material data) is what shaped how this tool handles conversions.

Huy Nguyen also built and runs MiConvert.com, another file conversion tool, so Convert3D reuses lessons learned (and infrastructure patterns) from an already-running product rather than starting from a blank slate.

How it works

  • Convert: your file is uploaded over HTTPS, converted server-side with dedicated 3D format libraries, and automatically deleted from our servers within 1 hour.
  • View and Compress: these run entirely in your browser using WebGL/WebAssembly. Nothing is uploaded — the file never leaves your device.
  • No account, no email, and no software installation is required for any of the three tools.

Why Convert3D exists

Converting a 3D model shouldn't require installing a full CAD suite. Convert3D is built for hobbyists, 3D printing enthusiasts, engineers, and game developers who just need a fast, free, browser-based way to move between formats.
