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.

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.
