Move between FBX, GLB, OBJ and STL with ready-made converters for the most common format pairs.
Supported 3D File Conversions
Ready-made converters for the most common format pairs. Tap any conversion to open its dedicated converter.
FBX to GLB Converter
Turn heavy FBX production assets into compact, self-contained GLB files for web, AR and real-time use. Animation clips are carried across.
STL to OBJ Converter
Convert a print-ready STL mesh into OBJ so you can edit, retopologize or texture it in Blender, Maya or ZBrush.
OBJ to GLB Converter
Pack a text-based OBJ model into a single compact binary GLB that loads fast in browsers, viewers and engines.
GLB to OBJ Converter
Convert a modern GLB into OBJ, the format almost every 3D application can open, ready for editing and cleanup.
STL to GLB Converter
Turn a 3D print file into a web-ready GLB you can embed in a website, share in a viewer or preview in AR.
GLB to STL Converter
Strip a textured GLB down to the binary STL geometry your slicer expects, ready for 3D printing.
OBJ to STL Converter
Convert an OBJ model into binary STL, the standard format accepted by every 3D printing slicer and print service.

Questions
Vega3D includes ready-made converters for FBX to GLB, STL to OBJ, OBJ to GLB, GLB to OBJ, STL to GLB, GLB to STL and OBJ to STL.
No. Every converter runs entirely in your browser, so there is nothing to download or install.
No. Your file is read and converted locally inside your browser, so it never leaves your device. That also means there is no upload wait.
No account is required. The converters are completely free with no signup, no login and no watermark.
Most converters accept files up to 50MB, and the FBX to GLB converter accepts up to 100MB. For very large files, close other browser tabs to free up memory.
It depends on the target format. GLB keeps materials and textures in a single file, while STL stores geometry only and drops all color. Check the individual converter page for exactly what carries across.
No. The mesh is re-written into the new format, so the shape stays the same. Only format-specific extras like materials may be affected.
Usually a few seconds. Because the work happens on your own device, speed depends on your file size and computer rather than a server queue.
Yes. Because everything runs in the browser, you can convert files on a phone or tablet with no app required.
Yes. Use the Vega3D 3D Viewer to open and inspect your model first, then come back and convert it.
