What Is a Wavefront OBJ File?
OBJ is a plain-text geometry format originally created for the Advanced Visualizer (Wavefront Technologies) in 1990. It stores vertex positions, texture coordinates, normals, and face-vertex indices — one number per line, easy to read and easy to write.
Material info lives in a companion .mtl file that the OBJ references by name. Together they cover most of what designers and game developers used before glTF arrived. OBJ is still the lowest-common-denominator format for 3D interchange.
Who Uses Wavefront OBJ Files?
Used by 3ds Max, Maya, Cinema 4D, Blender, Rhino, MeshLab, ZBrush, and just about every 3D modeling tool ever made. Often the format of last resort when nothing else works.
Common Use Cases
- Preview an OBJ file before importing into your modeling tool
- Verify a download from Sketchfab, TurboSquid, or CGTrader
- Convert OBJ to GLB for web 3D / AR distribution
- Convert OBJ to STL for 3D printing
- Generate a PDF snapshot of the current view
Features
Open Instantly
Drag and drop a .obj file — the viewer auto-loads the sibling .mtl material file from the same path.
3D Navigation
Orbit, pan, and zoom with mouse or touch to explore the model.
Vertex Normals + UVs
Renders vertex normals and texture coordinates when present in the file.
Material Support
Loads the companion .mtl file for per-face Kd / Ks / Ns / d material attributes.
Convert to GLB
Export your OBJ as a GLB file — the universal 3D format for web 3D and AR apps.
Convert to STL
Save as STL for 3D printing, CNC machining, or FEA simulation.
Export as PDF
Generate a snapshot PDF of the current view for documentation.
Universal Compatibility
OBJ is supported by virtually every 3D tool ever made.
No Upload Required
Your OBJ is parsed entirely in your browser. Nothing leaves your computer.
Embed on Any Site
Add the OBJ viewer to your website with a single iframe embed code.
Compatibility & Format Notes
Full support for triangle and quad meshes, vertex normals, texture coordinates, smooth groups, and material references via mtllib. The companion .mtl file must be reachable from the OBJ URL for materials to load — drop the .mtl alongside the .obj.

Your Files Stay on Your Computer
Your Wavefront OBJ files are parsed entirely in your browser. Nothing is uploaded, stored, or shared unless you explicitly click the Share button. Shared files are hosted for 90 days then deleted.
Frequently Asked Questions
▶Do I need to load the .mtl file too?
Only if you want materials. When the OBJ references an .mtl file via the mtllib directive, the viewer fetches it from the same path. If only the .obj is available, the geometry renders in a default gray.
▶What about textures?
Image textures referenced by the .mtl file are loaded automatically as long as they live alongside the .obj. Drop the full folder (or zip and serve from a URL) for the complete look.
▶Why is OBJ still used when glTF exists?
OBJ is older, simpler, and supported by every 3D tool ever made — including legacy software that hasn’t shipped a glTF importer. For complex modern workflows, GLB / glTF is usually the better choice; for “will it open in literally anything,” OBJ is hard to beat.
▶Can I convert OBJ to GLB or STL?
Yes. Click Export in the toolbar and choose GLB (glTF binary), STL (3D printing), or PDF (snapshot).
▶Is this OBJ viewer really free?
Yes, completely free. No signup, no watermarks, no file size limits on the viewer (the optional share-link feature has a 30 MB upload cap). Built by Innerscene as a tool for architects, engineers, and designers.
▶Are my files uploaded to a server?
No. All parsing, rendering, and conversion runs in your browser — nothing is uploaded, stored, or transmitted by default. The Share button is the only feature that uploads a file, and only when you explicitly click it.
▶Can I convert to another format?
Yes. Click Export in the toolbar to save as STL (3D printing), OBJ (Wavefront), GLB (glTF binary), or PDF (snapshot of the current view).
▶Can I embed this viewer on my own site?
Yes. Click Embed in the toolbar to generate a one-line <iframe> snippet you can paste into any HTML page. You can choose whether the embed shows the viewer’s toolbar.
