Frequently Asked Questions
What is an online 3D file viewer?
An online 3D file viewer opens and renders 3D models directly in your web browser without installing any software. Trify3D viewers run entirely client-side using WebGL, so your files never leave your device. They support STL, OBJ, GLB, FBX, PLY, 3MF, Blend, DAE, IGES and USDZ formats.
Are these 3D viewers free?
Yes. All Trify3D viewers are completely free with no sign-up, no watermarks, and no file size limits beyond your device's memory. View as many 3D files as you need.
Are my files private?
Yes. Every viewer processes your file entirely in your browser. Nothing is uploaded to a server, stored, or accessed by anyone else. This makes them safe for confidential CAD and design work.
Which 3D file formats are supported?
Trify3D supports 10 formats: STL and 3MF (3D printing), OBJ and DAE (general 3D), GLB and USDZ (web/AR), FBX (animation), PLY (point clouds), Blend (Blender), and IGES (NURBS CAD). Pick the viewer that matches your file extension.
Can I view 3D files on mobile?
Yes. All viewers work in mobile browsers (iOS Safari, Chrome for Android) with touch controls for pinch-to-zoom and drag-to-rotate. Large files may take longer to render on mobile devices.
Do I need to install software?
No. These are browser-based viewers that require no download or installation. They work on Windows, macOS, Linux, iOS, and Android in any modern browser with WebGL support.
What is the difference between STL and GLB?
STL stores only geometry as triangles (ideal for 3D printing, no color). GLB stores geometry plus PBR materials, textures, and animations in a single file (ideal for web 3D). Use the STL Viewer for printing models and the GLB Viewer for textured web models.
Which viewer should I use?
Match the viewer to your file extension: .stl files use STL Viewer, .obj use OBJ Viewer, .glb use GLB Viewer, and so on. If you need to convert between formats instead of just viewing, open the Convert Studio.
Need to Convert Between Formats?
Open the Convert Studio to convert your 3D files between any of the 48+ supported formats.
