Free Online OBJ (.obj) File Viewer: Fast Loading, Easy Sharing

The common ways to open OBJ files is to use various 3D modeling software and applications. However, starting in 2024, an easier and better way most users choose to open and view the OBJ file is to use a lightweight OBJ file viewer that works cross-platforms and requires no installation.

To directly convert OBJ file to STL, use a 3D file converter is common choice, however, a better alternative way is to upload the OBJ 3D file to 3D modeling tool then download STL file as format, the best advantage of this way to convert OBJ file to STL is that user can edit / refine the OBJ 3D model during the convert process.

Top 5 advantages of OBJ file are: wide compatibility, rich data storage, human-readable and editable, precise geometry, 3D printing support and separate topology storage, on the other hand, the disadvantages include: large file size, limited material handling and lack of animation support.

There are three ways to reduce the size of an OBJ file: adjust the detail levels, or choose different settings while exporting the 3D model to the OBJ file. The two best ways to compress an OBJ (.obj) file are: 1. directly convert the OBJ file to a GLB/glTF file, or 2. upload the OBJ file to 3D modeling software and download it as a GLB/glTF file format. More users choose method 2 because it allows the user to edit or refine the 3D model during the compression process.
