What is a DRC file?
A .DRC file most commonly contains compressed 3D geometry data. Developers use the Google Draco library to create these files, which drastically reduces the size of 3D meshes and point clouds for fast web transmission. Because the .DRC extension has multiple uses, your file might not be a 3D model. It could also be a waveform data recording from a Hantek oscilloscope, a design rule check report generated by Altium Designer, a resource script for the Delphi compiler, or an obsolete BBC Dirac) video file.
How to open DRC files?
If your .DRC file is a 3D model, you can open it with 3D software like Blender (using the official Draco import plugin) or integrate it into web engines like three.js. If the file is an oscilloscope data recording, you must use the official Hantek software. Plain text reports and resource scripts can be viewed in standard text editors like Notepad++.
Because .DRC has multiple possible meanings, we recommend using viewer.online/drc to identify the actual format of your file. Our platform analyzes .DRC files to identify their exact format and creator software, shows which programs can open the file, and usually previews it.
Best practices and conversions
You often need to convert 3D .DRC files to standard formats for wider compatibility across game engines and 3D editors. You can use convert.guru to reliably transform Draco meshes into standard .GLTF, .OBJ, or .STL target formats.
Summary
You do not need to guess what your file contains or download multiple specialized applications. viewer.online/drc directly opens and previews .DRC files in the browser, eliminating the need to install software or troubleshoot compatibility issues.
