OBJ vs TXT: Format Comparison
Key differences between the two formats
| Feature | OBJ | TXT |
|---|---|---|
| Primary data | 3D mesh geometry, vertices, faces, materials | Readable text with extracted metadata and geometry info |
| File structure | Binary/text with vertices, normals, UV coordinates | Plain text lines for documentation and analysis |
| Use case | 3D modeling, rendering, game assets | Asset cataloging, technical documentation, metadata extraction |
| Editability | Requires 3D software (Blender, Maya, 3ds Max) | Editable in any text editor |
| File size | Compact for complex meshes | Larger due to human-readable formatting |
| Compatibility | 3D software and game engines | Universal text readers, databases, spreadsheets |
When to Convert
Common scenarios where this conversion is useful
3D asset metadata extraction
Convert OBJ files to TXT when you need to catalog 3D assets by extracting readable information about vertex counts, material lists, object names, and geometry properties for documentation or inventory systems.
Technical documentation for CAD workflows
Generate text reports from OBJ exports to share mesh specifications with team members who need technical details but don't have 3D modeling software installed.
Quality assurance and asset auditing
Extract OBJ mesh data into text format for automated quality checks, asset validation scripts, or compliance reporting that requires readable geometry information.
Material and texture inventory
Convert OBJ files to TXT to extract material definitions and texture references for asset management systems that track textures and shaders across multiple 3D projects.
Who Uses This Conversion
Tailored guidance for different workflows
For 3D Artists and Modelers
- Extract readable mesh information from OBJ exports for portfolio documentation or client deliverables
- Generate text reports of model specifications without opening heavy 3D modeling software
For Game Developers and Technical Artists
- Extract asset metadata from OBJ models for game asset pipelines and optimization workflows
- Generate readable asset reports for QA teams to validate mesh complexity and material assignments
For Asset Managers and Production Teams
- Catalog 3D assets by extracting metadata without requiring expensive 3D software licenses for every team member
- Generate human-readable asset inventories from batches of OBJ files for project tracking and documentation

Frequently Asked Questions
No. The conversion happens entirely in your browser. Your OBJ file never leaves your device, ensuring complete privacy for your 3D assets.
Yes. ChangeThisFile is completely free with no limits on conversions or file sizes.
The TXT output contains readable metadata such as vertex coordinates, face definitions, normal vectors, texture coordinates, material names, object groups, and other geometric properties found in the OBJ file.
No. The TXT conversion extracts readable information for analysis and documentation. It cannot recreate a working 3D model file. Keep your original OBJ file for 3D editing and rendering.
Most 3D modeling software can export OBJ files, including Blender, Maya, 3ds Max, Cinema 4D, SketchUp, and many CAD applications. OBJ is one of the most widely supported 3D formats.
Since conversion happens in your browser, the limit depends on your device's available memory. Most typical 3D model files convert without issues.
Yes, the text extraction reads the actual geometric data from the OBJ file format. However, the TXT output is formatted for human readability and documentation, not for mathematical precision.
Yes, if your OBJ file references materials or texture files (common in exports from 3D software), that information will be included in the readable text output.
OBJ files don't contain animation data - they're static mesh formats. The TXT conversion extracts the geometric mesh information, but any animation would be stored in separate files or different formats.
No. This converter works entirely in your web browser. You just need an OBJ file from any source - no 3D modeling software required.
While OBJ files are text-based, they use specific formatting that can be hard to read. This converter extracts and formats the data in a more readable way for documentation and analysis purposes.
Yes, the text output can be imported into Excel, Google Sheets, or databases for analysis. For more structured data analysis, consider converting to CSV format instead.
