Advanced Batch Processing
Process up to 50 files simultaneously with progress tracking, significantly improving productivity for professionals handling multiple assets. Failed conversions are automatically saved as .error.txt files for easy troubleshooting.
Developer API
Clean, documented REST API with competitive pricing, enabling seamless integration into development workflows and applications. The API maintains the same quality standards as the web interface.
Quality Preservation
Specialized algorithms ensure mesh integrity and prevent quality degradation during conversion. The platform is optimized specifically for 3D formats rather than being a generic file converter.
No Installation Required
All conversions happen directly in your browser with no software downloads needed. This makes ConvertMesh accessible across devices and operating systems while maintaining security.
