Convert MMD to GLTF
Fast, free, and secure MMD to GLTF conversion. No registration required.
No app to install, no account to create — just open this page, drop your mmd file, and get gltf output in seconds. What makes this conversion useful: Mermaid Diagram gives you renders directly in GitHub, GitLab and many Markdown viewers, but glTF 3D Model unlocks web 3D (Three.js, Babylon.js), AR/VR and runtime 3D delivery — something Mermaid Diagram struggles with (limited styling options compared to dedicated diagramming tools). This is one of the most frequently used conversions on Xonvert, with 441 daily conversions on average. Bookmark this page for quick access whenever you need this conversion again in the future.
Advantages of GLTF over MMD

MMD to GLTF: Quality Comparison
Mermaid Diagram encodes data using mathematical algorithms that preserve every data point. glTF 3D Model prioritizes exact data preservation. The conversion maps between these approaches intelligently. Mermaid Diagram's known limitation — limited styling options compared to dedicated diagramming tools — is resolved when converting to glTF 3D Model, which offers compact, web-optimized with PBR materials — the "JPEG of 3D". The Mermaid Diagram source uses lossless encoding. The glTF 3D Model output uses lossless encoding. Since both share the same compression philosophy, quality transfer is highly efficient.
This is a cross-category conversion from Diagram (Mermaid Diagram) to 3D Model (glTF 3D Model). While these formats serve different purposes, Xonvert extracts the compatible data from your Mermaid Diagram source and maps it into the glTF 3D Model format. Diagram files typically contain GitHub documentation, while 3D Model files are used for web 3D (Three.js. The conversion bridges these two domains, allowing you to repurpose your content across different workflows.
The MMD to GLTF conversion applies format-appropriate algorithms to ensure maximum data fidelity. Supports flowcharts, sequence, Gantt, class, ER and pie diagrams
