Convert 3DS to MMD
Fast, free, and secure 3DS to MMD conversion. No registration required.
Professional-grade 3ds to mmd conversion is now available directly in your browser. No software installation needed. 3DS Max Legacy entered the market for legacy 3D asset exchange and simple mesh transfer. Over time, Mermaid Diagram emerged as a strong alternative with renders directly in GitHub, GitLab and many Markdown viewers, which is why this conversion is so popular. Xonvert has processed millions of 3d model conversions, and 3DS Max Legacy to Mermaid Diagram is consistently one of the most reliable format pairs. Works perfectly on Chrome, Firefox, Safari and Edge — no browser extensions or plugins needed.

Quality & Fidelity
Binary format from 3D Studio (DOS predecessor to 3ds Max) JavaScript-based diagram renderer These technical characteristics influence how quality is preserved during conversion. For 3d model-to-diagram conversions, Xonvert applies format-aware algorithms that respect the unique characteristics of both 3DS Max Legacy and Mermaid Diagram. Cross-category conversions require additional adaptation, which Xonvert handles automatically. Document structure and formatting are preserved to the maximum extent supported by both formats.
This is a cross-category conversion from 3D Model (3DS Max Legacy) to Diagram (Mermaid Diagram). While these formats serve different purposes, Xonvert extracts the compatible data from your 3DS Max Legacy source and maps it into the Mermaid Diagram format. 3D Model files typically contain legacy 3D asset exchange and simple mesh transfer, while Diagram files are used for GitHub documentation. The conversion bridges these two domains, allowing you to repurpose your content across different workflows.
The 3DS to MMD conversion applies format-appropriate algorithms to ensure maximum data fidelity. Maximum 65,536 vertices and 65,536 faces per mesh object
