Conversion Quality Deep Dive
HDR Image's known limitation — large files, limited display support for full HDR range — is resolved when converting to Mermaid Diagram, which offers renders directly in GitHub, GitLab and many Markdown viewers. The HDR Image source uses lossless encoding. The Mermaid Diagram output uses lossless encoding. Since both share the same compression philosophy, quality transfer is highly efficient. Xonvert's conversion engine analyzes your HDR Image source and selects the optimal encoding strategy for Mermaid Diagram output. Dynamic range far exceeds standard 8-bit images Native rendering in GitHub Markdown (```mermaid code blocks) These implementation details are handled automatically by the converter.
This is a cross-category conversion from Image (HDR Image) to Diagram (Mermaid Diagram). While these formats serve different purposes, Xonvert extracts the compatible data from your HDR Image source and maps it into the Mermaid Diagram format. Image files typically contain HDR photography, while Diagram files are used for GitHub documentation. The conversion bridges these two domains, allowing you to repurpose your content across different workflows.
The HDR to MMD conversion applies format-appropriate algorithms to ensure maximum data fidelity. Used for environment maps and Image-Based Lighting (IBL)

Yes. Free users can batch-convert multiple files. Simply drag all your HDR files into the converter at once. PRO users get higher batch limits and priority processing.
What's the difference between HDR and MMD?▼
HDR Image is radiance hdr format for high dynamic range lighting data. Mermaid Diagram is mermaid.js diagram source for modern web documentation. Key difference: HDR Image excels at captures extreme brightness ranges for realistic lighting, while Mermaid Diagram offers renders directly in GitHub, GitLab and many Markdown viewers.
How does the HDR to MMD conversion work technically?▼
Xonvert uses WebAssembly-compiled libraries to decode your HDR file in-browser, process the image data, and re-encode it as MMD. All processing happens on your device's CPU.
What happens to my files after conversion?▼
Nothing — your files exist only in your browser's memory during conversion. Once you close the page, all data is cleared. No files are stored anywhere.
What is HDR format?▼
HDR Image is Radiance HDR format for high dynamic range lighting data. It is primarily used for HDR photography, 3D lighting environments and tone mapping. Stores luminance data in RGBE (RGB + exponent) encoding
Will the conversion strip my EXIF or metadata?▼
Xonvert preserves metadata (EXIF, XMP, ID3, etc.) when the target MMD format supports it. You can optionally strip metadata in the settings for smaller, cleaner output files.
