Convert HDR to GV
Fast, free, and secure HDR to GV conversion. No registration required.
Whether it's a single file or a hundred, converting hdr to gv with Xonvert is always fast and always free. HDR Image (developed by Greg Ward) since 1985 is radiance hdr format for high dynamic range lighting data. Graphviz Source (by AT&T Labs), introduced in 1991 is alternative extension for graphviz dot graph files. This is one of the most frequently used conversions on Xonvert, with 357 daily conversions on average. The entire conversion pipeline runs in a sandboxed WebAssembly environment for maximum security and performance.
Advantages of GV over HDR
There are strong reasons to convert HDR to GV:
Eco-friendly: Smaller Graphviz Source files mean less bandwidth consumption and lower energy usage during file transfers — a small but meaningful environmental benefit.
Client requirements: Clients, vendors, or regulatory bodies often specify Graphviz Source as the required delivery format for image content.
Cloud storage efficiency: Graphviz Source's efficient encoding makes archival storage practical — important for large collections.
Workflow integration: When your pipeline requires Graphviz Source input, converting from HDR Image is the most reliable bridge between the two environments.
Universal viewer support: Nearly every operating system includes a built-in viewer for Graphviz Source, eliminating the need for third-party applications.

HDR to GV: Quality Comparison
HDR Image retains all original data. Converting to Graphviz Source adds no further quality degradation since it uses lossless compression. Xonvert selects parameters that maximize quality for the target format. For professional use, quality assurance is critical. Xonvert's HDR Image to Graphviz Source pipeline has been tested against reference implementations to ensure output meets diagram industry standards. Real-world quality depends on three factors: source file quality, format capabilities, and encoder settings. Xonvert optimizes the third factor automatically, but starting with the best possible HDR Image source always yields the best Graphviz Source output.
This is a cross-category conversion from Image (HDR Image) to Diagram (Graphviz Source). While these formats serve different purposes, Xonvert extracts the compatible data from your HDR Image source and maps it into the Graphviz Source format. Image files typically contain HDR photography, while Diagram files are used for Graphviz diagrams using the .gv extension to avoid conflicts. The conversion bridges these two domains, allowing you to repurpose your content across different workflows.

HDR to GV FAQ
Is there an API for HDR to GV conversion?▼
Xonvert is a browser-based tool without a server API, since all processing happens client-side. For automated conversion, you can use Xonvert's PRO features or integrate the underlying open-source libraries directly.
Are my files uploaded to a server?▼
No. Zero files are transmitted anywhere. Xonvert processes everything using client-side JavaScript and WebAssembly. Your files stay on your machine.
Can I preview the GV output before downloading?▼
Yes. Xonvert shows a preview of your converted file so you can verify the result before saving it to your device.
Can I convert password-protected HDR files?▼
Encrypted or DRM-protected files cannot be converted. You'll need to remove protection first using the original software.
Can I convert multiple HDR files at once?▼
Yes! Drag multiple files into the converter for batch processing. All files convert simultaneously and can be downloaded as a ZIP archive.
What's the maximum number of files I can convert at once?▼
Free users can convert several files per batch. PRO users enjoy unlimited batch sizes. For very large batches, your device's memory is the only practical limit.
Why choose GV over other formats?▼
Graphviz Source offers identical to .dot — same Graphviz DOT language. It's widely used for Graphviz diagrams using the .gv extension to avoid conflicts, making it an excellent choice for most diagram needs.
