Convert PUML to PLANTUML
Fast, free, and secure PUML to PLANTUML conversion. No registration required.
No app to install, no account to create — just open this page, drop your puml file, and get plantuml output in seconds. What makes this conversion useful: PlantUML Diagram gives you UML diagrams from text — version-controllable and diffable, but PlantUML Source unlocks PlantUML diagrams using self-documenting extension — something PlantUML Diagram struggles with (requires PlantUML renderer, learning curve for syntax). This is one of the most frequently used conversions on Xonvert, with 588 daily conversions on average. The entire conversion pipeline runs in a sandboxed WebAssembly environment for maximum security and performance.

PUML to PLANTUML: Quality Comparison
PlantUML Diagram's known limitation — requires PlantUML renderer, learning curve for syntax — is resolved when converting to PlantUML Source, which offers same PlantUML syntax as .puml with explicit extension. The PlantUML Diagram source uses lossless encoding. The PlantUML Source output uses lossless encoding. Since both share the same compression philosophy, quality transfer is highly efficient. Xonvert's conversion engine analyzes your PlantUML Diagram source and selects the optimal encoding strategy for PlantUML Source output. Can be embedded in AsciiDoc, Markdown and Confluence Processed by the same PlantUML renderer These implementation details are handled automatically by the converter.
Converting diagram source files from PlantUML Diagram to PlantUML Source translates the graph definition, node relationships, and styling information. This allows you to edit and render diagrams in different visualization tools and documentation systems.

PUML to PLANTUML FAQ
What is PLANTUML format?▼
PlantUML Source is PlantUML diagram source with full extension name. It is primarily used for PlantUML diagrams using self-documenting extension. Identical to .puml — same PlantUML markup language
Is Xonvert open source?▼
Xonvert uses open-source conversion libraries (FFmpeg, libvips, etc.) compiled to WebAssembly. The conversion engine is transparent and trustworthy.
Can I use Xonvert offline?▼
Yes! Once the converter page has loaded, it works without an internet connection. All conversion logic runs locally in your browser.
Does PUML to PLANTUML conversion work on slow internet?▼
Yes — and even with no internet at all. Once the page loads, conversion is entirely offline. Speed depends on your device's CPU, not your internet connection.
How is Xonvert different from other online converters?▼
Most online converters upload your files to their servers. Xonvert processes everything locally in your browser — your files never leave your device. It's faster, more private, and works offline.
Is there a file size limit?▼
There is no strict file size limit. However, very large files (over 500MB) may be limited by your device's available memory.
What are the advantages of PLANTUML over PUML?▼
PlantUML Source offers same PlantUML syntax as .puml with explicit extension, while PlantUML Diagram is known for UML diagrams from text — version-controllable and diffable. The best choice depends on your specific needs — compatibility, quality, or file size.
