Source format: PUML
PUML is a text-based source file used to describe diagrams for PlantUML. It is popular with developers, technical writers, and teams that want diagrams stored as plain text in version control. Typical uses include UML class diagrams, sequence diagrams, activity diagrams, component diagrams, and other documentation visuals. Because the file is plain text, it is easy to edit, diff, and regenerate.
Target format: SVG
SVG is a Scalable Vector Graphics format based on XML. It is widely supported by browsers, design tools, documentation systems, and many editors. SVG is ideal for diagrams because it stays sharp at any zoom level, usually has a small file size, and can be embedded directly into web pages, Markdown, or documentation platforms. It is especially useful when you need a diagram that remains crisp in print and on high-resolution displays.
How to perform the conversion
The most reliable way to convert .puml to .svg is with PlantUML. You can do this locally or use the built-in online converter on 101convert.com for free, without installing any software.
Method 1: using PlantUML locally
- Install PlantUML and make sure Java is available on your system.
- Save your diagram source as
diagram.puml. - Run PlantUML with SVG output enabled. A common command is
java -jar plantuml.jar -tsvg diagram.puml. - PlantUML will create an SVG file with the same base name, such as
diagram.svg.
Method 2: using an editor or IDE plugin
- Open the
.pumlfile in an editor that supports PlantUML, such as VS Code, IntelliJ IDEA, or Eclipse. - Use the PlantUML preview or export function.
- Choose the export option for SVG, often found under File → Export → SVG or a PlantUML-specific export command.
Method 3: using the online converter on 101convert.com
- Open the conversion page on 101convert.com.
- Upload your
.pumlfile. - Select SVG as the output format.
- Start the conversion and download the resulting
.svgfile.
Notes on quality, compatibility, or limitations
SVG is usually the best output format for PlantUML diagrams because it preserves vector quality and is easy to embed in documentation. However, the final appearance depends on the PlantUML version, fonts installed on the system, and any external includes or themes used in the source file. If your diagram uses special fonts or icons, make sure they are available during rendering to avoid layout differences.
Some SVG viewers or documentation platforms may sanitize or restrict embedded scripts and certain advanced SVG features, but PlantUML-generated SVG is generally compatible with modern browsers and editors. If you need a fully self-contained image for older tools, consider also exporting a PNG version for fallback use.
