Convert diagram files to Mermaid

Already have the source file? Skip the screenshot. These converters read the shapes and connections straight out of the file, so the result is exact rather than inferred — and they're free, with no signup and no credits used.

draw.io to Mermaid

Upload a .drawio file and get clean, editable Mermaid.js code. Shapes, labels and connections are read straight from the file, so nothing is guessed.

Accepts .drawio

PlantUML to Mermaid

Upload or paste your PlantUML source and get equivalent Mermaid.js code. No PlantUML server, no Java, no signup.

Accepts .puml, .plantuml, .iuml, .wsd

SVG to Mermaid

Drop an SVG diagram and get editable Mermaid.js code. SVGs exported from draw.io convert exactly, because they carry the original diagram inside them.

Accepts .svg

Visio to Mermaid

Drop a Visio .vsdx file and get editable Mermaid.js code. Shapes, labels and the connections between them are read straight out of the file, so nothing is guessed.

Accepts .vsdx

Going the other way? Export Mermaid to PNG or SVG.
