draw.io Beautifier — turn drawio diagrams into clean documentation visuals

It imports your draw.io / mxGraph XML, parses the structure into the same internal representation Mermaid and PlantUML use, then re-renders the diagram with a theme-matched palette, cleaner spacing, and consistent edge routing. The original draw.io file is not modified — beautification is an export pass.

Both the default compressed `.drawio` export and plain uncompressed XML work — you can upload a `.drawio` or `.xml` file directly, or paste the XML into the editor. Multi-page files are on the roadmap but not yet handled — export or copy a single page for now.

Flowcharts, sequence diagrams, class diagrams, entity-relationship diagrams, mindmaps, and git branching diagrams convert natively — shapes, branches, actors, message order, class members and relationship types, table columns with keys and cardinality, mindmap hierarchy, and commit/branch/tag structure all carry over. Class and ER diagrams need recognizable UML or ER relationship arrows; one drawn with plain arrows imports as a flowchart, and the "Enhance parsing with AI" toggle usually reads it. Swimlane, org chart, BPMN, and network diagrams keep their full structure and grouping but arrive as flowcharts. Gantt charts and bar/pie charts are drawn by hand in draw.io with the numbers living in the shapes themselves, so those need AI enhancement — and the recovered values are approximate.

No — import handles one diagram at a time. draw.io's canvas is infinite, so it's easy to end up with two or three unrelated diagrams side by side on one page; a file like that is rejected with a message rather than converted, because the result would silently mix or drop parts of your diagrams. Copy the diagram you want onto its own page (or file) and re-export. Multi-page files import the first page. A single diagram with a title, legend, or floating notes around it imports normally.

Yes. draw.io import runs through a built-in converter — no AI needed — and is free with no signup required. The optional "Enhance parsing with AI" toggle — useful for messier or nonstandard diagrams — is included with Pro and Premium plans, or can be paid per use from a credit pack without a subscription. Check the pricing page for current details.

draw.io is a manual canvas — every clean-up requires moving nodes, picking colors, and rerouting edges by hand. The beautifier reads the structure and emits a polished render automatically: theme palette, spacing, edge routing, and label hierarchy applied in one pass. Useful as a finishing step before pasting into a deck or doc.

Yes. Once imported, the diagram lives in the editor as Mermaid or PlantUML source — you can adjust labels, add nodes, or change branches as if you had drawn it that way originally. Re-export at any time as SVG (for docs) or HD PNG (for slides).
