Drop one or more .graphml files onto the converter above, or browse for them. They load into browser memory only — nothing is uploaded, so there is no size-based pricing and no server queue.
GRAPHML to DOT
Converting a .graphml font to .dot repackages the same glyphs and metrics for a different delivery target. Free, private, and validated — the file never leaves your browser.

Converting a .graphml font to .dot repackages the same glyphs and metrics for a different delivery target. A .graphml file describes a graph in XML: a <graph> element containing <node> and <edge> elements, with arbitrary typed attributes attached to either through <key> declarations and <data> values. It expresses topology first and leaves layout to whoever draws it.
A .dot file is a Graphviz DOT description: a small declarative language for graphs, in which nodes and edges are written as statements — a -> b — with optional attributes controlling labels, shapes and colours. It describes the graph's structure and leaves the layout to the renderer. For this route the practical draw is automatic layout — the hard part of drawing a graph is done for you and compact and readable, so diagrams can be generated and diffed as text — balanced against layout control is indirect; fighting the engine for a specific arrangement is frustrating, which is worth knowing before you commit a large batch.
Why convert GRAPHML to DOT?
The practical trigger for this conversion is usually a mismatch: with .graphml, verbose; large graphs produce very large files. Switching to .dot buys you automatic layout — the hard part of drawing a graph is done for you, which is why it is the better fit for rendering dependency, call and state-machine diagrams from generated data. Because the conversion runs locally, trying it costs nothing but a few seconds of compute on your own machine.
GRAPHML vs DOT at a glance
| Aspect | GraphML graph (.graphml) | Graphviz DOT graph (.dot) |
|---|---|---|
| Format type | Text-based — characters and structure, so there is no visual quality loss | Text-based — characters and structure, so there is no visual quality loss |
| How it stores data | node and edge attributes are declared once as <key> elements and referenced by <data key="..."> — so the schema is explicit rather than inferred | digraph declares a directed graph using -> edges; graph declares an undirected one using -- |
| Strongest at | exchanging network data between yEd, Gephi, Cytoscape and NetworkX | rendering dependency, call and state-machine diagrams from generated data |
| Weak spot | verbose; large graphs produce very large files | layout control is indirect; fighting the engine for a specific arrangement is frustrating |
| Metadata | node and edge data attributes are preserved into GEXF and JSON; DOT and SVG keep labels only | nodes, edges, direction and label attributes are preserved. Layout and styling attributes have no equivalent in the graph interchange targets and are not carried across |
Pick DOT as the output
Select .dot in the output menu next to each file. The menu only offers targets this engine can genuinely produce, so if DOT is selectable, the route is real and validated.
Convert on your device
Press Convert. The font tables are parsed and rewritten locally with fonteditor-core; glyph outlines, hinting, and kerning survive the trip.
Verify and download
Each result is signature-checked before the download unlocks, so a failed encode can never masquerade as a valid DOT file. Outputs keep the original filename with the .dot extension.
GRAPHML to DOT questions, answered
Will converting GRAPHML to DOT lose quality?
There is no visual quality to lose — graphml is text-oriented and dot is text-oriented, so the question is structural fidelity. Text, ordering, and basic structure are preserved; complex layout, embedded objects, and styling beyond the target's model are simplified.
Is it private to convert GRAPHML files here?
Yes — the .graphml file is processed inside your browser tab and never uploaded. The font tables are parsed and rewritten locally with fonteditor-core; glyph outlines, hinting, and kerning survive the trip. Close the tab and the file is gone from memory.
Where will the DOT file work?
Read by Graphviz and by many libraries and services that embed it, including documentation generators and profiling tools. Novus Convert parses the graph locally and converts to GraphML, GEXF, JSON and a rendered SVG.
Will the DOT file be bigger or smaller than my GRAPHML?
It depends on the content: digraph declares a directed graph using -> edges; graph declares an undirected one using --. Convert one representative file first and compare before batch-processing a large set.
What happens to the metadata in my GRAPHML file?
In .graphml, node and edge data attributes are preserved into GEXF and JSON; DOT and SVG keep labels only. Re-encoding through the browser pipeline does not carry embedded metadata into the output, which doubles as a privacy scrub — check the exported file if you specifically need tags preserved.
Can I convert DOT back to GRAPHML?
Yes — the reverse route exists as a separate tool. Bear in mind that round-tripping .graphml → .dot → .graphml is not a perfect undo when any lossy step is involved; keep your original if fidelity matters.
