About converting Graphviz DOT graph to GraphML graph

Converting a .dot font to .graphml repackages the same glyphs and metrics for a different delivery target. 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.

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. For this route the practical draw is extensible attribute model that does not break older readers and broad support across graph-analysis and drawing tools — balanced against verbose; large graphs produce very large files, which is worth knowing before you commit a large batch.

Why convert DOT to GRAPHML?

The practical trigger for this conversion is usually a mismatch: with .dot, layout control is indirect; fighting the engine for a specific arrangement is frustrating. Switching to .graphml buys you extensible attribute model that does not break older readers, which is why it is the better fit for exchanging network data between yEd, Gephi, Cytoscape and NetworkX. Because the conversion runs locally, trying it costs nothing but a few seconds of compute on your own machine.

01

Add your DOT file

Drop one or more .dot 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.

02

Pick GRAPHML as the output

Select .graphml in the output menu next to each file. The menu only offers targets this engine can genuinely produce, so if GRAPHML is selectable, the route is real and validated.

03

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.

04

Verify and download

Each result is signature-checked before the download unlocks, so a failed encode can never masquerade as a valid GRAPHML file. Outputs keep the original filename with the .graphml extension.

DOT to GRAPHML questions, answered

Will converting DOT to GRAPHML lose quality?

There is no visual quality to lose — dot is text-oriented and graphml 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 DOT files here?

Yes — the .dot 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 GRAPHML file work?

yEd, Gephi, Cytoscape, NetworkX, igraph and JGraphT read GraphML. Novus Convert parses topology and labels locally, with document types and external entities blocked, and converts to GEXF, DOT, JSON and SVG — the SVG being a direct rendering rather than a re-export.

Will the GRAPHML file be bigger or smaller than my DOT?

It depends on the content: node and edge attributes are declared once as <key> elements and referenced by <data key="..."> — so the schema is explicit rather than inferred. Convert one representative file first and compare before batch-processing a large set.

What happens to the metadata in my DOT file?

In .dot, 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. 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 GRAPHML back to DOT?

Yes — the reverse route exists as a separate tool. Bear in mind that round-tripping .dot → .graphml → .dot is not a perfect undo when any lossy step is involved; keep your original if fidelity matters.
