GEXF to GRAPHML
Converting a .gexf font to .graphml repackages the same glyphs and metrics for a different delivery target. Free, private, and validated — the file never leaves your browser.

Converting a .gexf font to .graphml repackages the same glyphs and metrics for a different delivery target. A .gexf file is Gephi's graph interchange format: XML describing nodes and edges with attributes, and — unlike most graph formats — with first-class support for visual properties and for graphs that change over time.
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 GEXF to GRAPHML?
The practical trigger for this conversion is usually a mismatch: with .gexf, support outside Gephi and its ecosystem is thinner than GraphML's. 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.
GEXF vs GRAPHML at a glance
| Aspect | Graph Exchange XML Format (.gexf) | GraphML graph (.graphml) |
|---|---|---|
| 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 | the graph element's mode attribute is static or dynamic; dynamic graphs attach start and end times to nodes and edges | node and edge attributes are declared once as <key> elements and referenced by <data key="..."> — so the schema is explicit rather than inferred |
| Strongest at | saving and sharing Gephi network visualisations with their styling intact | exchanging network data between yEd, Gephi, Cytoscape and NetworkX |
| Weak spot | support outside Gephi and its ecosystem is thinner than GraphML's | verbose; large graphs produce very large files |
| Metadata | graph meta elements — creator, description, last-modified date — are read; the targets have no equivalent field | node and edge data attributes are preserved into GEXF and JSON; DOT and SVG keep labels only |
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.
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 GRAPHML file. Outputs keep the original filename with the .graphml extension.
GEXF to GRAPHML questions, answered
Will converting GEXF to GRAPHML lose quality?
There is no visual quality to lose — gexf 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 GEXF files here?
Yes — the .gexf 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 GEXF?
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 GEXF file?
In .gexf, graph meta elements — creator, description, last-modified date — are read; the targets have no equivalent field. 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 GEXF?
Yes — the reverse route exists as a separate tool. Bear in mind that round-tripping .gexf → .graphml → .gexf is not a perfect undo when any lossy step is involved; keep your original if fidelity matters.
