Add your GRAPHML file
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 GEXF
Converting a .graphml font to .gexf 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 .gexf 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 .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. For this route the practical draw is native visual and temporal modelling, which most graph formats omit entirely and clean, readable XML that maps closely to how Gephi thinks about graphs — balanced against support outside Gephi and its ecosystem is thinner than GraphML's, which is worth knowing before you commit a large batch.
Why convert GRAPHML to GEXF?
The practical trigger for this conversion is usually a mismatch: with .graphml, verbose; large graphs produce very large files. Switching to .gexf buys you native visual and temporal modelling, which most graph formats omit entirely, which is why it is the better fit for saving and sharing Gephi network visualisations with their styling intact. Because the conversion runs locally, trying it costs nothing but a few seconds of compute on your own machine.
GRAPHML vs GEXF at a glance
| Aspect | GraphML graph (.graphml) | Graph Exchange XML Format (.gexf) |
|---|---|---|
| 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 | the graph element's mode attribute is static or dynamic; dynamic graphs attach start and end times to nodes and edges |
| Strongest at | exchanging network data between yEd, Gephi, Cytoscape and NetworkX | saving and sharing Gephi network visualisations with their styling intact |
| Weak spot | verbose; large graphs produce very large files | support outside Gephi and its ecosystem is thinner than GraphML's |
| Metadata | node and edge data attributes are preserved into GEXF and JSON; DOT and SVG keep labels only | graph meta elements — creator, description, last-modified date — are read; the targets have no equivalent field |
Pick GEXF as the output
Select .gexf in the output menu next to each file. The menu only offers targets this engine can genuinely produce, so if GEXF 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 GEXF file. Outputs keep the original filename with the .gexf extension.
GRAPHML to GEXF questions, answered
Will converting GRAPHML to GEXF lose quality?
There is no visual quality to lose — graphml is text-oriented and gexf 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 GEXF file work?
Gephi, NetworkX, igraph, sigma.js and Cytoscape (via plugins) read GEXF. Novus Convert normalises topology and labels locally without network access or external entity expansion, and converts to GraphML, DOT, JSON and SVG. Visual and temporal attributes are not carried into the targets, none of which can represent them.
Will the GEXF file be bigger or smaller than my GRAPHML?
It depends on the content: the graph element's mode attribute is static or dynamic; dynamic graphs attach start and end times to nodes and edges. 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 GEXF back to GRAPHML?
Yes — the reverse route exists as a separate tool. Bear in mind that round-tripping .graphml → .gexf → .graphml is not a perfect undo when any lossy step is involved; keep your original if fidelity matters.
