Frequently asked questions
How do I open a .bpmn file without installing anything?
Drag the file onto this page. It renders instantly in the browser using bpmn-js, the same engine behind Camunda Modeler and bpmn.io. There is nothing to install and no account to create.
Is my diagram uploaded anywhere?
No. The file is read and rendered entirely on your device. Nothing is uploaded, logged, or stored. You can even use the viewer offline once the page has loaded.
Can I export the diagram as an image?
Yes. Once a diagram is loaded you can download it as SVG (crisp at any size, great for documents) or PNG (2× resolution, great for slides and chat). Both exports include a white background and clean margins.
Which tools produce compatible files?
Any tool that exports BPMN 2.0 interchange XML: Camunda Modeler, bpmn.io, Signavio, Bizagi, ARIS, Visio with BPMN export, Lucidchart, and Swimdraft itself.
Can I edit the diagram here?
The viewer is read-only. If you need to move shapes, rename elements, or reconnect flows, the Swimdraft studio includes a full BPMN editor with live spec validation on every change.
Need to create diagrams, not just view them?
Swimdraft turns meeting notes, transcripts, and spreadsheets into editable, spec-validated BPMN 2.0 diagrams. First 5 diagrams free.
