About Draw.io Viewer
Preview draw.io (diagrams.net) flowcharts and diagrams offline using the official self-hosted viewer. Inspect shapes, stencils, and connectors without sending the file to diagrams.net.
How to Use
Upload or drag in a .drawio, .dio, or .xml file exported from diagrams.net. The viewer renders it with the bundled offline viewer runtime.
Privacy
Diagrams are rendered entirely in your browser using a self-hosted viewer. Nothing is uploaded to a server.
▶Which formats are supported?
diagrams.net native .drawio and .dio files, plus .xml exports. Files that embed external image links may show those images only if they are reachable.
▶Does it need an internet connection?
No. The viewer script and stencils are self-hosted, so diagrams render fully offline without contacting the public diagrams.net service.
