Share a Visio diagram with anyone
Visio files only open in Visio, so sharing a flowchart, network map or floor plan usually means exporting to PDF first. This converter turns both the legacy .vsd and modern .vsdx into a clean PDF that opens on any device — while your file stays private, processed entirely in memory inside a network-free sandbox and never stored.
About Converting Visio to PDF
Microsoft Visio (.vsd for the legacy binary format, .vsdx for the newer OpenXML one) is the standard tool for diagrams — flowcharts, network maps, floor plans, org charts and engineering schematics. The trouble is that opening a Visio file requires Visio itself, which most recipients do not have, so sharing a diagram usually means first turning it into a PDF everyone can view.
PrivConvert renders your Visio drawing through the LibreOffice engine and exports a PDF that preserves the pages, shapes, connectors and text. The conversion runs entirely in server memory inside an isolated, network-free sandbox, and your file is discarded the instant the PDF is ready — nothing is stored, logged or reused.
Common use cases
- Sending a flowchart or network diagram to someone who does not own Visio
- Attaching a diagram to a report, proposal or email as a universally viewable PDF
- Archiving Visio diagrams in a long-lived, portable format
- Publishing a process map or org chart on the web or an intranet
Tips for best results
- Both the legacy .vsd and the modern .vsdx (and .vdx) formats are accepted.
- Visio is a closed Microsoft format, so rendering relies on an open-source interpreter (libvisio). Very complex or heavily-styled diagrams can differ slightly from how Visio itself would draw them — check the PDF before sharing anything critical.
- Multi-page Visio files export to a multi-page PDF, one diagram per page.
- Fonts your diagram relies on are substituted with close matches if they are not available on the server.
