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.

A more private way to convert Visio files
Plenty of sites convert Visio files. Very few promise never to keep them — PrivConvert does, and backs it up with how the service is built.
Every conversion runs in its own locked-down process with no network access, so files can never leak or interfere with one another.
Your files are handled entirely by automated code. No staff, partner or AI model ever reads, stores or trains on your data.
Files are processed in volatile memory (RAM) and purged the instant your download is ready — nothing is ever written to disk, cached or backed up.
Every upload and download is protected with TLS 1.3, so your document cannot be intercepted on the way to the server or back to you.
