Visio Viewer

What you can do with this tool

• Clear, honest message (not a silent failure) when a real .vsd/.vsdx is opened
• Download button still works — get your original file back
• PDF and SVG exports of a Visio diagram render fully in this site's PDF/image viewers
• Consistent site-wide design even for an unsupported format

Frequently asked questions

Can I actually view a Visio file here right now?

Not yet — there's no viable open-source client-side parser for Visio's format today.

How do I view my Visio diagram in the meantime?

Export it to PDF or SVG from Visio (or open it in free tools like LibreOffice Draw and export from there) — both formats render fully in this site's other viewers.

Is my file uploaded anywhere?

No — even without live parsing, nothing about the file is ever sent to a server.

Will Visio support be added later?

If a viable client-side parser becomes available, yes — this page is ready to be upgraded without changing its URL.

What's the difference between .vsd and .vsdx?

Both are Visio diagram formats — .vsdx is the newer, ZIP-based format; .vsd is the older binary format. Neither has a viable client-side parser today.
