Do I need Visio or a Microsoft 365 account?

No. Drop the file and it is read for you. Microsoft's own web viewer asks for a Microsoft 365 sign-in first.

Is my file uploaded anywhere?

It is sent to our server, parsed in memory, and dropped when the response is sent. No account, no history, nothing written to disk.

Which Visio versions does it read?

The .vsdx format, which is Visio 2013 and later. Lucidchart exports to the same format, so those work too. The older binary .vsd is not supported.

My diagram has several pages — which one do I get?

Every page in the file is listed and you pick the one to draw. Pages are never merged, because merging them would invent adjacency the author never drew.

A screenshot works too — PNG, JPEG or WebP, read by a model rather than parsed. On the paid plans.

Your file is read once to draw the diagram and is never stored. Converting turns on anonymous usage analytics — we never send your file, its contents or your brand URL. What we measure

Now put it on your brand

Paste any URL. We read its palette and type and redraw the diagram in them — about a second, no account.

Line

Clean Ruled and square Soft Edges bow slightly — subtle, and costs nothing Hand-drawn Every line drawn twice, corners miss, focal box shaded

Depth

Flat Bars and wedges as areas Relief Extruded, for bar, histogram and pie

A bar in relief still measures correctly — the top face sits on the bar's end. A pie does not: squashing the circle makes the near slices read larger than the far ones at the same share.
