In your browser
- Open the Visio Viewer.
- Drop your .vsdx, .vsd or .vsdm file on the page. Every page of the drawing appears, free, so you can check it first.
- Click PNG to download a picture of each page. The first time it asks for a license: $19 once, then PNG and PDF downloads work in that browser for every drawing.
The free way: a screenshot
For a single small diagram, open it in the viewer and take a screenshot (Windows: Win+Shift+S, Mac: Cmd+Shift+4, Chromebook: Ctrl+Shift+Show windows). That costs nothing, and for one page it's all you need. The PNG download saves you doing it page by page: each page comes as its own picture, up to 1600 pixels on the long side, in one zip (the first 20 pages). For a huge network diagram or floor plan that has to stay sharp when zoomed, use the PDF instead.
With Visio or LibreOffice
In Visio, File, Export, Change File Type, PNG saves the current page. In LibreOffice Draw (free), File, Export, PNG does the same, page by page. LibreOffice on its own often draws Visio 2013 and later files with black shapes; the Visio Viewer fixes those theme colours first.
PNG or PDF?
- PNG for slides, documents, chat and tickets: one picture per page that pastes anywhere.
- PDF for printing or zooming into a large drawing: the lines stay sharp at any zoom and the text can be searched. See VSD to PDF.
