How to open and convert Visio (.vsdx) files without Microsoft Visio
Someone sent you a Visio diagram — a process map, an org chart or a network drawing — and you don't have Visio. You don't need it. You can open the file and turn it into a PDF or image for free, right in your browser.
Open a .vsdx file in four steps
- Open the Visio viewer.
- Drop your .vsdx file onto the page. It stays on your device.
- Move between pages and zoom in to read the labels.
- Need to share it? Use the Visio converter to save it as PDF, PNG, JPG or SVG.
Which format to choose
- PDF — best for email, printing and keeping every page together.
- PNG — sharp image for slides, Word documents and chat.
- JPG — smaller image when file size matters more than crisp lines.
- SVG — keeps shapes as lines you can still edit in a design tool.
- Text — pulls out every label, handy for reviewing or translating the wording.
Want to change the diagram?

FAQ
Can I open a Visio file without Microsoft Visio?
Yes. The Toolsii Visio viewer opens .vsdx files in your browser for free, with no Visio licence and no software to install.
Is my diagram uploaded anywhere?
No. The file is opened inside your browser tab, so company diagrams and process maps stay on your device.
Does it work with old .vsd files?
Not directly. The older .vsd format is a different, closed format. Open it once in Visio or a free online Visio alternative, save it as .vsdx, then use Toolsii.
Which format should I convert to?
PDF for printing and email, PNG for slides and documents, SVG if you want to keep editing the shapes in a design tool.
Will the converted diagram look exactly the same?
Shapes, lines and text come across well. Unusual fonts, custom stencils or special effects may look slightly simpler than in Visio.
