How to open a VSDX file without Visio
A .vsdx file is a Microsoft Visio diagram: a flowchart, org chart, floor plan or network drawing. .vsd is the older Visio format. Visio is sold separately from the usual Office apps, so a diagram someone emails you often opens nowhere on your PC. You have a few honest choices, depending on whether you only need to look at it or also need to change it and send it back.
Why it won’t open
Visio is a separate product from Word, Excel and PowerPoint, and Windows doesn’t come with a program for Visio files. If nothing that reads them is installed, double-clicking the file either asks which app to use or opens nothing useful. Renaming the file doesn’t help; the diagram has to be read by something that understands the Visio format.
Free and official options
- Visio for the web, if your work or school has Microsoft 365. Microsoft’s Visio for the web FAQ says you can view basic Visio files without a Visio license: sign in to your Microsoft 365 account, upload the file to OneDrive and open it in the browser, where it is read-only. The same FAQ says Visio in Microsoft 365 is included in commercial and education plans, but Visio for the web isn’t available with the Home or Personal edition of Microsoft 365. The file is uploaded to OneDrive for this.
- Visio Viewer. Microsoft’s Visio Viewer page says it lets you view or print Visio files for free; per the FAQ it cannot create, edit or save drawings. Microsoft’s lifecycle page lists the end of extended support for Visio Viewer 2016 in October 2025.
- LibreOffice Draw. LibreOffice is free and open source. Its 4.0 release notes say it imports all Visio file formats from Visio 1.0 to Visio 2013, so Draw can open .vsd and .vsdx files for viewing and editing. It can’t save back to Visio format; a request for a Visio export filter is still open. If the person who sent the file needs a .vsdx back, this route doesn’t give you one.
| Option | Works offline | Edit | Save as .vsdx |
|---|---|---|---|
| Visio for the web (Microsoft 365 work/school) | No | Depends on plan | Depends on plan |
| Visio Viewer | Yes | No | No |
| LibreOffice Draw | Yes | Yes | No |
| VSDX Diagram Editor | Yes | Yes (supported content) | Yes (3 free, then Pro) |
Steps with VSDX Diagram Editor
- Install VSDX Diagram Editor from Microsoft Store.
- Open the .vsdx or .vsd diagram. Viewing is free, and the file is opened and processed only on your PC; nothing is uploaded.
- Make your changes. Editing supported diagram content doesn’t need a Pro purchase.
- Print it, or save a PDF or PNG copy for free. This is often all you need if you only have to share or attach the diagram.
- Save as .vsdx. The free version includes three .vsdx saves. When you save, the app updates only the parts you changed in the original document structure and keeps unchanged parts, rather than rebuilding the whole file.
- For more saves or for old .vsd files, get Pro: $19.99 one-time in Microsoft Store, no subscription. Pro removes the save-count limit and converts legacy .vsd files to .vsdx.
What it can’t do
- Rotating shapes, manually changing connector routes, deleting pages and moving containers are not supported. If your change needs one of these, use Visio.
- Other supported formats, such as .vsdm, open read-only.
- .vdx files and password-protected files can’t be opened.
- Saving an edited .vsd as .vsdx needs Pro, because that is a conversion from the legacy format.
If you aren’t sure the app fits, open the diagram and try your edit before saving: viewing and editing are free, and the three free saves are only used when you save a .vsdx.
FAQ
Can I open a VSDX file for free?
Yes. VSDX Diagram Editor opens, edits, prints and saves PDF or PNG copies for free, with three free .vsdx saves. Microsoft’s Visio for the web can also show basic Visio files read-only to Microsoft 365 users without a Visio license, and LibreOffice Draw can import Visio files.
What is the difference between .vsd and .vsdx?
.vsd is the older Visio format and .vsdx is the newer one. VSDX Diagram Editor opens both; converting a .vsd to .vsdx needs Pro.
Will the diagram look the same in Visio after I save?
The app saves by updating only the parts you changed in the original document structure and keeping the rest, rather than rebuilding the file. Still open the saved file once to check before sending it on.
Why can’t I open my .vdx or password-protected file?
Those aren’t supported. A .vsdm file opens read-only.
Is Pro a subscription?
No. Pro is a $19.99 one-time purchase in Microsoft Store for unlimited .vsdx saves and .vsd-to-.vsdx conversion.
