Convert the Legacy VSD File to VSDX Format

Since Visio for the web only supports the modern VSDX format, converting your older VSD file is the most effective way to open and edit it online.

Visio for the web in Microsoft 365 is designed to work exclusively with the newer VSDX format. To bridge this compatibility gap, you must use a third-party conversion tool or a desktop version of Visio to upgrade the file format.

1
Choose a conversion tool

Find a reputable online file converter that supports VSD to VSDX conversion, or open the file in a desktop version of Microsoft Visio if you have it installed.

2
Convert and save the file

Upload your VSD file to the converter and select VSDX as the output format. Run the conversion and download the resulting file to your local drive.

3
Upload to Visio for the web

Log in to Microsoft 365, open Visio for the web, and upload your newly converted VSDX file to seamlessly view and edit your organization chart.

Frequently Asked Questions

Why can't I open my VSD file in Visio for the web?

Visio for the web is optimized for the newer VSDX format introduced in Visio 2013. It does not possess the legacy components required to natively support opening or editing the older binary VSD files.

What is the primary difference between VSD and VSDX?

VSD is the older, proprietary binary file format used by Visio 2010 and earlier versions. VSDX is the modern, XML-based open format used by newer versions of Visio, which offers significantly better file compression, stability, and security.

Is there a way to open VSD files without a desktop version of Visio?

Yes, you can use reputable third-party online conversion tools to safely convert your VSD file into a VSDX file. Once converted, the VSDX file can be seamlessly uploaded and opened in Visio for the web.
