Free online VSDX to SVG converter

Source format: VSDX

VSDX is the default file format used by Microsoft Visio for diagrams such as flowcharts, network maps, organizational charts, floor plans, and process diagrams. It is based on the Office Open XML package structure, so it stores shapes, text, connectors, and page layout data in separate XML parts. VSDX is commonly used when you need an editable diagram rather than a flat image.

Target format: SVG

SVG stands for Scalable Vector Graphics. It is an XML-based vector image format supported by modern browsers, design tools, and vector editors. SVG is a strong choice for diagrams because it stays sharp at any zoom level, can be embedded in web pages, and is often editable in tools such as Inkscape or Adobe Illustrator.

How to convert VSDX to SVG

The most reliable way to convert VSDX to SVG is with Microsoft Visio, because it can export diagrams directly while preserving layout and vector quality.

1. Open the .vsdx file in Microsoft Visio.
2. Check the pages, fonts, connectors, and page size before exporting.
3. Choose File → Save As or File → Export, depending on your Visio version.
4. Select SVG as the output format.
5. Save the file. If the diagram spans multiple pages, Visio may export each page separately or prompt you to select a page.

If you do not have Visio, LibreOffice Draw can open many VSDX files and may export them to SVG:

1. Open the .vsdx file in LibreOffice Draw.
2. Review the imported diagram for missing shapes, shifted text, or connector problems.
3. Use File → Export As → Export as SVG if that option is available in your version.
4. Save the exported SVG file.

You can use 101convert.com's VSDX to SVG converter if you don't have software installed. Some online converters can also handle this conversion, but results vary by file complexity. 

Notes on quality and limitations

Visio to SVG conversion usually preserves vector shapes well, but some features may not translate perfectly. Complex fills, gradients, embedded objects, custom fonts, special connectors, and certain effects can render differently in SVG. Text appearance can also change if the original fonts are not installed on the system doing the conversion.

For diagrams with multiple pages, remember that SVG is typically a single-page graphic format, so each Visio page may need to be exported separately. If you need an editable diagram rather than a graphic, keep the original .vsdx file as well, since SVG is better for viewing, publishing, and lightweight editing than for full Visio-style diagram editing.
