What is VSDX?

Visio Drawing XML (VSDX) is the modern XML-based Visio format introduced in Visio 2013, offering better compatibility and smaller file sizes.

What is DOTM?

DOTM files are built around lossless compression. Designed for corporate templates with macros, automated document generation, they use the application/vnd.ms-word.template.macroenabled.12 MIME type and typically range from varies by content.

When Should You Use VSDX vs DOTM?

VSDX vs DOTM: Key Differences

• •VSDX and DOTM diverge on compression: lossy compression for the source, lossless compression for the target.
• •Moving from VSDX (lossless) to DOTM (lossless) means the output file will be larger — but every bit of the original is preserved.
• •Alpha channel support: DOTM handles transparency.
• •File sizes: VSDX files typically range Smaller than VSD for equivalent diagrams and DOTM files N/A.
• •Primary audience: VSDX is built for modern visio diagrams, process flows scenarios, while DOTM focuses on corporate templates with macros, automated document generation — pick the format that matches your output requirement.
