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.

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.

When Should You Use DOTM vs VSDX?

DOTM vs VSDX: Key Differences

• •The core technical difference: DOTM relies on lossless compression whereas VSDX uses lossy compression.
• •Moving from DOTM (lossy) to VSDX (lossy) means the output file will be significantly smaller — but at the cost of some visual fidelity.
• •Alpha channel support: VSDX lacks transparency support, so semi-transparent pixels from the source will be lost.
• •VSDX files tend to be differently sized than DOTM
• •Use case fit: DOTM targets corporate templates with macros, automated document generation and VSDX targets modern visio diagrams, process flows — your choice depends on which workflow stage you are serving.

Advantages of DOTM

• ✓DOTM applies lossless compression specifically calibrated for Corporate templates with macros, automated document generation.
• ✓DOTM enjoys broad native support across operating systems, browsers, and creative tools alike.
• ✓DOTM guarantees every bit of the original data survives — no approximations, no shortcuts.
• ✓You will find DOTM support built into virtually every tool that handles Corporate templates with macros, automated document generation — no plugins or converters needed.

Advantages of VSDX

• ✓At its core, VSDX relies on lossy encoding — a design choice that makes it perfect for Modern Visio diagrams, process flows.
• ✓You won't run into compatibility issues with VSDX — it's a universal standard across platforms.
• ✓File size management with VSDX: aggressive compression with minimal visible quality loss.
• ✓Every major application in the Modern Visio diagrams, process flows space supports VSDX natively.
