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

What is ICS?

iCalendar (ICS) is the standard format for calendar event data, enabling event sharing across different calendar applications.

When Should You Use VSDX vs ICS?

Use VSDX When...

Reach for VSDX when your priority is modern visio diagrams, process flows — its efficient compression makes sharing fast and storage minimal.

Use ICS When...

Reach for ICS when your priority is calendar sharing, event scheduling, meeting exports — its uncompromising quality ensures every detail is preserved.

VSDX vs ICS: Key Differences

  • •The core technical difference: VSDX relies on lossy compression whereas ICS uses lossless compression.
  • •Converting from VSDX to ICS changes compression type: lossless source becomes larger but with full quality preservation.
  • •Transparency: N/A
  • •VSDX files are typically Smaller than VSD for equivalent diagrams while ICS files range Very small per event
  • •VSDX is optimized for modern visio diagrams, process flows while ICS is designed for calendar sharing, event scheduling, meeting exports — choose based on your specific workflow needs
