VDA at a glance
VDA
The Truevision line grew out of EPICenter-era PC graphics boards, and several board names ended up surviving as filename extensions even when the underlying raster structure stayed close to the wider TGA family.
WMF at a glance
WMF
The original WMF specification was published in the Windows 3.1 SDK documentation in 1992. Aldus Corporation independently added a 'placeable' header for device independence, which Microsoft later incorporated in Windows 2000. The format specification was republished in 2006 under the Microsoft Open Specification Promise.

FAQs
Why convert VDA to WMF?
Choose WMF as target when preserving compatibility with older Windows document workflows, embedded legacy graphics, or archive recovery tasks where that classic metafile format is still expected.
What changes when converting VDA to WMF?
Convert to WMF when preserving compatibility with older Windows document workflows, embedded legacy graphics, or archive recovery tasks where that classic metafile format is still expected. It is useful as a bridge for historical Office-era vector assets. For contemporary vector exchange, EMF, SVG, or PDF are usually more practical.
What should I review after converting VDA to WMF?
After conversion, review these destination checks: Open converted output in Microsoft Office and verify behavior on real samples; Compare output against the expected scalable quality profile; 16-bit format with limited precision.
How can I keep quality stable in VDA to WMF conversion?
Run representative samples, keep settings deterministic, and monitor these risks: Not truly device-independent without placeable header; 16-bit format with limited precision; Validate destination compatibility before large-batch conversion.
