FITS at a glance
FITS
Convert to FITS when preserving scientific image data, observation metadata, or instrument-derived captures for astronomy and research workflows.
It is the right target when measurement context matters as much as the picture itself.
WMF at a glance
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.

FAQs
Why convert FITS 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 changes when converting FITS to WMF?
This conversion changes how the format behaves in downstream tools and delivery environments.
Size profile changes from medium in FITS to small in WMF. Quality profile changes from depends in FITS to scalable in WMF. Editability profile changes from moderate in FITS to high in WMF. Compatibility profile changes from broad in FITS to moderate in WMF. Archival profile changes from moderate in FITS to good in WMF. Workflow profile changes from delivery in FITS to design in WMF.
Moving to WMF adds vector scaling.
What should I review after converting FITS to WMF?
Check the exported file for 16-bit format with limited precision.; Not truly device-independent without placeable header.; Security vulnerabilities have been discovered historically..
