fh9 to svg conversion represents export of old Adobe FreeHand drawings to SVG format, something users that own old .fh9 files often need, in order to work with their old vectors in modern software.
Freehand has been discontinued years ago, yet many tools still accept the old formats, most notably Adobe Illustrator. You can also still find installation packages for various versions of FreeHand on Internet, so this is also a viable option.
