Why convert WMF to PNG?
WMF is a 1990s Windows-only vector format that browsers, web services, and most modern apps do not support. .PNG is lossless, works everywhere, and is the ideal raster format for clipart and line art with flat colors and sharp edges. People also convert WMF files to share diagrams in emails or documents where vector formats are not accepted.
