When Should You Use WMF vs RAW?

WMF vs RAW: Key Differences

• •WMF uses lossless compression while RAW uses lossless compression — both take the same approach to file size management.
• •Since both WMF and RAW use lossless compression, the quality characteristics are comparable — differences in file size come down to how efficiently each format implements compression.
• •Alpha channel support: RAW lacks transparency support.
• •File sizes: WMF files typically range 10KB to 5MB and RAW files 20-50MB per photo depending on camera.
• •WMF is optimized for office documents, legacy vector graphics while RAW is designed for professional photography, post-processing, editing — choose based on your specific workflow needs

Troubleshooting WMF to RAW Conversion

• !RAW shows visible compression artifacts → lower the compression level or switch to a lossless variant
• !The converted RAW image looks washed out → the source WMF likely uses a wider color space than RAW supports
• !RAW file is much larger than expected → check if the conversion preserved an unnecessarily high resolution
• !Text in the converted RAW looks fuzzy → text-heavy images benefit from higher quality settings or a different output format
