What is WMF?

Windows Metafile (WMF) is a vector and raster graphics format used by Microsoft Office for clip art and simple illustrations.

What is HEIC?

HEIC (High Efficiency Image Container) is a modern image format developed by the HEVC industry group. It uses advanced compression to achieve much smaller file sizes than JPEG.

When Should You Use WMF vs HEIC?

Use WMF When...

Reach for WMF when your priority is office documents, legacy vector graphics — its uncompromising quality ensures every detail is preserved.

Use HEIC When...

Reach for HEIC when your priority is ios photography, mobile devices — its efficient compression makes sharing fast and storage minimal.

WMF vs HEIC: Key Differences

  • •WMF uses lossless compression while HEIC uses lossy compression — this is the fundamental technical difference between the two formats.
  • •The switch from lossless compression to lossy compression means you gain significant space savings while accepting minor quality trade-offs.
  • •Alpha channel support: HEIC handles transparency, so semi-transparent pixels from the source will be lost.
  • •Storage footprint: 10KB to 5MB for WMF vs 50% smaller than equivalent JPEG for HEIC.
  • •WMF is optimized for office documents, legacy vector graphics while HEIC is designed for ios photography, mobile devices — choose based on your specific workflow needs

Advantages of WMF

  • ✓At its core, WMF relies on lossless encoding — a design choice that makes it perfect for Office documents, legacy vector graphics.
  • ✓You won't run into compatibility issues with WMF — it's a universal standard across platforms.
  • ✓File size management with WMF: larger files guaranteed to match the original exactly.
  • ✓Every major application in the Office documents, legacy vector graphics space supports WMF natively.

Advantages of HEIC

  • ✓HEIC applies lossy compression specifically calibrated for iOS photography, mobile devices.
  • ✓HEIC enjoys broad native support across operating systems, browsers, and creative tools alike.
  • ✓HEIC delivers impressive compression ratios, shrinking files dramatically while keeping visual quality high.
  • ✓You will find HEIC support built into virtually every tool that handles iOS photography, mobile devices — no plugins or converters needed.

Troubleshooting WMF to HEIC Conversion

  • !Converting WMF to HEIC gives blurry output → increase the quality setting before conversion
  • !Colors look different in HEIC than WMF → check color profile mismatch (sRGB vs Adobe RGB)
  • !File size changed more than expected → HEIC uses different compression, file size differences of 2-5x are normal
  • !Transparent areas in WMF turned white in HEIC → HEIC may not support transparency

FAQs

Is converting WMF to HEIC free?

Yes, GoConvertFile offers free conversion of WMF to HEIC for files up to 100MB. No registration required.

How long does it take to convert WMF to HEIC?

Most WMF to HEIC conversions complete within seconds for standard-sized files. Larger files may take longer depending on the conversion complexity.

What is HEIC best used for?

HEIC is ideal for ios photography, mobile devices. HEIF/HEIC - Apple High Efficiency Image Container

Does converting WMF to HEIC lose quality?

Yes, converting WMF to HEIC uses lossy compression, which reduces file size by discarding some visual data. Set quality to 85-95% for a good balance of quality and file size.

What file size should I expect after converting WMF to HEIC?

HEIC files are typically 50-80% smaller than WMF files because HEIC uses efficient lossy compression. The exact reduction depends on quality settings.

Will transparency be preserved when converting WMF to HEIC?

No, HEIC does not support transparency. Any transparent areas in your WMF will be filled with a solid color (usually white) during conversion. Use PNG or WebP if transparency is needed.
