Compress WMV for Gmail / Email

WMV attachments trigger two different failures in email: size (Windows Movie Maker exports are usually 100 MB+, blowing past Gmail's 25 MB and Outlook's 20 MB cap) and playability (Mac/iPhone/iPad recipients need VLC or a third-party app to play WMV, killing the inline-preview experience). This page fixes both in one pass: transcode WMV → MP4 H.264 (plays in Gmail's web UI, Outlook's built-in preview, iOS Mail, and macOS Mail without any additional software) and compress to under 25 MB for Gmail/Yahoo or under 20 MB for Outlook (use Custom Size for the tighter target).

What to know about WMVGmail / Email

  • Outlook corporate accounts often cap at 10 MB — use Custom Size 10 MB.
  • Mac/iOS recipients can't play WMV inline without third-party apps — MP4 plays everywhere.
  • Windows Movie Maker exports are famously oversized; expect 70-90% compression.
  • WMV Professional's VC-1 codec → H.264 is a visible quality improvement at the same bitrate.

The compression math

A 3-minute 720p WMV = ~250 MB. Gmail 23 MB target − 128 kbps audio = ~970 kbps video. H.264 720p CRF 28 = ~22 MB. Plays in every email client.

About WMV files

WMV (Windows Media Video) is Microsoft's proprietary video format, commonly produced by Windows Movie Maker and older Windows applications. WMV files play fine on Windows PCs but are incompatible with Mac, iPhone, Android, and every major social media platform. CompressYourVideo.com converts WMV to compressed MP4, making your video playable on any device. WMV is a declining format being replaced by MP4 across the industry, so converting old WMV archives to MP4 also future-proofs your video collection. The compressed MP4 output is typically 30 to 60% smaller than the original WMV while maintaining comparable visual quality.
