Compress WMV for Facebook
Compressing WMV for Facebook comes down to three constraints: Facebook's 1 GB cap, its 1920:1080 resolution ceiling, and the need to output MP4 H.264 for reliable inline playback. WMV source files are typically 720p/1080p (Windows Movie Maker) at around 150 MB per minute — right at Facebook's 950 MB target. We calculate a per-clip bitrate budget from your duration, subtract 192 kbps for audio, and allocate the remainder to H.264 video at the highest quality that fits. WMV's VC-1 codec is 2-3× less efficient than H.264; the transcode alone typically cuts file size 60-70% before targeted bitrate reduction. Facebook does not play WMV inline, so this page does a format conversion (WMV → MP4 H.264) plus the size compression in a single pass.

How to compress WMV for Facebook
- 1Drag your .wmv file onto the upload zone above (or browse to it).
- 2Facebook is already selected — we'll target 950 MB to stay safely under the 1 GB cap.
- 3Optionally trim to a highlight clip or switch to H.265 for 30-50% smaller files at the same quality.
- 4Download the compressed MP4 and share it on Facebook. Source file auto-deletes from our servers after 1 hour.
What to know about WMV → Facebook
- WMV's VC-1 codec is 2-3× less efficient than H.264; the transcode alone typically cuts file size 60-70% before targeted bitrate reduction.
- Resolution is kept at up to 1920p when the bitrate budget allows.
- Trim to the highlight before you compress — every 10 seconds you cut gives remaining frames more bitrate to work with.
- Facebook's 950 MB target leaves a 5% safety margin below its 1 GB hard cap, so platform-side rejection is never an issue.
The compression math
A 1-minute WMV at 720p/1080p (Windows Movie Maker) = ~150 MB. Facebook's 950 MB target minus 192 kbps audio = ~132627 kbps video budget. H.264 at that budget kept at up to 1920p when the bitrate budget allows produces a file at the target size that plays inline on Facebook.
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.
