About WMV Compression
WMV (Windows Media Video) is Microsoft's proprietary format, common in corporate presentations, training videos, and older Windows Movie Maker projects.
CocoConvert re-encodes WMV files using efficient H.264 within the WMV container. For most use cases, converting to MP4 is recommended — but if WMV compatibility is required, our compressor delivers substantial size reduction.
WMV files encoded with the WMV3 codec (common in XP-era content) compress especially well with modern techniques, often achieving 60-80% reduction.
Batch processing handles multiple WMV files simultaneously on Pro plans.
