ASF is a multimedia container format developed by Microsoft for streaming audio and video. It’s often used with Windows Media Audio (WMA) and Windows Media Video (WMV) codecs. ASF is optimized for playback over networks and supports metadata, subtitles, and DRM.
WMV is a video format developed by Microsoft for online streaming and playback. It uses proprietary codecs and is tightly integrated with Windows systems. WMV files offer good compression and quality and are supported by most media players on Windows.
Convert your .asf files to .wmv right in your browser — no downloads, no installs. Everything happens securely in the cloud.
We never store your files permanently. Only you can access them, and they’re automatically deleted from our servers within 2 hours.
Turn your ASF files into WMV in just a couple of clicks. No registration, no limits — and it’s 100% free.
