| Audio codec | WMA (Windows Media Audio) | FLAC lossless codec |
| Platform | Windows-native, limited elsewhere | Universal — all major platforms and players |
| File size | Moderate (video included) | Moderate — lossless audio compression |
| Audio quality | WMA quality (lossy, decent) | Bit-perfect reproduction of decoded audio |
| Use case | Windows video playback | Lossless audio libraries, archiving, DAWs |
When to Convert
Common scenarios where this conversion is useful
Archive audio from Windows Media Video presentations
Corporate presentations, recorded meetings, and training videos in WMV format often contain valuable audio content. Extract to FLAC for a lossless audio archive playable on any platform without Windows Media Player.
Extract audio from WMV home videos for lossless preservation
Home video recordings from early digital camcorders and Windows-era video software were often saved as WMV. Extract the audio as FLAC to preserve memorable moments in a lossless, universally accessible format.
Convert WMV music video audio for HiFi listening
If you have music content in WMV format, extracting to FLAC allows playback on HiFi players and audiophile systems that support FLAC but may not support Windows Media formats.
Prepare WMV audio for professional editing on non-Windows systems
WMV is a Windows-centric format. Extracting audio as FLAC creates a universally compatible audio source file for editing in Logic Pro on Mac or Audacity on Linux without Windows Media codec dependency.
Build a cross-platform audio archive from WMV collection
WMV files may not be playable on all platforms. Convert audio from your WMV collection to FLAC to create a cross-platform audio archive that works on Windows, macOS, Linux, and mobile devices.

Frequently Asked Questions
WMV files almost always contain WMA (Windows Media Audio) for the audio stream. FFmpeg decodes WMA when extracting to FLAC.
FLAC is lossless — no further quality is lost during conversion. However, WMV audio is WMA, which is a lossy codec. The FLAC stores the decoded WMA audio without additional degradation, but cannot recover quality lost by WMA encoding.
Yes. FLAC is supported on Android, iOS/macOS (since iOS 11 and macOS 10.13), Linux, and by virtually all modern desktop media players. It is much more universally supported than WMA.
FLAC avoids adding another round of lossy compression on top of the WMA audio. If you plan to edit or further process the audio before final export, starting with FLAC preserves maximum quality through the editing chain.
FLAC removes the video stream and compresses audio losslessly. For a typical WMV file, the FLAC output is significantly smaller since the video track is removed and only the audio is retained and compressed.
Yes. Both Plex and Kodi support FLAC natively. Converting WMV audio to FLAC allows it to be organized in your Plex or Kodi music library with full metadata support.
Yes. ChangeThisFile is completely free. No signup, no limits, and no fees.
FLAC uses Vorbis comment tags supporting artist, album, title, track number, year, genre, and embedded cover art. Tags from the WMV file may partially transfer.
Typically under 30 seconds. FFmpeg processes only the audio stream and discards the video, making conversion faster than full transcoding.
Yes. All uploads use HTTPS encryption and files are deleted from our servers immediately after conversion. We never retain or access your content.
