Archive Your WMA Files as Lossless FLAC Without Losing More Quality
WMA is a Microsoft proprietary lossy format. Converting to FLAC losslessly stores whatever audio the WMA contains, stopping the quality loss at the original encoding with no further degradation. The result works in every audiophile player, media server, and DAW on any platform.

Stop Quality Loss at the Original WMA Encoding
WMA is a lossy format that discards audio data during encoding. Converting WMA to another lossy format like MP3 or AAC applies a second round of compression on top of the first, degrading quality further. Converting to FLAC instead losslessly stores the PCM decoded from the WMA file, freezing the quality ceiling at the original WMA encoding. Any future re-conversion from the FLAC introduces at most one new lossy pass, not a compounding second one.

Play WMA-Sourced Audio in Roon, Plex, and Every Audiophile Player
Roon, Plex, Jellyfin, Navidrome, and most audiophile-grade media servers have strong native FLAC support but inconsistent or no WMA decoding. Converting a WMA library to FLAC makes every track readable by any serious music player on any platform, including Linux, NAS devices, and network streamers that never shipped with Microsoft codec support.

Rescue a Zune or Windows Media Center Archive
Microsoft Zune purchases, Windows Media Player CD rips, and Windows Media Center recordings were all stored in WMA. As Windows hardware ages out, those libraries need a migration path. Converting to FLAC gives each track a universally supported lossless container that plays in any player, imports into any DAW, and survives indefinitely without the proprietary codec dependency that WMA carries.

Convert to FLAC
Click "Convert". FFmpeg decodes the WMA stream to PCM and encodes it losslessly as FLAC. No additional quality is lost beyond what was discarded in the original WMA encoding.

Deep Dive
WMA vs FLAC: Proprietary Lossy Codec vs Open Lossless Archive
WMA encodes audio with perceptual compression and stores it in a Microsoft-proprietary container. FLAC applies fully reversible compression with no information loss, in an open format supported by every serious audio player on every platform.
Our converter uses FFmpeg to decode WMA to PCM and encode losslessly as FLAC, preserving the audio at the quality level of the original WMA source.
Why Convert WMA to FLAC
No Further Quality Loss
FLAC stores the decoded WMA audio losslessly. Quality is frozen at the original WMA encoding with no additional compression pass.
Works Everywhere
FLAC is natively supported by Roon, Plex, VLC, foobar2000, Kodi, Android, Linux, and virtually every audiophile player and NAS device.
Future-Proof Archive
FLAC is an open, royalty-free format. Re-encoding from FLAC to any delivery format later produces a fresh single-pass encode, not a compounding multi-generational loss.
Fast Conversion
Most WMA files convert to FLAC in under 30 seconds on dedicated FFmpeg servers.

Frequently Asked Questions
Does converting WMA to FLAC improve audio quality?
No. FLAC is lossless compression, which means it stores the PCM data decoded from the WMA file exactly as-is. Quality lost during the original WMA encoding cannot be recovered. The benefit is that no additional quality is lost during the conversion, and any future re-encoding from the FLAC to a delivery format like MP3 or AAC will be a fresh single-pass encode rather than a compounding multi-generational loss.
Why convert WMA to FLAC instead of MP3 or AAC?
Converting WMA to MP3 or AAC applies a second round of lossy compression on top of the already-lossy WMA encoding, degrading the audio twice. Converting to FLAC instead stores the decoded WMA audio losslessly, preserving it at the original WMA quality with no further degradation. If you later need an MP3 or AAC, you can encode it from the FLAC as a clean first-generation lossy encode.
Will FLAC files be larger than the original WMA files?
Yes. WMA is a lossy compressed format; FLAC is lossless. A 4-minute WMA track at 128 kbps is roughly 4-5 MB. The same audio as FLAC will typically be 20-35 MB, depending on the original recording. FLAC is still 40-60% smaller than uncompressed WAV, but it is considerably larger than any lossy format.
Does FLAC play on Android?
Yes. Android has supported FLAC natively since Android 3.1 and all versions since then decode FLAC without any additional app. Popular Android music players including VLC, Poweramp, and Neutron also support FLAC with full metadata and gapless playback.
Can I use the FLAC file in Roon or Plex?
Yes. Roon and Plex both handle FLAC as a first-class format with full metadata support, gapless playback, and library analysis. FLAC is the recommended format for both platforms. WMA support in Roon and Plex is version-dependent and can be incomplete, making FLAC a more reliable choice for these servers.
Is there a file size limit?
The upload limit is 100 MB per file. Most WMA audio files are well within this limit.
