When to Convert

Common scenarios where this conversion is useful

Archiving WMA music library in a future-proof format

WMA is a proprietary Microsoft format with uncertain long-term support. Convert your WMA collection to FLAC to preserve audio in a stable, open-standard lossless format that will remain accessible indefinitely.

Linux music player compatibility

Linux audio players like Rhythmbox, Clementine, Amarok, and Strawberry don't support WMA natively. Convert WMA files to FLAC for seamless playback on Linux without additional codec packages.

Audiophile NAS and home audio servers

Network audio servers (Naim, Bluesound, Roon, Logitech Media Server) prefer FLAC for lossless streaming. Convert WMA files to FLAC for integration with high-fidelity home audio systems.

Preventing generation loss for future re-encoding

If you need to convert WMA to multiple other formats in the future, converting to FLAC first creates an intermediate with no further lossy encoding loss.

Frequently Asked Questions

No. WMA is a lossy codec, and any audio quality loss already present in the WMA file carries over to the FLAC. FLAC stores the decoded PCM losslessly, but quality cannot exceed what the WMA already has.

Three reasons: (1) FLAC prevents further quality loss on future re-encodes, (2) FLAC is an open standard with better long-term compatibility than proprietary WMA, and (3) FLAC works natively on Linux and audiophile systems.

Yes, mostly. FFmpeg transfers metadata like title, artist, album, and track number from WMA to FLAC's Vorbis comment format. Cover art and some Windows-specific metadata fields may not transfer completely.

Not natively in the Music app. FLAC playback on iPhone requires VLC for iOS or a similar third-party player. For Apple device library use, AAC or M4A are better output choices.

Yes. Foobar2000 has excellent native FLAC support. The converted FLAC will play perfectly and foobar2000 can also run ReplayGain scanning and tag editing on FLAC files.

FLAC files are typically 3–5x larger than WMA files. A 5 MB WMA file may become 15–25 MB as FLAC, depending on the audio content complexity and original WMA bitrate.

No. WMA files with PlayReady DRM protection cannot be converted without authorization. Only DRM-free WMA files can be processed by this converter.
