Convert WMA to FLAC
Updated Jul 2026
WMA is the compressed audio format built for Windows Media Player, and FLAC is a lossless format that stores audio without any further loss. To convert WMA to FLAC, open the file in a converter and export it as FLAC. It won't restore quality WMA already discarded, but it does the job on your own computer, with nothing uploaded anywhere.

How to convert WMA to FLAC
- Open Morphjet and drag in the WMA files you want to convert. Add a single track or a whole folder of old rips at once.
- Choose FLAC as the output format.
- Convert. The FLAC files are written next to your originals, and nothing leaves your machine.
WMA vs FLAC: what actually changes
| WMA | FLAC | |
|---|---|---|
| File size | Smaller, roughly 1 MB per minute of audio | Larger, often two to three times the WMA size, since nothing is thrown away |
| Quality | Lossy, some audio detail is discarded permanently at encoding | Lossless, but converting from WMA can't bring back what WMA already discarded |
| Compatibility | Built for Windows Media Player, spotty support on Mac, iPhone, and streaming gear | Widely supported by music apps, media servers, and audiophile hardware, though not natively by iPhone or Apple Music |
| Metadata (tags) | Stores title, artist, and album tags | Stores the same tags, plus handles embedded cover art well |
| Editing and archiving | Awkward to re-encode without further quality loss | Safe to re-encode or archive long term, since no further loss occurs |
When to convert, and when not to
Convert WMA to FLAC when you're moving an old Windows Media Player library into a modern setup, like a NAS, Plex, or hi-fi gear that doesn't recognize WMA at all.
Skip converting if you're only ever going to play the file on Windows itself, since WMA already works fine there and converting won't add back any quality the original encoding lost.
Why not just use an online converter?
Old WMA collections are often personal CD rips, mixtapes, or private recordings, not exactly what you want to hand over to a stranger's server just to change the file extension. An online converter uploads every track, however many gigabytes that adds up to, and keeps a copy somewhere you don't control. Converting on your own computer keeps your library exactly where it already lives.
Questions
Does converting WMA to FLAC improve the sound quality?
No. FLAC preserves whatever detail is in the file it's given, but it can't recover audio that WMA's lossy compression already threw away during the original encoding. It's a format change, not a quality upgrade.
Why convert to FLAC instead of just keeping the WMA files?
FLAC is supported by far more music apps, media servers, and audio hardware than WMA, which is mostly tied to Windows Media Player. Converting makes an old library playable on more devices going forward.
Will my song titles and cover art survive the conversion?
Yes. Morphjet carries over the artist, title, album, and embedded cover art from the WMA file into the new FLAC.
Can I convert a whole music folder at once?
Yes. Point Morphjet at a folder of WMA files instead of a single track, and it converts everything in one pass.
Does converting WMA to FLAC require uploading my music library?
No. Morphjet converts files locally on your computer, so your music never travels over the internet, even for a folder of hundreds of tracks.
