WMA

WMA is a file format supported by Convertr for online file conversion workflows.

FLAC

FLAC (Free Lossless Audio Codec) is a lossless audio format that compresses music and recordings without removing any audio data. It keeps the original sound quality intact while usually using much less storage than uncompressed WAV. FLAC is popular for music libraries, archiving, hi-fi playback, and converting to other audio formats later.

What happens when WMA becomes FLAC

Source format

WMA is a Microsoft audio format with several codec variants, most commonly lossy.

Target format

FLAC compresses audio without discarding decoded sample data.

What changes

Audio samples are decoded from WMA and encoded according to the FLAC format and selected bitrate or quality.

What is preserved
Duration and audible content are preserved, subject to decoder support and any settings you change.
What may be lost
Tags, embedded artwork, chapters, and codec-specific metadata may not map to FLAC.
Codec and quality implications
Writing FLAC without further lossy compression avoids additional codec loss, but it does not restore detail discarded by the WMA encoding.
Realistic limitations
Protected audio, malformed headers, unsupported codec variants, or files without a decodable audio stream cannot be converted.

Conversion steps

  1. Upload a WMA file no larger than 1 GB.
  2. Confirm that FLAC is selected as the target.
  3. Start the conversion. A healthy compatible worker begins processing immediately.
  4. Download the FLAC file and check the result before deleting your source.

Troubleshooting

The WMA file is rejected or will not open.
Confirm that the file is not empty, password-protected, or corrupt and that its real format matches the extension.
The FLAC file is larger than expected.
Choose a more efficient codec or lower quality setting when available. Lossless and uncompressed targets are often larger by design.
The result has no sound or will not play.
Try a broadly supported target codec and verify that the source contains a decodable audio stream.

Privacy and file retention

Uploads and converted files are processed automatically and irreversibly deleted within 24 hours. You can delete them sooner with the delete control. Convertr does not read, mine, sell, or manually review file contents.
