How to do it, step by step
- Select the WAV files.
- Click Convert all (FLAC does not use a bitrate).
- Download the FLACs and check the size.
When this is useful
Archive high-quality recordings
Keep masters and original recordings taking up less disk.
Lossless music collection
FLAC is accepted by most quality audio players and streamers.
Tips for a good result
- The final size depends on the audio: very dense music compresses less than voice recordings.
- To go back to WAV later, use the FLAC to WAV page: the decoded audio is the same.
What this tool does not do
- Bitrate does not apply: FLAC is always lossless.
- The generated file has the characteristics the browser can decode from the original WAV; WAVs of unusual formats may fail.
- The new file carries the “WebFaz.com” credit in the metadata (comment and artist).
Frequently asked questions
- Does FLAC really not lose quality?
- It does not: when decoded back, the audio is equal to what was encoded.
- How much does the file shrink?
- It varies with the audio, but it usually ends up much smaller than the WAV.
