How to convert WAV to FLAC
- Drop your WAV files onto the box, or press Choose files.
- There are no quality settings for this one: the sound is kept exactly as decoded.
- Press Convert. A progress bar shows how far along it is.
- Download your FLAC file, or all of them as a ZIP.
WAV holds uncompressed audio. The files are large, but nothing is thrown away, which is why editors and studios like it. FLAC is lossless compression: about half the size of WAV with no loss of quality, so it suits music collections.
Common questions
Why convert WAV to FLAC?
WAV holds uncompressed audio. The files are large, but nothing is thrown away, which is why editors and studios like it. FLAC is a good choice when you want to edit the sound or keep it without further loss. FLAC is lossless compression: about half the size of WAV with no loss of quality, so it suits music collections.
Will the sound quality drop?
Converting to FLAC adds no further loss. If the original was already compressed (for example MP3 or AAC), that earlier loss stays: FLAC cannot bring back what was removed.
Is my audio uploaded anywhere?
No. The conversion happens inside your browser tab, so your audio never leaves your device. We cannot see it or keep a copy.
Can I convert many files at once?
Yes. Drop several files in and they are converted one after another. When they finish you can download each one, or all of them together as one ZIP.
Why was the first conversion slow to start?
The first time you convert audio or video, your browser downloads the conversion engine (ffmpeg, about 30 MB) from a public CDN. After that it is cached, so the next ones start straight away. Your files are not part of that download.
How big a file can I convert?
Everything runs in your browser's memory, so the limit is your device. We suggest about 500 MB on a computer and 100 MB on a phone. Beyond that, the tab may slow down or run out of memory. A computer is much faster than a phone.
