About the WAV format
WAV (Waveform Audio) stores audio uncompressed as raw PCM samples, exactly as it was recorded or decoded. It is the standard for recording, editing and mastering because nothing is lost, and it plays everywhere. The price is size: a minute of CD-quality stereo takes about 10 MB.
About the FLAC format
FLAC (Free Lossless Audio Codec) compresses audio without losing anything: decode it and you get the original samples back, at roughly half the size of WAV. It supports tags and album art and is the format of choice for music collections and hi-res audio.
Frequently asked questions
Why convert WAV to FLAC?
FLAC is lossless and about half the size of WAV, with full tag support, which makes it ideal for music collections. WAV files are huge, about 10 MB per minute, which makes them impractical to send or stream.
Does converting WAV to FLAC lose quality?
No. FLAC is a lossless format, so every sample of the decoded WAV audio is stored exactly. The file is usually larger than the original.
Can I convert several WAV files at once?
Yes. Add up to 5 files of up to 200 MB each, convert them in one go and download the results one by one or as a ZIP.
Are my files uploaded?
No. The conversion runs in your browser with ffmpeg compiled to WebAssembly. Your WAV files never leave your device.
