FLAC is lossless compression for audio: it makes a file smaller the way ZIP does, and decoding it gives back exactly the samples that went in. A WAV of recorded music typically shrinks to somewhere between half and two thirds of its size, with no change to how it sounds. This converter encodes FLAC in the browser with a WebAssembly build of the reference libFLAC encoder, because no browser ships a FLAC encoder of its own.
No. FLAC is lossless: decoding the file reproduces the input samples exactly, bit for bit.
No. The MP3 already threw information away when it was made, and FLAC can only preserve what is left. You get a larger file that sounds identical to the MP3. Convert to FLAC from WAV, a CD rip, or another lossless source.
It depends on the audio. Dense, loud music compresses least, often to around 60 to 70 percent of the WAV. Speech, quiet passages and silence compress much further.
Same sound, smaller files, and FLAC can carry tags such as artist and title that WAV handles poorly. Most music players, phones and editors read it.

Add audio files
WAV is the usual source. MP3, M4A, AAC, OGG and Opus files, and the soundtrack of MP4, MOV and WebM videos, are accepted too.

Convert
The encoder loads on first use, then each file is compressed on your device.

Download
One file downloads as .flac; several arrive in a ZIP.
- ·Keep the result lossless all the way: edit from the FLAC or WAV, and only export to MP3 or AAC at the very end.
- ·The first conversion takes a moment longer because the encoder has to download; later files start immediately.
