Convert WAV to FLAC online
Compress WAV recordings into FLAC and save space without losing a single sample of 16-bit audio. Ideal for archiving sessions and music libraries, with nothing uploaded.
Your files stay on your device: they are processed in this browser tab’s memory and never uploaded.
Same sound, less space
FLAC typically reduces music to about half to two thirds of its WAV size while keeping the audio intact, which makes it the standard for archives and collections.
Good for long-term storage
FLAC is an open format with wide support, so your files will stay readable for years to come.
FAQ
Is FLAC really lossless?
Yes. Decoding a FLAC gives back the same samples that were encoded.
How much space will I save?
It depends on the material. Quiet speech and simple music compress the most, and dense, loud music the least.
Is my WAV uploaded?
No. The encoding runs on your device.
What can you do with an audio converter?
Editors turn phone recordings into WAV files that every timeline accepts; podcasters export a small MP3 from a large master; musicians archive takes as lossless FLAC; and anyone stuck with a file a device refuses to play can switch it to a format that works everywhere.
