Compress uncompressed WAV files into FLAC without losing a single detail and reclaim storage space along the way. The whole process runs in your browser, so your audio never has to be uploaded.
In “Local” mode your file never leaves your device. No uploads, no server – ideal for sensitive recordings.
Pick “Local” for full privacy or “Server” for very large files and every format.
No sign-up, no queue, no watermark. Choose a file, convert, download.

Yes, anytime and without loss. Because FLAC keeps every bit of the original, you can recover a bit-identical WAV file from it.
