Move your old WMA files into the lossless FLAC format, which stays smaller than WAV. By default the conversion runs right in your browser.
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.
No. WMA is lossy, and FLAC cannot recover detail that was already discarded. FLAC simply stores the current sound losslessly and compactly.
FLAC is also lossless but compresses the data, so the file is much smaller than a WAV. That makes it well suited to archiving.
By default everything runs in your browser. Very large or unusual WMA files may need the optional server mode to decode them.
It mainly helps if you want your library standardised on a lossless format. It won't improve quality over the WMA source.
