Common questions
How do I convert WAV to FLAC?
Open the FLAC converter, drop your WAV file onto it and press Convert. Everything runs in your browser — the file is not uploaded. Desktop browsers handle files up to about 200MB; mobile browsers about 40MB.
Does converting WAV to FLAC lose quality?
Not on the encoding side. FLAC does not discard data when written, so nothing further is lost — though anything the WAV source already discarded stays gone.
Is it free to convert WAV to FLAC?
Yes, with no account, no watermark and no daily limit. The processing happens on your device rather than on a server, so there are no per-conversion costs to pass on.
Are my files uploaded when converting WAV to FLAC?
No. FFmpeg runs as WebAssembly inside your browser tab. The file is read from your disk, processed in memory and written back out — it never reaches a server.
