WAV recordings to MP3 — shrink voice memos 10×
A 1-hour 44.1 kHz stereo WAV is ~600 MB. The same content as MP3 is ~55 MB. Portable recorders, call-recording apps and audio interfaces all output WAV by default.
ConvertFlow converts WAV → MP3 entirely in your browser with the LAME encoder. Drag the file in, convert, download — a 1-hour recording takes well under a minute on a modern laptop.
Voice content compresses especially well; the default quality setting keeps speech crisp at a fraction of the size.
