Frequently Asked Questions
Is compressing a WAV file lossless?
It depends on the format you pick. FLAC and 16-bit WAV preserve the audio data (lossless), while MP3 and OGG are lossy formats that reduce file size by removing audio information. The tool always tells you which kind of output you selected.
Why are WAV files so large?
WAV normally stores raw, uncompressed PCM samples: every second of 44.1 kHz stereo 16-bit audio takes about 176 KB. A three-minute song is roughly 30 MB. Lossy or compressed formats can cut that by 80-95%.
Does this WAV compressor upload my file?
No. Decoding and encoding happen entirely inside your browser using Web Audio and local WASM codecs. There is no upload, no queue, and no server-side processing.
