Uncompressed sound
A WAV file stores every sample of the sound as it is: CD-quality stereo (16-bit, 44.1 kHz) takes about 10 MB per minute. That is ideal for recording and editing, but too heavy to email, upload or keep by the hundred.

Compress WAV
WAV files are uncompressed and heavy. Turn one into an MP3 or OGG that is often 80 to 90% lighter, at the quality you pick.

Why WAV files are so big
Compressing a WAV means changing its format
There is no meaningful way to make a WAV small while keeping it a WAV. Compressing it means encoding it as MP3 or OGG: at 128 kbps an MP3 is about 1 MB per minute, at 192 kbps about 1.4 MB, which most listeners can't tell apart from the original for speech and most music.
Choose the quality, see the result
Pick the bitrate and the format, and the page shows the size before and after for each file. When a setting would not make a file lighter, the original is kept. Everything runs in your browser: your recordings are never uploaded.

Practical guides
Tips & guides
Which bitrate?
Voice notes, podcasts and interviews sound fine at 96–128 kbps. Music keeps its detail at 192 kbps and above.
Keep the original WAV if you will edit the sound again: every compression loses a little, so compress once, at the end.
TipRecordings stay private
The audio is encoded in your browser with FFmpeg: nothing is uploaded to a server.
Unreleased songs, interviews and voice memos never leave your device.
