Compress audio
Shrink any audio file — a recording, voice note, lecture or podcast — to a much lighter MP3 so it goes by email or fits an upload limit. The file never leaves your device.

Questions
How much smaller?
A WAV recording shrinks 20 times or more. Speech on Voice note usually ends under half a megabyte for two minutes.
Do WhatsApp voice notes (opus) work?
Yes, if your browser can read the file. Chrome and most phones read opus and ogg.
Is my audio uploaded?
No. Everything happens in your browser.
