Email-friendly by default
The default preset targets ~64 kbps — small enough to attach to nearly any email, clean enough for voice.
Works with video too
Drop an MP4, MOV or WEBM and we'll strip the video automatically so you get just the audio, compressed.
Privacy
Files are never listened to, never shared, and permanently deleted after one hour.
