Compress Podcast Audio Online — Reduce Episode File Size

Podcast hosting platforms charge by storage or bandwidth. A 1-hour episode at 320kbps WAV can be 200MB+. Compressing to 64–96kbps MP3 — the industry standard for speech — reduces it to under 30MB with no perceptible difference for listeners.

Recommended bitrate for podcast audio

Podcast guidelines recommend 64kbps mono or 128kbps stereo for speech content. Most listeners on earphones or car speakers can't tell the difference between 64kbps and 320kbps for voice. This tool lets you dial in the exact bitrate before uploading to Buzzsprout, Podbean, Anchor, or any podcast host.
