WAV to MP3 for Podcast — Free Online Converter

Most podcast recording software saves audio as WAV files — lossless, high-quality, but large. Before distributing your podcast, you need to convert WAV to MP3 to meet platform requirements and reduce file size for faster downloads.

Podcast platform requirements for MP3:

• Spotify: Recommends 128 kbps mono or 192 kbps stereo MP3
• Apple Podcasts: Accepts 128–320 kbps MP3, recommends 128 kbps mono for voice
• Buzzsprout: Recommends 128 kbps mono MP3 for voice content
• Anchor / Spotify for Podcasters: Accepts MP3 up to 200 MB per episode
• RSS feeds: MP3 is the universal standard for podcast RSS enclosures

Converting your podcast WAV recording to MP3 takes just a few steps:

1. Drop your WAV file onto the converter above — your recording stays on your device.
2. Select 128 kbps for voice-only podcasts, or 192 kbps for music-heavy content.
3. Click Convert — processing happens locally in your browser.
4. Download your MP3 and upload directly to your podcast host.

For voice-only podcasts, 128 kbps is the industry standard — it sounds excellent for speech while keeping file sizes small for faster downloads.

128 kbps MP3 is the recommended bitrate for podcast audio because:

• Voice quality: Speech sounds excellent at 128 kbps — the human voice does not require high bitrates to sound clear.
• File size: A 30-minute podcast episode at 128 kbps is approximately 28 MB — fast to download on any connection.
• Bandwidth costs: Smaller files mean lower hosting costs and faster delivery to listeners.
• Platform compatibility: 128 kbps MP3 is accepted by every podcast platform and RSS reader.
• Mobile listening: Smaller files use less mobile data for listeners on the go.

A typical podcast production workflow using WavinTools:

1. Record your episode in WAV format using Audacity, GarageBand, or your DAW.
2. Edit your recording — cut mistakes, add music, adjust levels.
3. Normalize your audio to -16 LUFS using our Volume Normalizer (the podcast standard).
4. Remove silence using our Silence Remover to tighten up the episode.
5. Convert to MP3 at 128 kbps using this converter.
6. Upload to your podcast host (Buzzsprout, Anchor, Podbean, etc.).
