MP3 (.mp3) · Max 20 MB
Edit your podcast in WAV to avoid generation loss. Export to a lossy format only as the final step before uploading to your host.
For spoken word, 128kbps mono is plenty. Music-heavy podcasts benefit from 192kbps stereo. AudioUtils lets you choose the right balance of size and quality.
Record in the highest quality your setup allows. Convert to your distribution format once, at the end. Every extra conversion degrades lossy audio slightly.
Frequently Asked Questions
Does converting MP3 to WAV improve quality?
No. MP3 is lossy — once compressed, the discarded data can't be recovered. Converting to WAV gives you an uncompressed container, but the audio quality stays identical to the source MP3. It's purely a compatibility move for editors that require WAV or for workflows where you don't want to keep re-decoding an MP3.
What sample rate and bit depth does the WAV use?
The output is 16-bit PCM at the same sample rate as the source MP3 (typically 44.1 kHz for music and 48 kHz for voice recordings). That matches CD-quality — exactly what DAWs and audio editors expect. If your MP3 was encoded at 22.05 kHz or 32 kHz, the WAV preserves that rate rather than upsampling.
How long does MP3 to WAV conversion take?
Usually 1–3 seconds for a typical 5-minute song. Everything runs locally in your browser using FFmpeg compiled to WebAssembly. No upload, no server processing, no queue. Larger files (hour-long podcasts, audiobooks) take proportionally longer but are still measured in seconds on a modern laptop.
Will the WAV file be larger than the MP3?
Yes, about 10× larger. A 128 kbps MP3 at 5 MB becomes ~50 MB as 16-bit 44.1 kHz WAV. A 320 kbps MP3 is already closer to WAV in data rate, so the size jump is more like 4×. If file size matters, keep the MP3 for storage and only convert to WAV when you're about to edit.
Will Pro Tools / Logic / Ableton accept the converted WAV?
Yes. The output is standard Microsoft WAV (RIFF) with 16-bit PCM data — the universal flavor that every DAW, NLE, and audio editor on Windows, macOS, and Linux reads without complaint. No DAW-specific metadata stripping needed.
Can I use this WAV on CD burning software?
Yes — output is CD-ready (44.1 kHz sample rate matches Red Book). Most CD burning tools (iTunes, Nero, Windows Media Player, Burn on macOS) import the WAV directly. If your MP3 was at a different sample rate, you may want to resample to 44.1 kHz in an audio editor before burning.
Is this converter free?
Yes. Free users get 5 conversions per month. The output is limited to the first 10 seconds as a preview, with a 20MB input file size limit. Upgrade to Pro for unlimited, full-length conversions.
