Questions about M4A to WAV
- Does converting M4A to WAV improve the sound?
- No. M4A is lossy, so the detail it dropped when it was encoded is gone for good. Lossless WAV stores the sound you have now without losing anything further, but the file gets much bigger.
- Which bitrate should I choose?
- For speech, podcasts and audiobooks 96–128 kbps is enough. For music, 192–256 kbps is the usual sweet spot; below that, cymbals and reverb start to smear.
- Is there a file size limit?
- No limit that we impose. The only ceiling is your device's memory, so a very large photo or a long recording may take a few seconds.
- Are my files uploaded anywhere?
- No. The conversion runs inside this browser tab, so the file never leaves your device — go offline once the page has loaded and keep converting.
