💡 Good to know
- The wav output is uncompressed, so the result is larger than the source — that is normal for the format.
- The kept sample rate makes the file drop-in ready for any editing workflow.
- The first run loads the audio engine once; after that every conversion is instant.
- If you mistype m4a ro wav or m4a tp wav and end up here, you are in the right place.

❓ Frequently asked questions
❓ How do I convert m4a to wav with this extension?
💡 Open the side panel, drop the source, and the audio is decoded to an output you can download right away.

❓ Does my audio get uploaded?
💡 No. The source is processed entirely in your browser and never sent anywhere.

❓ What quality do I get?
💡 The output is 16-bit pcm and keeps the original sample rate and channels. For Apple Lossless sources you get a clean lossless step (16-bit final).

❓ Can I convert several files at once?
💡 Yes. Drop several m4a clips and the extension turns each one into a wav output, then hands them back together.

❓ What if the source has no audio?
💡 If there is no sound to extract, the extension tells you instead of saving an empty file.

❓ How long does it take?
💡 Short clips are almost instant; longer ones take a little more, with a progress bar the whole time.
