Batch conversion, ZIP download and quality control
- Convert many files at once — drop or pick several M4A files and they are converted one after another.
- When you convert two or more files, the results are bundled into a single ZIP so you download everything in one click.
- Adjust quality and size: lower the quality or resize to make the WAV files smaller. The setting applies to every file in the batch.

Frequently asked questions
Is my M4A file uploaded when I convert it to WAV?＋
No. The conversion runs entirely in your browser using your device, so your file is never sent to any server.
Will the quality drop when I convert M4A to WAV?＋
Converting to WAV (lossless) keeps the current pixels, but cannot recover detail that M4A already lost.
Can I convert several M4A files to WAV at once?＋
Yes. Add multiple files and they are converted one by one in your browser. A single file downloads directly; two or more are packed into one ZIP. If one file fails, the others still convert.
Is it free? Do I need to sign up?＋
Yes, it is completely free — no sign-up, no install and no watermark.
Is there a file size limit?＋
You can convert files up to 100 MB. Everything is processed on your device, so very large files depend on your available memory.
Can I convert the other way, from WAV back to M4A?＋
That direction is not available right now. M4A can still be converted to several other formats.
