How to use it
- Add your files. Drop WAV files on the page or use Choose files. Folders and ZIPs work too.
- Check that AAC is selected. AAC is already chosen on this page.
- Adjust options if you need to. Quality, size and other settings appear when the format has them.
- Convert and download. Press Convert; with several files, “Download all” gives you one ZIP.
What happens to your file
The audio is decoded and encoded as AAC at the bit rate you choose.
AAC is lossy, so pick a bit rate at least as high as the original’s to avoid audible loss.
About WAV and AAC
WAV: WAV is uncompressed audio: perfect quality and big files.
AAC: AAC is the lossy audio codec of Apple, YouTube and most phones; it sounds better than MP3 at the same size.
Questions
Is my WAV file uploaded?
No. The conversion runs inside this browser tab, and the AAC is created on your device. Nothing is sent to a server.
Is there a file size limit?
No fixed limit: files are processed by your device, so very large videos depend on its memory. Computers handle several GB; phones are best with smaller files.
Can I convert several WAV files at once?
Yes. Drop as many as you like, a folder or a ZIP; “Download all” saves every AAC in one ZIP.
