How to use it
- Add your files. Drop AIFF files on the page or use Choose files. Folders and ZIPs work too.
- Check that WAV is selected. WAV 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 WAV without any loss.
Converting to a lossless format keeps the sound exactly as it is in the source; it cannot add back detail an earlier lossy encoding removed.
About AIFF and WAV
AIFF: AIFF is Apple’s uncompressed audio format, the Mac equivalent of WAV.
WAV: WAV is uncompressed audio: perfect quality and big files.
Questions
Is my AIFF file uploaded?
No. The conversion runs inside this browser tab, and the WAV 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 AIFF files at once?
Yes. Drop as many as you like, a folder or a ZIP; “Download all” saves every WAV in one ZIP.
