Quick answer: To extract AIFF audio from WEBM video, add the WEBM file to the iHateFiles WEBM to AIFF converter and press Convert. The conversion runs in your browser, so the file is never uploaded, and it is free with no sign-up, watermark or size limit. Lifts the soundtrack out of the video and saves it as AIFF. The picture is discarded; nothing is re-recorded.
Should you convert WEBM to AIFF?
Worth doing when you want the soundtrack of a WEBM on its own: a podcast, an interview, a piece of music from a video. Choose a higher bitrate than you think you need, because the AIFF is encoded from the video's audio rather than from a master.
Taking the sound out of WEBM
A WEBM file holds a picture track and a sound track side by side. This keeps the sound and discards the picture, so what you get is the AIFF on its own at whatever bitrate you choose. Nothing about the WEBM original is altered.

What usually goes wrong
About the WEBM. A browser screen recording is usually a WEBM with a broken duration, so players show it as zero seconds or refuse to seek. Converting it to MP4 rewrites the header and fixes the seeking.
About the AIFF. AIFF and WAV are the same audio at the same size; only the byte order and metadata differ. Converting between them changes nothing you can hear.
How to convert WEBM to AIFF
- Add your WEBM file. It is read from your disk and stays there.
- Check the settings. The output format is already set to AIFF.
- Press convert and the AIFF file is saved back to your device.
Questions
How do I convert WEBM to AIFF?
Open this page, add your WEBM file, and press convert. The file is decoded and re-encoded by your own browser and saved back to your device. Nothing is uploaded.
Is this WEBM to AIFF converter free?
Yes, completely. There is no account, no sign-in, no watermark and no daily limit, because there is no server doing the work. Your own device does it.
Are my files uploaded anywhere?
No. There is no upload endpoint. The conversion runs inside this browser tab, so your file never leaves your device. You can open your browser's network panel and watch: nothing carrying your file is sent.
Is there a file size limit?
No fixed limit. Because the work happens on your machine there is no server quota. The only ceiling is your own device's memory, which for video means very large files may be slow.
Does extracting audio reduce the quality?
The soundtrack is re-encoded to AIFF, so there is one generation of loss at the bitrate you choose. Pick a higher bitrate, or a lossless target like WAV or FLAC, to avoid it.
Can I convert several WEBM files at once?
Yes. Add as many as you like and they are converted one after another, then offered as a single ZIP.
