Quick answer: To extract AIFF audio from ASF video, add the ASF file to the iHateFiles ASF 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 ASF to AIFF?
Worth doing when you want the soundtrack of a ASF 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 ASF
A ASF 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 ASF original is altered.
ASF and AIFF side by side

What usually goes wrong
About the ASF. ASF, WMV and WMA all share the same file signature, so identifying which one you have means looking at the streams inside rather than the first few bytes.
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 ASF to AIFF
- Add your ASF 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 ASF to AIFF?
Open this page, add your ASF 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 ASF 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 ASF files at once?
Yes. Add as many as you like and they are converted one after another, then offered as a single ZIP.
