Quick answer: To convert ASF to MPG, add the ASF file to the iHateFiles ASF to MPG 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. ASF is a format most software has stopped opening. MPG is not.
Should you convert ASF to MPG?
A safe conversion: ASF and MPG are both lossless, so this is a change of container rather than a change to the picture.
Nothing is discarded
ASF and MPG are both lossless, so every pixel survives the move intact. Convert back and forth as often as you like; the image does not degrade.

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 MPG. An MPG from a DVD is interlaced, so it shows comb-like horizontal tearing on movement when played on a computer. Deinterlacing during conversion fixes it.
How to convert ASF to MPG
- Add your ASF file. It is read from your disk and stays there.
- Check the settings. The output format is already set to MPG.
- Press convert and the MPG file is saved back to your device.
Questions
How do I convert ASF to MPG?
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 MPG 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.
Will converting to MPG lose quality?
MPG is a lossy format, so some detail is discarded. The quality control on this page decides how much. The default is set high enough that most people cannot see the difference.
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.
