Last updated
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?
Yes. ASF is a format most current software no longer opens, so converting it is the reliable way to keep watching it. MPG is a reasonable target; MP4 is the safest.
The picture is re-encoded
An ASF usually holds Windows Media video and audio. This writes MPEG-2 video with MP2 sound into the MPG. Both sides are compressed with loss, so this is a second generation: leave the quality at its default or higher, because the encoder is working from ASF artefacts rather than the original.
Where the MPG will play
MPG plays on Windows Media Player, VLC and DVD authoring software.

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. Restore Old Video removes it while converting.
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.
