How to open a playlist file online

Inspect or convert
Check quality levels and segments, copy the links, or save the playlist in another format.
What is a .ASX file?
Lists of songs, videos, radio stations or stream segments.
An ASX file is a small XML text file (Advanced Stream Redirector) made by Microsoft. It holds no audio or video - only URLs pointing to media streams. Open it with VLC or Windows Media Player; if the stream URL is dead, nothing plays. Open it in Notepad first to inspect the link inside.

Frequently asked questions
Does this viewer play my .ASX file?
Only if you ask it to. Opening a playlist never connects anywhere. Each web link has a play button; the first time you press it we tell you which server it will contact.
Why can't some tracks be played?
Entries like C:\Music\song.mp3 or album/track.mp3 point to files on the computer where the playlist was created. They're flagged as Local path or Relative path.
What do the HLS quality levels mean?
A master .m3u8 offers the same video at several resolutions and bitrates. The player picks one based on your connection. We list them with resolution, bitrate and decoded codec names such as H.264 High or AAC-LC.
Is an IPTV playlist legal?
The file format is neutral. Whether the streams in it are licensed depends on the provider. We only show the list; we don't host or check streams.
Can I convert M3U to PLS or XSPF?
Yes. Titles, durations and locations are kept. HLS manifests are exported as a list of their variant or segment links.
