How to use

1. Open the live demo or run index.html locally.
2. Click Open or drop .m3u / .m3u8 files onto the page. Several files are merged into one playlist.
3. Use the top search box to find channels in every group. Switching groups keeps the selected channels.
4. Edit groups, channels, URLs, and metadata. Export saves the whole editor project; Import restores it.
5. Select several channels and click Rename to add a prefix or suffix, replace text, or add numbers. Double-click still renames one channel.
6. Select channels and click Check to test only those channels.
7. Use Sort to sort channels A-Z or by status.
8. Click Save M3U when you are done.

Run locally

git clone https://github.com/arazgray/awesome-m3u-editor.git
cd awesome-m3u-editor

Then open index.html in your browser.

Privacy

Awesome M3U Editor works locally in your browser. Your playlist is not sent to a server.

Notes about status checking

Browser-based checking has limits. Some IPTV servers block browser status checks with CORS. When that happens, the app shows CORS instead of guessing whether the stream is alive or dead.
