Public DemoWhat is M3U Playlist Checker
M3U Playlist Checker is a browser-first page for working with M3U and M3U8 playlist text in a controlled, lawful workflow. It is designed for operators, creators, schools, clubs, and support teams that need predictable playlist checks without adding unnecessary moving parts.
- Catch malformed M3U lines before they reach users or devices.
- Find repeated stream URLs and inconsistent channel naming.
- Review group-title, tvg-name, tvg-logo, and readable channel labels.
- Open compatible streams in the M3U8 player for quick verification.
- Work with playlist text in the browser without a server upload queue.
- Use clear copy that avoids piracy claims and respects source permissions.
How it works
This page does not provide premium channels, keys, account bypasses, or instructions for unauthorized access.
- Paste an M3U/M3U8 URL or playlist text from a source you are allowed to use.
- Review channels, metadata, groups, URLs, and player compatibility warnings.
- Copy the cleaned result or open valid streams in a compatible player.

Frequently asked
Does M3U Playlist Checker provide IPTV channels?
No. It helps you inspect, organize, or play playlists you already have permission to use. It does not sell or unlock channels.
Are playlists uploaded?
No. The intended workflow keeps playlist text in the browser session unless a future page explicitly says otherwise.
Can it fix every broken stream?
No. Some streams expire, require headers, block browser playback, or are no longer available from the source.
Is M3U the same as M3U8?
M3U is the playlist format family. M3U8 is the UTF-8 variant commonly used for HLS streaming.
What should I do with copyrighted streams?
Do not use unauthorized streams. Verify the source, license, and access rights before testing or sharing a playlist.
