Free tools for M3U, M3U8 & IPTV playlists

An M3U file is a plain-text playlist format originally created for Winamp. It contains a list of media file paths or stream URLs, one per line, with optional metadata tags like channel names and logos. M3U files are now the standard format for IPTV playlists and streaming media. The M3U playlist format is widely supported by media players, IPTV apps, and streaming platforms.

M3U is a generic playlist format for media files and live streams. M3U8 is the UTF-8 encoded variant used by Apple's HLS (HTTP Live Streaming) protocol. M3U8 files describe segmented video streams and include segment URLs, duration metadata, encryption keys, and adaptive bitrate information — not just a simple list of channels. Both M3U playlists and M3U8 playlists use similar syntax but serve different streaming purposes.

Yes. All M3U tools on M3U.codes run entirely in your browser using JavaScript. Your M3U playlist file is never uploaded to any server. Your stream URLs, IPTV credentials, and playlist data stay completely private on your device. This makes our M3U validator and M3U editor tools 100% secure for testing IPTV playlists.

The most common causes are: malformed EXTINF tags, incorrect URL encoding in stream addresses, missing or misspelled tvg-id attributes, expired IPTV subscription URLs, or streams that have gone offline. Use the M3U Validator tool to identify the exact syntax errors in your M3U playlist. Our M3U playlist troubleshooting guide covers how to fix these common M3U file errors. If your subscription keeps expiring, consider a reliable provider like <a href="https://faviptv.com/" rel="sponsored nofollow" style="color:var(--primary);text-decoration:underline">FAVIPTV</a> for stable, long-term service.

Yes. The M3U Merger tool lets you upload or paste two or more M3U files and combines them into a single M3U playlist. It automatically detects and removes duplicate entries based on stream URL, ensuring your merged IPTV playlist remains clean and organized. You can merge unlimited M3U playlists for free.

EXTINF is the extended information tag in M3U playlists. It appears before each stream URL and contains the duration (or -1 for live streams) and a comma-separated display name. Additional attributes like tvg-id, tvg-logo, tvg-name, and group-title are embedded as key-value pairs in the EXTINF line. Understanding EXTINF tags is essential for editing M3U playlists correctly.

M3U.codes offers five free M3U tools: M3U Validator (checks syntax errors), M3U Editor (modify channels and metadata), M3U Merger (combine multiple playlists), M3U Converter (convert between formats), and Playlist Analyzer (get detailed statistics). All M3U tools work directly in your browser with no installation required.

Start by running your M3U playlist through our M3U Validator to identify specific errors. Common fixes include: correcting malformed EXTINF tags, fixing URL encoding issues, updating expired stream URLs, removing duplicate channels, and ensuring proper UTF-8 encoding. Our M3U Editor tool makes fixing these issues quick and easy without manually editing text.
