You can detect duplicates by exact URL match (recommended, most accurate since different channels can have the same name) or by channel name (useful for catching the same channel on different servers). Enable both for thorough deduplication.

How to merge M3U playlists
Add two files, or ten. They are concatenated in the order you give them, and the result is one playlist you can download or open straight in the player. Nothing is uploaded: the merge happens in this tab.
Duplicate detection methods
Duplicates are the reason merging by hand is miserable. Two providers carrying the same channel give you the same thing twice under two spellings, and a naive concatenation keeps both. Matching by URL catches the exact same address appearing twice. Matching by name catches the same channel arriving from two different hosts. Use both when the sources overlap heavily, which they usually do.
Organizing groups after merging
Group names rarely agree between sources. One file says News, another says NEWS | UK, a third leaves the attribute off entirely. The merged file keeps whatever each entry declared, so the tidying is a separate job: open the result in the playlist editor and rename groups in bulk there.
When merging is the right move
Two subscriptions, one player. A curated list plus a regional one. A backup source you want folded in without losing the original. All of these are merges rather than replacements, and doing them in a text editor is where the duplicate channels creep in unnoticed.
Before and after
Merging multiplies whatever was already wrong in each source. Dead entries in two files become dead entries in one bigger file. Run the pieces through the stream checker first, or the whole result through the playlist cleaner afterwards. Either way the order matters less than doing it at all.
Which copy survives
When two files carry the same channel, the copy that survives is the one that appeared first. That is worth arranging deliberately rather than discovering afterwards.
Put your best-maintained source first and the surviving entry is the one with the sensible name, the right group, and a logo that loads. Put the bulk list first and you keep whatever it happened to call the channel. Same output size either way, very different list to actually use.
What happens to the headers
A valid playlist opens with a single #EXTM3U line. Concatenating files in a text editor leaves one of those in the middle of the result, which some players tolerate and others treat as the end of the list. The merge here writes one header at the top and drops the rest, so the output is a single well-formed file rather than several stapled together.
Frequently Asked Questions
How does duplicate detection work?
Is there a limit on how many playlists I can merge?
No, you can merge as many playlists as you like. Click 'Add Another Playlist' to add more input slots. Each playlist can contain any number of channels.
What happens to channel logos and EPG IDs during merge?
All metadata is preserved. Each channel keeps its original name, logo URL, group, and EPG ID. When duplicates are removed, the first occurrence's metadata is kept.
Can I merge playlists from different IPTV providers?
Yes, this is one of the most common use cases. Each playlist is parsed independently, so different providers' formats are handled correctly. Use the group prefix option to keep each provider's channels identifiable.
