It depends on the number of channels. We check multiple channels simultaneously, a 500-channel playlist typically takes 30-60 seconds, and a 2000-channel playlist takes 2-4 minutes.

How to clean M3U playlists
Upload a file. Every address in it is requested, and you get a list split into what answered and what did not. Remove the failures, download the rest. That is the whole job.
How the checking process works
Requests go out in parallel with a timeout, because a list of several thousand entries checked one at a time would take longer than anyone will wait. A slow host can therefore be reported as dead when it was merely slow, which is worth knowing before you delete a channel you liked. Re-check a suspicious result on its own with the stream checker before dropping it for good.
Best practices for playlist maintenance
Playlists rot. Hosts move, tokens expire, providers reshuffle, and a file that worked last month quietly fills with entries that go nowhere. A monthly pass is usually enough.
What cleaning cannot fix
A cleaner removes what fails. It does not remove what is redundant: the same channel listed four times under four spellings still passes every check, because all four addresses answer. That is a different problem and the duplicate remover is the tool for it. Nor does it reorganise anything, which is the editor.
What "dead" actually means here
A dead result means the request did not come back with something playable. That covers several different underlying causes, and they are not equally permanent.
A 404 or a refused connection is usually final. A timeout might just be a slow host under load. A 403 often means the stream is geo-restricted rather than gone, so it is alive for somebody, just not for you from here. And a provider that rate-limits will start refusing partway through a large check, which makes everything after a certain point look dead when it is not.
That last one is worth watching for: if failures suddenly cluster at the end of the list, re-run the check on a smaller slice before deleting anything.
What counts as dead
A channel is marked dead when its address does not answer inside the timeout. That is a narrower claim than it looks, and worth understanding before deleting anything on the strength of it.
That last case is the one to be careful with. If an entire group comes back dead at once, suspect the host’s policy before concluding the group is gone.
- No answer at all. The request failed or timed out, and the source is usually gone.
- An answer that is not a stream. Some hosts return a courtesy page rather than a 404 when a channel ends, and that counts as dead here.
- A refused cross-origin request. A browser cannot tell this apart from a dead source. The stream may be perfectly alive and simply not readable from a web page.
What it will not decide for you
It reports, and it removes what you tell it to. It does not judge picture quality, it does not remove duplicates, and it does not rank anything. A channel answering instantly with a poor picture is alive as far as this tool is concerned, and one taking four seconds over a distant connection can be marked dead while being merely far away.
Raise the timeout before deleting in bulk if the list spans several continents. The default suits a local source and is unkind to a remote one.
Frequently Asked Questions
How long does the cleaning process take?
Why might a working channel show as dead?
Some streams require specific user agents, authentication tokens, or geographic restrictions. These may appear dead in browser-based checking but work fine in dedicated IPTV player apps. If you suspect this, try the channel in the player itself before removing it.
Can I undo the removal after downloading?
The cleaner never modifies your original file. It creates a new cleaned version for download. Your original playlist file remains unchanged on your device, so you can always re-process it.
What happens to 'Server Reachable' channels?
Server Reachable channels are kept in the cleaned playlist. They responded to our probe, which means the server is online. They just don't allow browser-based content reading due to CORS policy, which is completely normal for IPTV streams.
A channel plays in VLC but came back dead here. Why?
Almost always the cross-origin header. A desktop player is not bound by the rule a browser enforces, so it reaches sources a web page cannot. The stream is fine and this tool simply cannot see it.
Does checking make the playlist smaller on its own?
No. Checking reports what it found and changes nothing. Entries are removed only when you ask for it, and the file on your disk is untouched until you export.
