Free M3U Playlist Editor Online

Upload the file or paste its contents. Every entry is parsed and laid out in a table you can work in: rename, regroup, reorder, delete. Thousands of channels are handled in a background worker, so the page keeps responding while a large file loads.

Nothing leaves the browser. You edit M3U playlists in your browser in the literal sense: the file is parsed on your own machine and written back out only when you ask for it. The original on disk is never touched.

Names, mostly. A provider export gives you entries like US: News One HD |S1| and a channel list full of those is unreadable at a glance. Renaming is the single change that makes a playlist feel like yours.

After that: groups, because two sources rarely agree on what to call the same category. Then order, so the channels you watch are not at position four hundred. Then deletion, which is usually the largest edit by count and the quickest to make.

Sort by group first. It turns an undifferentiated wall of channels into something with shape, and it makes the duplicates obvious. Filter to narrow further. Then work group by group rather than top to bottom, which is how a forty-thousand-entry file becomes an hour instead of an afternoon.

If the list needs pruning rather than tidying, do that first: the duplicate remover collapses repeats and the playlist cleaner drops entries that no longer answer. Editing what is left is a much smaller job.
