常见问题
What counts as an empty line?
Any line that's completely blank, or that only contains whitespace (spaces, tabs). Lines with visible text stay untouched, even if they're short.
Does it change the order or content of the remaining lines?
No, the remaining lines keep their original order and content. Only the blank lines are removed, nothing else is rewritten.
Is my text sent anywhere?
No, this runs entirely in your browser with plain JavaScript string processing. Nothing is sent to a server.
