Frequently asked questions

What counts as a blank line?
A blank line is any line that contains no characters, or contains only whitespace (spaces, tabs). Lines with actual content are never removed.
What is the difference between the two modes?
'Remove all blank lines' strips every empty line, merging all text together with no gaps. 'Collapse to single blank line' removes extra blank lines but keeps one between sections, preserving paragraph formatting.
What does 'trim trailing whitespace' do?
Trailing whitespace is invisible spaces or tabs at the end of a line. Enabling this option removes them before checking if a line is blank — so a line containing only spaces will be treated as empty and removed.
Will this remove blank lines inside code blocks?
Yes — the tool processes all lines equally. If you need blank lines preserved in certain sections, paste only the relevant portion.
Is my text uploaded or stored?
No. All processing happens in your browser using JavaScript. Your text never leaves your device.

The Kordu Remove Empty Lines tool cleans up text with unwanted blank lines

in two ways. "Remove all blank lines" strips every empty or whitespace-only

line from the text — useful when you've pasted content from a PDF, web page,

or code editor that added extra line breaks throughout. "Collapse to single blank

line" is more conservative — it removes consecutive blank lines but keeps one,

which preserves paragraph spacing in prose.

An optional "trim trailing whitespace" toggle removes invisible trailing spaces

from every line before processing. Lines that look empty but contain spaces will

be treated as blank with this option enabled.

Stats below the output show how many lines were removed so you can verify the

result. Copy the cleaned text in one click.

All processing runs client-side in your browser. Your text is never uploaded,

stored, or transmitted to any server.
