What is Blank Line Remover?

Blank Line Remover strips all empty or whitespace-only lines from your text instantly. Perfect for cleaning up code, data files, or pasted content that has too much vertical spacing.

Two blank-line modes handle different messes: Remove All strips every empty line so paragraphs sit flush, while Collapse to Single keeps one blank between blocks for readability. Tick Remove duplicate lines to also drop repeated entries in one pass — handy for lists of emails, URLs or keywords. The side-by-side comparison shows exactly which lines disappeared and tracks line and character counts, so you can verify nothing useful got cut before copying.

How to use

1. Paste or type your text with unwanted blank lines into the input area.
2. Choose whether to remove all blank lines or collapse multiple blanks into single ones.
3. Copy the cleaned output — all excess blank lines are gone instantly.

When to use

• Cleaning email or PDF copy-paste that arrived with triple line breaks between every sentence.
• Compacting code or config files where blank lines were inserted by a buggy formatter.
• Tidying CSV or log exports before pasting into a spreadsheet that hates empty rows.

Result

You've copied a code snippet from a website and it has triple-spaced lines everywhere. Paste it in, select 'Remove all blank lines', and get cleanly formatted code with no empty gaps.

FAQ

Does the tool also remove lines that contain only spaces or tabs?

Yes. A line counts as blank when it has nothing or only whitespace (spaces, tabs, no-break spaces). Lines with even a single visible character stay intact, including ASCII art using punctuation.

What is the difference between Remove All and Collapse to Single?

Remove All deletes every empty line, so paragraphs end up touching. Collapse to Single keeps one empty line between blocks of text, which is usually what you want for prose where paragraph separation matters.

Will my line endings (CRLF vs LF) be preserved?

Yes — use the Line endings selector to control them. Keep original leaves them as they are, or choose Unix (LF), Windows (CRLF), or Mac (CR) to standardise the whole file in one pass. Handy when moving code or config between platforms.

Is there a length limit on the text I can paste?

Practical limits depend on your device memory. A modern laptop handles a million lines without lag. Phones may slow down past 100k lines. Split very large logs into chunks if you see the comparison view stutter.

Does the tool send my text anywhere?

No. Cleaning runs entirely on your device. Pasted text stays in the page memory and disappears when you close the tab, so confidential drafts, legal notes, or proprietary code never leave your machine.
