Remove Blank Lines from Text Online

What this tool does

This tool reads your text line by line and removes every line that contains nothing — or nothing but spaces and tabs. The content of your remaining lines is never changed; only the empty gaps between them are removed.

Remove all blank lines strips every blank line from the output, so all your content lines run together with no gaps. Collapse multiple blank lines to one reduces any run of two or more consecutive blank lines down to a single blank line, which is useful when you want to keep paragraph spacing but remove duplicate gaps. Leading and trailing blank lines are removed in both modes.

The Count lines with only spaces or tabs as blank option — on by default — catches lines that look empty on screen but contain hidden whitespace characters. Trim whitespace from the start and end of each line also strips leading and trailing spaces from every content line in the output; when this option is on, whitespace-only lines are always treated as blank regardless of the other setting.

This tool does not join lines together. Each content line remains a separate line in the output; only the blank lines between them are removed. If you need to join hard-wrapped lines back into flowing paragraphs, use the Line Break Remover instead.

Common uses

Extra blank lines accumulate in pasted text from many sources:

• Copied lists and bullet points. Lists pasted from documents or note apps often carry blank lines between every item, making them hard to scan or paste elsewhere.
• Email threads. Forwarded emails and chat logs pick up blank lines between quoted blocks, signatures, and attribution lines.
• Log files and terminal output. Application logs and shell output regularly include blank separator lines that add visual noise without adding information.
• CSV and TSV rows. Exported data sometimes includes blank rows between sections that break CSV parsers or spreadsheet imports.
• AI chat output. Responses from AI assistants are often formatted with a blank line after every point, which looks heavy when pasted into a document.
• Notes from Word, documents, or email. If you copied plain text from a Word document, an email, or a spreadsheet and it contains extra blank lines, paste that text here to remove them quickly.

After removing blank lines, you can remove any repeated content lines with the Duplicate Line Remover, or reorder the result with Sort Lines (which also has its own blank-line removal option when sorting).

Blank Line Remover vs. Line Break Remover

These two tools solve different problems and should not be confused:

• Blank Line Remover (this tool) removes or collapses the empty lines between your content lines. Each content line stays on its own line — nothing is joined together. Use it when your text has too many gaps between lines.
• Line Break Remover joins hard-wrapped lines inside a paragraph into one continuous line of text. It treats blank lines as paragraph boundaries and preserves them. Use it when a paragraph has been broken into short lines that should flow as one sentence.
