What is Empty Line Remover?

An empty line remover strips all blank lines from a block of text. A line is considered empty if it contains nothing or only whitespace characters (spaces, tabs). Lines with visible content are preserved as-is. The result is the same text with all gaps closed up — paragraphs run together, code blocks compact, lists tighten.

This online tool is useful for cleaning up code output, log files, copy-pasted text from PDFs or web pages, and any document where excessive blank lines reduce readability. It is the fastest way to remove empty lines online without writing a regex or using the command line.

For more granular whitespace control (collapsing spaces, trimming line ends, normalizing line endings), use the [Whitespace Cleaner](/tools/whitespace-cleaner/). To remove duplicate non-empty lines, see the [Duplicate Line Remover](/tools/duplicate-line-remover/).

FAQ

Does it remove lines with only spaces or tabs?
Yes. Lines that contain only whitespace characters are treated as empty and removed.
Can I keep single blank lines but remove consecutive ones?
This tool removes all blank lines. For more granular control, use the Whitespace Cleaner which offers multiple cleaning options.
Does this tool also remove lines that contain only spaces or tabs?
Yes. The tool treats lines that contain only whitespace characters (spaces, tabs) as empty and removes them, not just lines with zero characters.
How can I remove empty lines on the command line?
On Linux/macOS: `sed -i '/^$/d' file.txt` removes lines that are completely empty. To also remove lines containing only whitespace: `sed -i '/^[[:space:]]*$/d' file.txt`. With `awk`: `awk 'NF' file.txt`. With `grep`: `grep -v '^$' file.txt`. For one-off cleaning in the browser, this online tool is faster than scripting.
