Remove Empty Lines Online

When text is copied from documents, emails, or log files, extra blank lines tend to pile up between paragraphs or data rows. Some look empty but actually contain spaces or tab characters. Paste your text here to strip every blank gap, with the option to remove only fully empty lines or whitespace-only lines too. Nothing is uploaded.

About This Tool

How it works

Paste your text into the left panel. Choose your removal mode, hit run, and copy the cleaned output. The tool works line by line, identifying and removing every line that qualifies as empty under your chosen setting, while leaving all lines that contain actual content untouched.

The two removal modes

Remove all empty lines targets any line that contains nothing at all, just a bare newline character with no content on either side. This is the standard mode for cleaning up paragraphs, log output, and exported documents where the blank rows are genuinely empty.

Remove whitespace-only lines goes a step further. Some lines look blank on screen but contain one or more spaces or tab characters that are invisible. These lines pass through a standard empty-line check undetected. This mode catches and removes those as well. If your text has lines that appear empty but are not being removed, switching to this mode will handle them. You can also run the text through the remove extra spaces tool first to normalise any stray whitespace before stripping the empty lines.

Where empty lines come from

Copy-pasting from PDFs is the most common cause. PDF converters frequently insert blank lines between every paragraph, between list items, and sometimes between individual sentences depending on the original layout.

Log files and exported data tend to use blank lines as visual separators between records or sections. When you pull that data into a text editor or paste it into another tool, those separators come with it.

Email threads add blank lines through quoting and forwarding. Each level of reply adds its own formatting, and blank lines accumulate between quoted blocks.

Code and config files sometimes pick up blank lines during editing or merging. Some languages and tools have conventions around blank line limits, so stripping extras is part of standard cleanup before committing or deploying.

Common questions

An empty line contains nothing except the newline character that ends it. A whitespace-only line contains one or more spaces or tabs that are invisible on screen but technically present as characters. Both look the same visually but behave differently when processed by parsers, scripts, or other tools.
Yes, if your paragraphs are separated by a single blank line, that line will be removed. If you want to keep intentional paragraph gaps, use a word processor or the remove line breaks tool with the preserve paragraphs option instead.
No. The tool only removes lines that are completely empty or whitespace-only depending on your mode. Every line that contains actual text, numbers, or characters stays exactly as it is.
Yes, and that is a common workflow. Remove the empty lines here first, then run the output through the remove duplicate lines tool to get a clean, unique list.
