How to Remove Blank Lines from Text or Code Online

To remove blank lines, paste your text into a browser tool like ByteTools Remove Empty Lines and it deletes every empty line at once, with an option to collapse extra gaps instead of erasing them entirely. Everything runs locally, so your content is never uploaded.

Text copied from a PDF, spreadsheet or web page almost always arrives full of unwanted gaps. Those blank lines break formatting, waste space and make documents look sloppy. Clearing them by hand is slow; a dedicated cleaner does it in a single step.

Why pasted text is full of blank lines

PDF viewers often add a line break after every visual line and an extra one between blocks, so pasted text ends up double-spaced. Spreadsheets and web pages introduce their own stray gaps. The result is text that scrolls forever and reads badly. Removing or collapsing the blank lines restores a normal, compact flow — useful for writers, developers cleaning up code, and anyone preparing content for another system.

How to remove empty lines in your browser

1. Paste your text into the input box.
2. Tick "Treat whitespace-only lines as empty" to also drop lines that contain just spaces or tabs.
3. Tick "Collapse blanks to one" if you want to keep a single blank line between paragraphs instead of removing every gap.
4. Copy the cleaned result or download it as a .txt file.

Remove all vs collapse: which mode do you want?

The two modes solve different problems. This table shows when to use each.

For an article or email, collapse mode is usually right — it kills the double-spacing while keeping one clean gap between paragraphs. For a data list, removing every blank gives you the most compact result.

Frequently asked questions

How do I remove blank lines from copied text?

Paste the text and the tool immediately deletes every empty line. If the copy also holds lines of invisible spaces or tabs, enable the whitespace-only option so those go too.

Can I keep one blank line between paragraphs?

Yes. Enable "Collapse blanks to one" and runs of two or more consecutive blanks are reduced to a single blank line, preserving your paragraph structure while removing the excess gaps.

What counts as an empty line?

By default only lines with no characters at all are removed. With the whitespace-only option on, lines containing just spaces or tabs — which look empty but technically are not — are treated as blank too.

Why does text from a PDF have so many empty lines?

PDF viewers often insert a line break after every visual line plus an extra between blocks, so pasted text becomes double-spaced. Removing or collapsing the blanks restores normal paragraph flow.

Is my text stored anywhere?

No. The tool runs entirely in your browser with JavaScript — nothing is transmitted, logged or saved — so it is safe for contracts, code and confidential documents.
