Remove Empty Lines
Remove Empty Lines deletes blank and whitespace-only lines from your text. You can remove every empty line, or collapse runs of blank lines down to a single separator, and optionally trim trailing spaces from each line.
It runs in your browser, so pasted logs, code and documents stay private.

Remove all vs. collapse blanks
By default, every empty or whitespace-only line is deleted, leaving a tight block of text. If your content uses blank lines to separate paragraphs, switch on "collapse to single blank line" instead — that removes excess spacing while keeping one blank line between sections.
Leading and trailing blank lines are removed in collapse mode so the result starts and ends with real content.
Why blank lines pile up
Copy-pasting from PDFs, emails and web pages frequently introduces stray blank lines, and exported data often ships with extra spacing. Cleaning these up makes text easier to read, smaller to store and tidier to paste into code or spreadsheets.
To also remove duplicate content, pair this with the Remove Duplicate Lines tool.
Frequently asked questions
- Does it remove lines that contain only spaces?
- Yes. Whitespace-only lines are treated as empty and removed (or collapsed) along with truly blank lines.
- Can I keep one blank line between paragraphs?
- Yes. Turn on "collapse to single blank line" to reduce runs of blanks to a single separator instead of deleting them all.
- Is anything uploaded?
- No. The text is processed entirely in your browser.
