About This Tool
This tool removes only lines that meet the selected blank-line rule. By default, lines containing only spaces or tabs also count as blank. Other lines keep their surrounding whitespace unless you explicitly turn on trimming.
How to Use It
- Paste multiline text that contains blank lines.
- Choose whether to remove whitespace-only lines; this is on by default.
- Turn on Trim retained lines only if you also want to remove their leading and trailing whitespace.
- Click Remove Empty Lines, check the counts, and copy or download the TXT result.
Examples
- a, a blank line, b, another blank line, c → a, b, c.
- Lines containing only spaces or tabs are removed by default.
- The nonempty line “ title ” keeps its surrounding spaces by default.
Rules and Limits
CRLF, CR, and LF are normalized before filtering. A completely empty line has zero characters; whitespace-only mode also matches Unicode whitespace. Trimming retained lines is off by default. Output uses LF and does not automatically collapse spaces within a line.
Common Uses
- Clean blank separators out of exported lists.
- Tidy up log excerpts or copied text.
- Preserve indentation in code, settings, or paragraphs.

FAQ
What counts as an empty line?
A completely empty line contains no characters. By default, the tool also removes lines containing only spaces, tabs, or other Unicode whitespace.
How do I keep lines that contain only spaces?
Turn off Remove whitespace-only lines. Only lines with zero characters will be removed.
Will other text change?
By default, nonempty lines are not trimmed and internal spaces are preserved. Line endings are normalized to LF.
Why is trimming a separate option?
Trimming changes the leading and trailing whitespace of nonempty lines. It is a separate operation, so it stays off until you choose it.
