**Category:** Text
**Keywords:** remove, blank, lines, empty, whitespace, clean, text, strip

## When to use this tool

Blank lines have a habit of appearing in text you didn't write yourself. Common situations where this tool saves time:

- **Copied web content**: Text copied from articles and websites often includes extra spacing between paragraphs that becomes double or triple blank lines when pasted into a document or editor.
- **Exported reports**: CSV files, database exports, and report outputs frequently include blank separator rows that need to be removed before further processing.
- **Code cleanup**: Logs, code snippets, and configuration files often accumulate excessive blank lines that reduce readability or cause parsing issues.
- **Email threads**: Copied email conversations typically contain large gaps between quoted sections.
- **Data preparation**: Before importing text into a spreadsheet, CMS, or other tool, removing blank lines ensures clean row-by-row processing.
- **Markdown and documentation**: Collapsing multiple blank lines into none makes documents easier to edit and reduces file size.

## How to use

1. Paste your text into the input box
2. Choose whether to also remove whitespace-only lines (lines containing only spaces or tabs)
3. Click "Remove Blank Lines"
4. Review the cleaned result in the output box
5. Click "Copy" to copy the result to your clipboard

## Understanding the options

**Remove whitespace-only lines** is enabled by default. This catches lines that look blank but actually contain invisible characters like spaces or tabs. These are common in copied content and exported files, and they usually should be treated as blank.

If you disable this option, only lines with zero characters are removed. A line with a single space is kept as-is. This is useful when your text intentionally uses indented blank lines as structure (for example, some programming languages use indentation-sensitive formatting).

## FAQs

**
**Q:** What counts as a blank line?**


**A:** A line with no characters at all. When you press Enter twice in a row, the line between the two presses is blank.

**
**Q:** What is a whitespace-only line?**


**A:** A line that contains only spaces, tabs, or other invisible characters but no actual content. These lines look blank when reading text but are technically not empty. The "Also remove whitespace-only lines" option removes these as well as truly empty lines.

**
**Q:** Will this change the content of non-blank lines?**


**A:** No. Only blank or whitespace-only lines are removed. Every line with actual content is kept exactly as written, including its spacing and formatting.

**
**Q:** Is there a size limit?**


**A:** The tool runs entirely in your browser, so there is no server-side limit. Very large texts (millions of characters) may slow down depending on your device, but typical documents and data exports work instantly.

**
**Q:** Does this tool store my text?**


**A:** No. Everything runs locally in your browser. Your text is never sent to any server.

**
**Q:** What do the stats mean?**


**A:** After processing, the tool shows three numbers: the total line count before cleaning, the line count after cleaning, and the number of lines removed. This helps you confirm the tool did what you expected.
