Get rid of extra blank lines (or collapse them down to one)
Two modes. Remove all strips every blank line, leaving just the lines that have actual content. Collapse squishes runs of consecutive blank lines into a single one, so you keep paragraph breaks without the triple-spacing mess.
Lines that contain only spaces or tabs count as empty too, not just truly blank ones. Your actual content lines stay exactly as they are.
Modes
- Remove all: every blank line gone, maximum compactness
- Collapse: multiple consecutive blank lines become one
- Lines with only whitespace are treated as empty
- Content lines are never touched
- Instant processing, one-click copy
- Browser-only, your text stays private
How to use it
Paste your text. Pick your mode. Click the button. Copy the result.
Say you’ve got a document where some sections have three or four blank lines between paragraphs. Collapse mode normalizes everything to single blank lines. Remove all mode pushes everything together with zero spacing. Pick whichever fits your needs.
When blank lines are a problem
Code linting: most linters have a rule about maximum consecutive blank lines (usually 1 or 2). If your file is full of excessive spacing, a quick collapse pass fixes it before you commit.
Text pasted from PDFs: PDF-to-text extraction is notorious for injecting random blank lines. Remove all mode cleans that up instantly.
Forwarded emails: by the time an email has been forwarded three times, there are blank lines everywhere. Clean it up before replying.
Data files: CSV, TSV, and log files sometimes have blank line padding from exports. Strip them before processing or importing.
Markdown: extra blank lines in Markdown don’t always render the way you’d expect. Collapse mode keeps your paragraph breaks (single blank lines) while removing the excess.
Config files: .env files and YAML configs accumulate blank lines over time. Not harmful, but messy.
For a comprehensive cleanup, combine this with the Text Trimmer (leading/trailing whitespace per line) and the Duplicate Line Remover (repeated lines). Those three tools cover most formatting problems.
If you need to deal with whitespace within lines rather than blank lines between them, the Text Trimmer is the right tool.
FAQ
What qualifies as an empty line?
A line that’s completely blank or contains only spaces/tabs. If there’s even one visible character, it’s kept.
When should I use collapse vs. remove all?
Collapse keeps paragraph structure, great for documents, articles, and Markdown. Remove all gives you the most compact output, better for data files and code blocks.
Does it catch lines with only spaces?
Yes. Whitespace-only lines are treated as empty and get removed or collapsed alongside truly blank lines.
Can I chain this with other cleanup tools?
Definitely. Empty Line Remover + Text Trimmer + Duplicate Line Remover handles most text formatting issues you’ll encounter.
Is it private?
Yes. All processing runs in your browser. Nothing is transmitted.
