Remove Empty Lines

Strip all blank lines from your text instantly, or collapse runs of consecutive empty lines down to a single blank line to preserve paragraph spacing. Blank lines frequently appear when copying from spreadsheets, PDFs, or email threads, making output look messier than intended. This tool cleans that up without touching the lines that actually have content.

Frequently Asked Questions

What counts as an empty line?
Any line that contains only whitespace — spaces or tabs — is treated as empty and removed.
Can I collapse multiple blank lines into one instead of removing all of them?
Yes — enable the "keep single blank lines" option to reduce runs of empty lines to a single blank line rather than removing them entirely.
Is there a limit to how much text it can process?
No server-side limit — all processing happens locally in your browser so it handles very large text blocks.
