Use this Remove Empty Lines tool to clean up text by deleting blank lines, including lines that contain only whitespace such as spaces or tabs. This is useful when you copy content that has random gaps, prepare lists for import, clean log files, or tidy up code snippets before sharing.
The tool works line-by-line. Lines with real content are preserved, even if the line only contains a single character. If you want more control, use paragraph-friendly options like keeping a single blank line between paragraphs or collapsing multiple blank lines into one. These toggles help you clean formatting without turning text into one dense block.

Remove blank lines (including whitespace-only lines) with optional paragraph-friendly collapse.
How to remove empty lines from text
- Paste your text into the input box (or upload a file).

Examples
Remove blank lines from a list
apple banana cherry
apple banana cherry
Collapse multiple blank lines to one

Paragraph 1 Paragraph 2
Options
- Remove whitespace-only lines (spaces/tabs)
- Trim non-empty lines (optional)
- Collapse multiple empty lines into one (preserve paragraphs)
- Stats (lines before/after, removed count)
Troubleshooting
- Blank lines still remain: they may contain spaces or tabs; enable whitespace-only removal.
- Output looks too tight: use collapse/keep-one-blank mode to preserve paragraph spacing.
- Weird line breaks: copied text may include CRLF vs LF differences; paste again and retry.
- Invisible characters: trim non-empty lines to reduce hidden whitespace issues.
Common questions
Does this remove whitespace-only lines too?
Yes. Enable “Remove whitespace-only lines (spaces/tabs)”. This treats lines that only contain spaces or tabs as empty.
Can I keep one blank line between paragraphs?
Yes. Choose a blank line mode that collapses blank runs and keep the “Keep one blank line between paragraphs” option enabled.
Can I collapse multiple blank lines into one?
Yes. Choose “Collapse multiple blanks into one” to preserve paragraphs while removing extra blank lines.
Does this tool trim spaces on non-empty lines?
Optionally, yes. Use “Trim non-empty lines” to remove leading/trailing whitespace from content lines.
Will this change the order of lines?
No. It only removes or collapses blank lines; it does not reorder content lines.
Does it work with code and logs?
Yes. It’s often used to clean pasted logs and code blocks before sharing or importing.
Can I upload a file and download the result?
Yes. Use Upload File to load text and Download to export the cleaned output.
How does it handle tabs?
Tabs are treated as whitespace. If whitespace-only removal is enabled, a tab-only line is considered empty.
Does it support very large text?
It works best for typical copy/paste sized inputs. For very large files, consider splitting into chunks.
Is my text uploaded to a server?
No. The cleanup runs in your browser; your text stays on your device.
