Why Clean
The details that make a difference
Keep paragraphs
Blank lines can stay as paragraph boundaries while single line breaks disappear.
Choose the replacement
Use spaces for prose, nothing for split identifiers, or your own separator.
No rewriting
Punctuation and words stay unchanged. Hyphens are never removed automatically.
Before
A sentence split across two lines. Another paragraph.
After
A sentence split across two lines. Another paragraph.

Frequently asked questions
Is this tool free?
Yes. Clean is free, with no account, payment or download gate.
Is my data uploaded?
No. Processing happens in your browser. Your input is not sent to our servers, sold, shared or used for AI training. Large inputs are limited by your device’s available memory.
Can I keep paragraph breaks?
Yes. Enable Keep paragraphs to retain blank-line boundaries while joining lines within each paragraph.
Does it work with Windows line endings?
Yes. Windows CRLF, Unix LF and old-Mac CR are normalized before processing.
Can I remove breaks without spaces?
Yes. Choose Nothing. Be aware that adjacent words will join together.
Does it fix words split by hyphens?
No. Hyphens may be intentional, so the tool does not silently remove or rewrite them.
