Collapse U+0020 only
Repeated-space cleanup reduces runs of two or more regular U+0020 spaces to one. NBSP, full-width spaces, and zero-width spaces remain unchanged by default.

CLEANUP GUIDE
Whitespace and line-ending cleanup guide
These notes explain regular spaces, tabs, per-line trimming, blank lines, and exact LF/CRLF output for pasted text.Trim each line separately
The tool removes leading and trailing horizontal whitespace on every line rather than only trimming the document edges. Text content and line order stay intact.
Tab removal is deletion
TAB (U+0009) characters are deleted, so review tables, code, or text where tabs separate words or columns.
Blank-line removal is optional
Lines that are empty after cleanup can be removed. Turn this option off when blank lines intentionally separate paragraphs.
LF and CRLF are code formats
Mixed CRLF, CR, and LF input is normalized internally, then emitted as LF or CRLF. This does not join or delete lines.
Verify CRLF in TXT bytes
A browser textarea may visually normalize line endings. When exact Windows-style CRLF matters, use the downloaded TXT result as the reference.
IMPORTANT NOTES
Important notes
- Whitespace-sensitive code, ASCII art, and tables can change structure after cleanup.
- Normalize line endings does not join or delete lines.
- NBSP (U+00A0), full-width space (U+3000), and zero-width space (U+200B) are not changed by default.
- Removing tabs can join words because TAB characters are actually deleted.
- The service limit is 1,000,000 input characters.
FAQ
Frequently asked questions
01Does it remove every line break?+
No. Line-ending normalization only makes CRLF, CR, and LF codes consistent.
02Will paragraphs remain if blank-line removal is off?+
Yes. Other cleanup options do not delete the lines themselves.
03Can words join after removing tabs?+
Yes. TAB characters are deleted, so review the result.
04Is my text or uploaded file sent to a server?+
No. Typed text, TXT/MD/CSV files, and the cleaned result are processed locally in your browser.
05Can I save Windows-style line endings?+
Yes. Choose CRLF and download the TXT file.
