Whitespace Normalizer
Paste text, choose the whitespace rules to apply, and copy the normalized result.
A QUICK WALKTHROUGH
How to use this tool
- Paste up to 1 MB of text.
- Choose trimming, space, newline, and blank-line rules.
- Normalize locally and copy the result.
Explicit whitespace policy
Line endings CRLF and CR become LF. Trim lines uses JavaScript String.trim() on every line, which removes ECMAScript Unicode whitespace and line terminators at each line edge. Collapse spaces affects ASCII space (U+0020) only; Tabs to spaces converts U+0009 tabs to one ASCII space. Other Unicode whitespace is preserved unless trimming removes it at a line edge.
Lines and blank lines
Collapse newlines changes consecutive LF characters to one LF. Remove blank lines removes lines that contain only Unicode whitespace after line-ending normalization; it does not remove meaningful text.
Local processing
Input is limited to 1 MB of text and stays in this browser. No upload, language detection, translation, or semantic rewriting is performed.
GOOD TO KNOW
Common questions
Which line endings are recognized?
CRLF and CR are normalized to LF, and existing LF is preserved.
Does collapsing spaces change every Unicode space?
No. It collapses ASCII spaces and tabs only. JavaScript trim still recognizes ECMAScript Unicode whitespace at edges.
Can blank lines be removed?
Yes. Enable Remove blank lines to drop lines that contain only Unicode whitespace.
