Text Cleaner

Text Cleaner removes common spacing noise from pasted text. Options can trim the beginning and end of every line, collapse horizontal whitespace within lines, and reduce runs of three or more line feeds to two.

The cleaner first converts Windows CRLF pairs to line feeds. Regardless of the selected options, the final result is trimmed at both ends. It does not repair grammar, join wrapped lines, normalize all Unicode, or identify document structure.

Text copied from documents, PDFs, chats, and exports often contains trailing spaces, uneven gaps, or too many blank lines. Cleaning those artifacts makes the text easier to edit and paste elsewhere.

• Remove indentation and trailing spaces when line trimming is enabled.
• Turn repeated horizontal whitespace into one ordinary space.
• Limit blank-line runs to a single blank line.
• Normalize common Windows line endings.

CRLF sequences become LF first. If trim-lines is enabled, each LF-separated line uses JavaScript `trim()`, which removes leading and trailing Unicode whitespace. If collapse-spaces is enabled, each run matched as non-line-feed whitespace becomes one regular space. This includes tabs and carriage returns that were not part of CRLF.

If collapse-blank-lines is enabled, any run of at least three consecutive line feeds becomes exactly two. Finally, the entire result is trimmed even when line trimming is turned off.

Two consecutive line feeds represent one empty line and are preserved by blank-line collapse. Lines containing spaces may become truly empty if line trimming or space collapsing is enabled, but the blank-line rule only looks at consecutive line feeds at its stage in the pipeline.

Indentation can be meaningful in code, poetry, Markdown, tables, or outlines. Turning on trim-lines or collapse-spaces can damage that structure. The tool offers a preview so options can be evaluated before copying.

Clean whitespace improves consistency and prevents accidental formatting differences. Selective cleaning is safer than assuming every extra space is an error, especially with structured or preformatted text.

The cleaner applies enabled replacements in a fixed order: line-ending normalization, line trimming, horizontal whitespace collapse, blank-line collapse, then unconditional outer trimming.

CRLF normalize → selected cleanup options → trim whole result

Horizontal whitespace

Whitespace other than line feed.

Blank-line run

Three or more consecutive line feeds.

Text Cleaner handles common whitespace problems with three focused options. Review structured content carefully, because indentation and repeated spaces can carry meaning.
