Frequently Asked Questions
Why is invisible whitespace a problem?
Invisible whitespace causes issues in code (syntax errors), data processing (failed matches), and text formatting (weird spacing). Mixed tabs/spaces break code indentation. Trailing spaces clutter version control diffs. Zero-width characters from copy-paste break string comparisons.
Can it preserve line breaks?
Yes, replaces horizontal whitespace only.
Does it handle Unicode and special characters?
Yes, the tool fully supports Unicode characters including Chinese, Japanese, Korean, and emoji.
How do I remove extra whitespace from text?
Paste your text and choose which cleanups to apply: collapsing consecutive spaces into one, trimming the start and end of each line, removing empty lines, converting tabs to spaces, and normalizing line endings to LF or CRLF. Several can be combined at once, and the result shows the character and line counts before and after so you can see how much was removed. Everything runs locally in your browser.
