About whitespace cleanup

Invisible whitespace characters — trailing spaces, mixed tabs and spaces, inconsistent line endings (CRLF vs LF), and excessive blank lines — cause unnecessary noise in version control diffs and can introduce subtle bugs in whitespace-sensitive contexts like Python, YAML, and Makefiles.

This tool strips trailing whitespace, normalizes line endings, collapses consecutive blank lines, and optionally converts between tabs and spaces. It processes the text entirely in the browser.
