Remove Whitespace

This text sanitization tool strips unnecessary whitespace characters from your input text, handling spaces, tabs, newlines, carriage returns, and non-breaking spaces. The processor uses a multi-pass regex engine to identify and remove different categories of whitespace according to your selected mode: remove all whitespace, trim leading and trailing spaces only, collapse multiple spaces into single spaces, or remove blank lines while preserving paragraph structure.

The tool processes text through the browser's native JavaScript string manipulation functions, which handle Unicode whitespace categories correctly, including less common characters like em spaces, en spaces, thin spaces, and zero-width spaces that standard find-and-replace operations often miss. You can preview changes before applying them, with a diff view highlighting exactly which characters will be removed.

Programmers cleaning up code formatting, data analysts preparing CSV imports, writers fixing copy-paste artifacts from PDFs, and web developers sanitizing user input all rely on this utility. The entire operation runs locally in your browser with no text data sent to any server, making it safe for processing sensitive documents, credentials, or proprietary content.
