Clean whitespace

Copied text often carries invisible noise: double spaces, tabs, trailing whitespace at line ends and surplus blank lines. They look harmless but break layouts, distort comparisons and bloat files. This tool tidies your text and makes it clean and consistent again.

You decide what gets cleaned: trim whitespace at line ends, collapse repeated spaces into one, remove blank lines and convert tabs to spaces. Line endings are handled uniformly, whether the text comes from Windows, Mac or Linux. Each option can be toggled on its own, so you get exactly the cleanup you want.

The whole cleanup runs entirely locally in your browser in pure JavaScript - your text is not uploaded, not stored, and no foreign library is loaded from a CDN. You can download the result as a text file or copy it straight out.

Specifications

In 3 steps

1. Paste the text into the text field.
2. Choose what to clean (trim, collapse, blank lines, tabs).
3. Read the cleaned text or download it as a text file.

Limitations: Only whitespace is cleaned (spaces, tabs, line breaks); the actual content stays unchanged. Leading indentation is lost when trimming is active - so use it with care for source code where indentation matters. Very large texts are limited by your device memory.
