Remove Whitespace Online

When text gets copied from PDFs, spreadsheets, HTML, or other sources, it often comes with extra spaces, tabs, and line breaks that need cleaning up. This tool strips excess whitespace from your text.

How it works

The tool processes your text client-side using JavaScript string methods and regular expressions. Depending on the mode you choose, it can collapse multiple spaces into one, remove leading/trailing whitespace, strip blank lines, or remove all whitespace entirely.

How to use it

1. Paste your text into the input area
2. Choose your whitespace removal mode:
   • Trim edges — removes leading and trailing spaces only
   • Collapse spaces — reduces multiple spaces/tabs to a single space
   • Remove blank lines — strips empty lines
   • Remove all whitespace — removes every space, tab, and newline
3. The cleaned text appears in the output panel
4. Click copy to grab the result

A few things worth knowing

• Tabs become spaces: In most modes, tab characters are treated as whitespace and collapsed to a single space. If you need to preserve tab indentation, use "Trim edges" mode only
• Line breaks: "Collapse spaces" mode does not remove line breaks between paragraphs — use "Remove blank lines" to clean those separately
• Non-breaking spaces: Some copy-pasted text contains non-breaking spaces ( ) that look like regular spaces but aren't. If whitespace seems stubborn, this may be why

FAQ

Why is there still a space after cleaning? If a character looks like a space but isn't being removed, it may be a non-breaking space or a zero-width character from a PDF or rich text source. Try the "Remove all whitespace" mode, or check the character in a hex viewer.

Will this change my text content? Only whitespace characters are affected — letters, numbers, and punctuation are untouched.

Can I use this to clean up code? For code formatting, use a dedicated formatter — CSS Formatter, XML Formatter, or JSON Formatter — which understand the language's syntax.
