Trim Whitespace Online - Fast & Accurate Text Cleaner | CleanUpTxt
Got text with weird extra spaces at the beginning or end of lines? Whether it came from a copy-paste mess or a code export, cleaning that up manually is the worst. The Trim Lines tool trims leading and trailing whitespace from every line in a snap - all right in your browser.
The Problem
When you copy text from PDFs, websites, or code editors, each line can end up with random spaces or tabs in front or at the end. These invisible characters cause headaches when lining up formatting or preparing text for other tools. For example, if you're importing into a spreadsheet or code parser, those hidden spaces can break everything.
How to Use the Trim Lines
The Trim Lines tool instantly removes leading and trailing whitespace from every line in your text. It doesn't touch your content, line structure, or spacing between words - just trims the bits you can’t see but definitely notice when things don’t align. And since it runs fully in your browser, it's private and blazing fast.
Detailed Explanation
Trim Lines operates line by line, identifying and stripping out any space, tab, or other whitespace character at the beginning or end of each line. It doesn’t change punctuation, capitalization, or content between words. It’s often used before importing cleaned text into other tools or applications where hidden spaces create formatting or data issues. It runs entirely in your browser, so none of your text is ever uploaded or stored - ideal for sensitive data or private notes. If a line contains only whitespace, it becomes an empty line, which you can clean out using Remove Empty Lines. For deeper formatting tweaks, Find & Replace helps you adjust internal spaces or structure.

What does 'trim lines' actually remove?
[Trim Lines](/tools/trim-lines) removes only leading and trailing whitespace from each line. That means spaces, tabs, and invisible padding characters before the first or after the last visible character.
Does it remove spaces between words?
Nope! It doesn't touch inner spacing. If you need to collapse or remove inner extra spaces, try [Find & Replace](/tools/find-replace) instead.
Can it handle lines with just spaces or tabs?
Yes - lines made entirely of whitespace will be converted into empty lines. You can clean those up further with [Remove Empty Lines](/tools/remove-empty-lines).
What about full paragraphs or multiline content?
Each line is trimmed independently. If you want to clean up full paragraphs, make sure your text is broken into lines or use [Remove Line Breaks](/tools/remove-line-breaks) beforehand to flatten it.
