Trim leading/trailing whitespace per line

Removes spaces and tabs at the start and end of every line

Collapse multiple spaces to one

Replaces runs of 2+ spaces with a single space

Convert tabs to spaces

Replaces each tab character with a single space

Remove blank lines

Removes empty or whitespace-only lines

Collapse multiple blank lines to one

About This Tool

The Whitespace Remover provides seven independent whitespace operations that can be combined in any order. Check the operations you need and the output updates instantly. Operations run in sequence from top to bottom: trim per line → collapse spaces → convert tabs → remove blank lines → collapse blank lines → ensure trailing newline → remove all whitespace.

The character count is shown for both input and output, along with the total number of characters removed. All processing is local in the browser.

How to Use

Use Cases

Developers clean up copy-pasted code that gained extra indentation or trailing spaces before committing to version control. Technical writers clean up exported document text that contains double-spaces or blank lines from word processors. Data engineers normalize whitespace in CSV or text fields before loading into a database. Bloggers clean up AI-generated text that has inconsistent spacing. DevOps engineers normalize config files to remove trailing whitespace that triggers linting warnings.

FAQ

What order do operations run in? — Operations run top-to-bottom in the order shown: trim → collapse spaces → convert tabs → remove blank lines → collapse blank lines → trailing newline → remove all. The order matters when operations interact (e.g., tabs are converted before spaces are collapsed).
Does "collapse multiple spaces" affect indentation? — Yes. If you use spaces for indentation, "collapse spaces" will reduce 4-space indents to single spaces. Use it only when indentation is not meaningful (prose text, not code).
Does the tool handle Windows line endings (CRLF)? — The browser normalizes line endings on paste. Output uses Unix-style LF. If you need CRLF, append a regex replace after copying.
What does "Remove ALL whitespace" do? — It strips every space, tab, newline, and other whitespace character, producing a single continuous string. Use this only when you need a compact, delimiter-free output.
