Whitespace Remover & Text Minifier
Remove extra whitespace, blank lines, and leading/trailing spaces from text. Free, instant.
How to use this tool
- Enter text to clean and mode in the fields above.
- Results update instantly as you type — or click Calculate.
- Read your cleaned text and the full breakdown beneath it.
Remove excess whitespace from text content — collapse multiple spaces, strip leading/trailing spaces from each line, or remove all spaces for minification.
How it works
The Whitespace Remover scans your pasted text and strips unwanted spaces according to the mode you choose. In Trim Lines mode it removes leading and trailing spaces from each line. In Collapse Spaces mode it replaces runs of two or more consecutive spaces with a single space. In Remove Blank Lines mode it deletes lines that contain nothing but whitespace.
You can combine modes to fully minify a block of text: trim edges, collapse internal gaps, and remove empty lines all at once. The cleaned result appears immediately so you can copy it without any page reload.
Common uses include cleaning up text copied from PDFs (which often introduces ragged indentation), normalising user input before storage, and shrinking config or data files by removing decorative whitespace that adds no meaning.
No text is sent to a server. Processing happens entirely in your browser, so you can safely paste confidential content.
Worked examples
Clean up copy-pasted PDF text
- Copy a paragraph from a PDF that has extra spaces mid-sentence.
- Paste it into the 'Text to clean' box.
- Select the 'Collapse Spaces' mode.
- Click Clean — double spaces collapse to single spaces.
- Copy the tidy result.
A readable paragraph with single spaces throughout, ready to paste into a document.
Minify a plain-text config file
- Paste the config text into the input box.
- Select 'Remove Blank Lines' and 'Trim Lines' together.
- Click Clean.
- Copy the condensed output.
A compact config block with no blank separators or leading indentation, saving bytes.
Common mistakes to avoid
- Pasting code with intentional indentation and choosing Trim Lines mode — this strips the indentation, breaking Python or YAML files.
- Expecting the tool to remove single spaces between words; it only collapses runs of two or more spaces.
- Forgetting to select any mode — without a mode selected nothing is changed and the output looks identical to the input.
