Whitespace Cleaner is a messy text cleaner, processing happens locally in your browser with no upload.

Copying from web pages or documents often brings stray indentation, repeated spaces and blank lines. Cleaning first avoids subtle bugs downstream.

Paste or type your content into the input field at the top, or press the sample button to load demo data.
Adjust the options below the input, such as output format, separators, letter case or precision.
Press the main button to run the conversion. Results appear instantly in the output panel without a page reload.
When the result looks right, use the copy button in the corner, or download it as a local file.

Clean up stray spaces and line breaks before pasting for more accurate results.

Does it remove all spaces?+

No. Leading, trailing and repeated spaces are cleaned; single spaces between words are kept.

What about tabs?+

Tabs can be converted to spaces for consistent code alignment.

Is Whitespace Cleaner free to use?+

Yes. The tool is completely free with no usage limits, and you never need an account or a sign-in.

Is the text I enter uploaded anywhere?+

No. All processing runs locally in your browser, so the input never reaches a server and is never logged or stored.

Does Whitespace Cleaner work on a phone or tablet?+

Yes. The layout is mobile-first, so inputs and buttons stay comfortable on phones and tablets in both orientations.

Can I copy the result into my own document?+

Yes. A copy button in the output panel puts the result on your clipboard, and you can also download it as a text file.
