Whitespace Cleaner
Strip extra spaces, tabs, and line breaks in one click
Paste in messy text and clean up the duplicate spaces, stray tabs, and unwanted line breaks with a single click. It's handy for normalizing code indentation to spaces or tabs, or collapsing document data onto one line. All processing happens entirely in your browser, so the text you paste never leaves your device.

FAQ
- Can I apply more than one cleanup at once?
- Each button applies one transformation at a time, but you can paste the result back into the input box and click another button to chain them together.
- Is my text stored on a server?
- No. Every transformation runs locally in your browser — nothing is uploaded or saved anywhere.
- Can I use it to convert tabs to spaces in code?
- Yes. The Tab ➔ 4 Spaces button swaps each tab character for four spaces, and the 4 Spaces ➔ Tab button converts them back.
