Trim lines, collapse spaces, remove empty lines, or strip all whitespace — all in your browser, no upload, instant results.
About the Whitespace Remover
This whitespace remover runs entirely in your browser. Paste any text, then pick a cleanup action to apply instantly. Nothing is uploaded to a server — all processing happens locally with JavaScript on your device.
Cleanup actions
- Trim Lines — Removes leading and trailing whitespace from every line, but keeps the text inside each line intact.
- Collapse Spaces — Replaces every run of whitespace (spaces, tabs, line breaks) with a single space, producing one continuous line of text.
- Remove All Whitespace — Strips every whitespace character entirely, leaving only non-whitespace characters with no separators.
- Remove Empty Lines — Deletes lines that are empty or contain only whitespace, keeping the non-empty lines in order.
How to use the tool
- Paste your text into the input box.
- Click one of the cleanup buttons — the result appears in the output box.
- Click Copy result to copy the output to your clipboard, or Clear to start over.
Frequently asked questions
Does this tool upload my text? No. All processing happens locally in your browser. Your text never leaves your device.
What counts as whitespace? Spaces, tabs, line breaks, and other Unicode whitespace characters are all recognized.
Can I apply multiple actions? Yes. After applying one action, the result stays in the output box. You can copy it back to the input and apply another action, or run actions on the original input repeatedly.
Is there a length limit? The only limit is your browser's available memory. Even very long documents clean up instantly.
