Clean whitespace
Whitespace cleanup runs in your browser.
Why this tool works well
- Three cleanup modes for common whitespace issues.
- Fast copy and clear actions for editing workflows.
- No data leaves your browser during processing.
- Text copied from PDFs frequently contains line breaks in the middle of sentences and irregular spacing where the PDF renderer inserted breaks for layout. Clean it up here before using it in a document.
- When preparing data for import into a database or spreadsheet, trailing whitespace in field values causes silent mismatches in equality checks and joins. Clean the data before import to avoid those issues.

Suggested workflow
FAQ
Can I trim each line separately?
Yes, use the Trim each line action.
Will this remove all line breaks?
No, only when specific cleanup mode requires it.
Does the tool remove intentional indentation?
The default mode collapses multiple spaces to single spaces and trims line edges, which does remove leading indentation. If you need to preserve code indentation, use the trim-only mode which only removes trailing spaces from each line.
What counts as whitespace in this tool?
Regular spaces, non-breaking spaces, tabs, and sequences of multiple spaces are all treated as whitespace and normalised according to the selected mode.
