About this tool
About this tool
Whitespace Cleaner normalizes spaces, tabs, and line endings by trimming edges, collapsing consecutive spaces, and standardizing line breaks locally in your browser. Cleaned text remains editable for further steps.
Normalize spaces, tabs, blank lines, and line endings. Use the full-width workspace to clean and normalize content while reviewing lines, words, characters, whitespace, and Unicode content. The tool accepts plain text, provides focused options, and creates plain text output that you can inspect, copy, download, or save as a local draft.
Built for daily work
- Use Whitespace Cleaner for editing, publishing, data preparation, and everyday text cleanup.
- Remove routine quality problems while preserving useful data before content is imported, published, committed, shared, or passed to another application.
- Check a small sample interactively before applying the same operation to a larger plain text workflow.
- Prepare cleaner plain text output for teammates, clients, documentation, testing, or downstream automation.

Key features
Key features
Strip trailing spaces and tabs
Remove invisible trailing characters from every line, cleaning up text that has accumulated whitespace from editing, copying, or auto-formatting.

Reduce runs of two or more spaces down to a single space within each line, fixing text that has inconsistent internal spacing.
Leading whitespace removal
Strip indentation or leading spaces from every line when you want to remove all left-side whitespace, useful for reformatting pasted content.
Change summary with line counts
The report shows how many lines had trailing whitespace removed, how many had internal spaces collapsed, and the total lines processed.

Limitations and important notes
Limitations and important notes
- Review normalized values before importing them into another system.
- Large or deeply structured input depends on available browser memory and may process more slowly on mobile devices.
- The tool implements practical browser-based processing and may not reproduce every feature of specialist desktop software or every vendor-specific extension.
- Keep the original source and review generated output before production, security-sensitive, financial, legal, or safety-critical use.
