Whitespace Cleaner
Clean, trim, and normalize whitespace in text, code, articles, or data. Trim leading and trailing spaces, collapse multiple blanks, convert tabs to spaces, and flatten lines 100% client-side.
Zero-Lag Normalization
Blazing fast regex-optimized string streaming handles large logs and markdown files instantly without UI stutter.
Configurable Indentation
Convert tab stops to 2, 4, or 8 spaces, collapse blank lines, or flatten entire multi-line blocks into single strings.
100% Client-Side Privacy
Confidential documents, proprietary code, and secret tokens never touch a server. Processing executes purely in browser memory.
Whitespace Cleaning Tips
Clean Git Diffs
Enable 'Trim Trailing Whitespace' before committing code to avoid unnecessary line changes in pull requests and git diffs.
Tab vs Space Standards
Use 'Tabs → 2 Spaces' for JavaScript, TypeScript, HTML, and JSON projects, or 'Tabs → 4 Spaces' for Python and Java codebases.
Show Invisible Characters
Toggle 'Show Invisible Characters' to visually differentiate regular spaces (·) from tab characters (→) and line breaks (↵).
100% Client-Side Privacy
All whitespace processing and conversion are executed locally in your browser memory. No sensitive text or code is ever sent to a server.

Frequently Asked Questions
How does the Whitespace Cleaner sanitize text?
Our cleaner evaluates text line by line, stripping trailing spaces, collapsing redundant internal spaces, standardizing indentations (tabs to spaces or vice versa), and normalizing line breaks with instant sub-millisecond execution.
Can I convert tabs to spaces for my codebase?
Yes! Choose either the 'Tabs → 2 Spaces' or 'Tabs → 4 Spaces' preset, or manually set your tab width to 2, 4, or 8 spaces in the options panel.
What does the 'Show Invisible Characters' option do?
It visualizes normally invisible formatting markers: regular spaces appear as centered dots (·), tabs appear as arrows (→), and line breaks appear as carriage returns (↵), making it easy to identify hidden spacing issues.
Is any part of my text or code uploaded to an external server?
No. All text parsing, tab replacement, and whitespace stripping happen strictly in-memory inside your web browser. Neither your text, code, nor tokens ever leave your computer.
