Frequently Asked Questions
Is this text diff tool completely free?
Yes! Our text diff tool is 100% free with no registration required, no watermarks, and no hidden fees. Compare unlimited text files anytime you need.
How does the text comparison work?
Our tool uses advanced diff algorithms (similar to Git diff and Unix diff commands) to compare texts line by line using Longest Common Subsequence (LCS). It highlights additions in green, deletions in red, and provides detailed change statistics.
Is my data safe and private?
Absolutely! All text comparison happens entirely in your browser using JavaScript. Your text content never leaves your device, is never uploaded to our servers, and is never stored anywhere. Perfect for comparing confidential documents.
What file formats can I compare?
You can compare any plain text content including source code files (JavaScript, Python, Java, HTML, CSS, etc.), documents (TXT, CSV), data files (JSON, XML, YAML), configuration files, and any other text-based format. Simply copy and paste the content.
Can I ignore whitespace or case differences?
Yes! Our tool offers flexible comparison options: ignore whitespace changes (useful for code formatting differences), ignore case differences (for case-insensitive comparisons), and toggle line numbers. This helps you focus on meaningful content changes rather than formatting variations.
