Frequently Asked Questions
What is the difference between Line, Word, and Character diff modes?
Line mode compares texts line by line, ideal for code or structured documents. Word mode compares individual words, useful for prose and documentation. Character mode compares every single character, perfect for finding subtle typos or encoding differences.
Is my text data secure when using this tool?
Absolutely! All text comparison is performed entirely in your browser using JavaScript. Your text data is never sent to any server, ensuring complete privacy. You can even use this tool offline once the page is loaded.
Can I compare large text files?
Yes, this tool can handle reasonably large texts. However, for extremely large files (several MB), performance may vary depending on your browser and device. For best results with very large files, consider using line mode which is more efficient.
What do the colors in the diff result mean?
Green highlighted text with a '+' prefix indicates content that was added in the modified text. Red highlighted text with a '-' prefix shows content that was removed from the original. Unhighlighted text remains unchanged between the two versions.
Can I use this tool for comparing code?
Yes! This text diff tool works great for comparing code snippets, configuration files, SQL queries, and any programming-related text. The line-by-line mode is particularly useful for code comparison as it preserves the structure.
