Everything you need to know about StringDiff and how to use it effectively.
StringDiff is a powerful online tool that allows you to compare two text strings and instantly see the differences between them. It highlights additions, deletions, and modifications using color-coded visual indicators.
Our tool uses the jsdiff library, which implements advanced text comparison algorithms. It analyzes both texts character by character, word by word, or line by line (depending on the mode you choose) and identifies exactly where differences occur.
We offer three diff modes: Character mode (compares individual characters), Word mode (compares whole words), and Line mode (compares entire lines). Choose the mode that best fits your comparison needs.
Yes! You can upload text files (.txt, .md, .js, .ts, .jsx, .tsx, .py, .java, .cpp, .c, .html, .css, .json) directly into the text areas. The tool will read the file contents and load them for comparison.
Absolutely! All text processing happens entirely in your browser. No data is sent to our servers or stored anywhere. Your privacy is guaranteed - once you close the page or navigate away, all data is immediately discarded.
