Frequently Asked Questions
Why use this diff checker compared to others?
Many online diff tools transmit your text to a server to compute the difference, posing a significant security risk for proprietary code or secret documents. Our tool uses a client-side text-differencing algorithm, ensuring your data never leaves your computer.
Can it compare source code?
Yes! It is highly effective for developers wanting to compare source code files without opening an IDE, providing clear line-by-line differences.
Is there a file size limit?
Because the tool uses your browser's memory, the only limit is the capability of your local device. It effortlessly handles standard documents and code files.
