What is the Text Diff?
Designed for speed and privacy, the Text Diff manipulates text instantly in your browser with zero data transfer directly inside your web browser. Compare two texts and highlight differences. There is no need to install software, register an account, or upload anything to a third-party server — everything happens on your own device for maximum data security.
The Text Diff is one of more than 150 free utilities available on NOFYI, all sharing the same privacy-first architecture. It is grouped under Text Tools because it shares the same workflow patterns as the other tools in that category — open the page, supply your input, and copy or download the result.
How to Use the Text Diff

Tips for Best Results
Power users typically keep the Text Diff open in a pinned browser tab alongside their other daily tools. To get the most out of it, experiment with the available options — small tweaks to quality, size, or format can produce dramatically different results. When in doubt, run a quick test on a small input first, then scale up once you are happy with the output.
