DiffForge uses the jsdiff library to compare text at three levels: line-by-line (shows entire lines added/removed), word-by-word (highlights changes within lines), and character-by-character (shows smallest possible changes). Removed pieces are highlighted in red, added pieces in green.
Both! Paste text directly into the two panels, or click 'Upload' to load text from files. The tool supports .txt, .js, .html, .css, .json, .md, .py, .ts, and more.
No. All text comparisons happen entirely in your browser. Nothing you paste or upload is ever sent to any server. DiffForge is safe for comparing confidential code or documents.
Yes! Click the 'Swap' button to exchange the contents of the left and right panels. This is useful when you accidentally paste text in the wrong panel or want to reverse the comparison direction.
