About this tool
Compare two texts line by line, see added and removed content with line numbers, and download the differences.
How to use
Enter the original text on the left and the updated text on the right, or open a file on each side. Matching lines are aligned, so inserting one line does not mark every later line as changed.
Comparison is case- and whitespace-sensitive; CRLF and CR are normalized to LF. Each input allows 3,000 lines and 256 KiB, with a maximum line-count product of 4 million. Downloads use +, - and a space to mark line changes.
Switch between side-by-side and unified views. Changed characters are highlighted within paired lines. Collapse long unchanged sections, expand them when needed, and jump between changes. Ignoring trailing whitespace is optional; other whitespace and letter case still matter. The download always includes the full comparison.
