Good to know
Paste the text contents of each file. Compare lines in their original order, including whitespace. Browser text boxes normalize line endings, so this is not a byte-for-byte comparison of the original files. Added lines start with +, removed lines with - (hyphen), and unchanged lines with two spaces. Missing final newlines are marked. This compares text only, with a one-million-character combined limit and a bounded processing time. Nothing is uploaded, saved or executed.
Example: A contains apple and pear; B contains apple and plum. The report keeps apple, removes pear and adds plum.
