常见问题
What does the text report show?
Lines that are only in the first file are red, lines only in the second file are green, and changed words inside a line are highlighted. Unchanged text is folded to keep the report short.
What does the visual comparison show?
Each page that differs is drawn three times side by side: first file, second file, and a map where changed pixels are red. Tiny anti-aliasing differences are ignored.
Does it work with scans?
The visual comparison does. The text report needs real text in the files; scans have none.
Is anything uploaded?
No. Both files are compared inside your browser.
