A visual comparison, with clear limits.

Pagepair compares corresponding rendered pages. It does not align moved pages or perform semantic text comparison. Page shifts, font rendering and antialiasing can appear as changes. Review the original files before publication or print.

Saved work stays protected.

When the library cannot be read, adding and deleting pause. Retry loading without replacing the saved index. The 1.0.1 update also keeps failed saves out of history and resumes unfinished deletion cleanup.
