Purpose and use
Visually check layout and image changes between selected pages of two PDF revisions.
Example
Compare page 1 of A with page 2 of B when a revision changes the page order.
Interpreting the result
Pages are rendered at 72 PPI. Different page dimensions remain visibly different.
Limits and caveats
This is not a semantic text diff or print color proof. Fonts and transparency depend on PDF.js rendering.

Frequently asked questions
Will this change the original file?
No. Downloads are separate files. Closing the page discards the loaded content and results.
