How to compare two PDF files side by side or with an overlay
Load two PDF versions locally and inspect them page by page using side-by-side viewing or an adjustable visual overlay.
- Choose the first PDF version.
- Choose the second PDF version.
- Start the comparison.
- Switch between Side by Side and Overlay modes.
- Navigate page by page and adjust zoom or overlay opacity when you need a closer visual check.
A practical example
When a revised contract or report comes back, open the original and revised PDFs together. Read them side by side for broader review, then use the overlay to inspect small layout or visual changes.
Common questions
Does Compare PDF automatically understand legal text changes?
No. This is a visual PDF comparison workflow. It displays the documents side by side or as an overlay so you can inspect visible differences yourself.
What is overlay mode?
Overlay mode places the rendered versions together and lets you adjust opacity, which can make shifts and other visual differences easier to notice.
Can the PDFs have different page counts?
The viewer navigates through the available pages of the two documents, so inspect the complete comparison when document lengths differ.
Are both PDFs processed locally?
The comparison workflow loads and renders both PDFs in your browser.
