What is the Print Cost Calculator?

It is a utility that estimates the money, sheets, and ink volume you save by removing blank and duplicate pages before sending files to a physical printer.

Can it identify duplicate pages?

Yes, it computes visual hashes of page layouts to group pages that are duplicates or near-duplicates, allowing you to clean redundant slides or documents easily.

Will deleting blank pages affect layout structure?

No, the tool compiles a fresh PDF using WebAssembly, retaining links, annotations, and formatting on the remaining pages.
