Compare PDF for authors
Updated July 2026
Arthize lets authors and self-publishers compare two PDFs in a private workspace — free, with no watermark. Comparing two PDFs highlights what changed between versions — added, removed and edited text — so you can review revisions at a glance.
Why authors compare two PDFs
An author merges manuscript chapters into one file, resizes the pages to the print trim size, and exports a clean, watermark-free PDF for the printer.
Built for manuscripts. Whether it's manuscripts, proofs, cover files, Arthize's compare pdf keeps the work inside your private workspace. Unpublished manuscripts are valuable IP; private processing keeps them off public servers.
