Flatten PDF for authors
Updated July 2026
Arthize lets authors and self-publishers flatten a PDF in a private workspace — free, with no watermark. Flattening a PDF merges form fields, annotations and layers into the page, so nobody can change filled-in values and the file renders everywhere.
Why authors flatten a PDF
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 flatten pdf keeps the work inside your private workspace. Unpublished manuscripts are valuable IP; private processing keeps them off public servers.
What matters when you flatten a PDF
Flattening bakes form fields and annotations into the page so they can't be changed.
It fixes forms that display differently in different viewers.
A flattened PDF is the safe way to share a completed form.
