Watermark PDF for authors

Updated July 2026

Arthize lets authors and self-publishers add a watermark to a PDF in a private workspace — free, with no watermark. Adding a watermark stamps text or an image — like DRAFT or CONFIDENTIAL — across every page at the opacity and angle you choose.

Why authors add a watermark to 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 watermark pdf keeps the work inside your private workspace. Unpublished manuscripts are valuable IP; private processing keeps them off public servers.

What matters when you add a watermark to a PDF

A watermark can be text or an image applied across every page.

Opacity and angle control how prominent the mark is.

Watermarks are useful for marking drafts and confidential copies.
