Watermark PDF for architects

Updated July 2026

Arthize lets architecture teams 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 architects add a watermark to a PDF

An architect merges plan sheets and schedules into one issue set, compares two drawing revisions for changes, and exports key sheets to images for a client presentation.

Built for plan sets. Whether it's plan sets, schedules, specifications, Arthize's watermark pdf keeps the work inside your private workspace. Designs and client plans are proprietary; private processing protects the practice's work.

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.
