Arthize lets marketing 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 marketers add a watermark to a PDF

A marketer exports a deck to PDF so fonts don't shift, compresses the case study for an email send, and converts key pages to images for a social post — all without a watermark.

**Built for decks.** Whether it's decks, one-pagers, case studies, Arthize's watermark pdf keeps the work inside your private workspace. Unreleased campaigns and client materials are confidential and shouldn't sit on a public server.

## 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.
