# Watermark PDF for freelancers

_Updated July 2026 · Arthize · https://arthize.com/for/freelancers/watermark-pdf_

Arthize lets freelancers and independent professionals 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 freelancers add a watermark to a PDF

A freelancer exports an invoice to PDF so it can't be edited, merges it with a proposal into one client packet, signs the contract on screen, and sends everything — without paying for Acrobat.

**Built for invoices.** Whether it's invoices, proposals, contracts, Arthize's watermark pdf keeps the work inside your private workspace. A freelancer's client contracts and invoices are private business records that don't belong on a free 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.
