Watermark PDF for nonprofits

Updated July 2026

Why nonprofits add a watermark to a PDF

A nonprofit merges its narrative report with financial statements into one grant submission, signs the board approval remotely, and compresses the package to meet a funder's upload limit — free.

Built for grant reports. Whether it's grant reports, financial statements, board minutes, Arthize's watermark pdf keeps the work inside your private workspace. Donor and beneficiary data is sensitive; nonprofits need private processing without a costly subscription.

What matters when you add a watermark to a PDF

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