_Updated July 2026 · Arthize · https://arthize.com/for/nonprofits/annotate-pdf_

Arthize lets nonprofit and NGO teams annotate a PDF in a private workspace — free, with no watermark. Annotating a PDF adds highlights, comments, shapes and notes on top of the page, so you can mark up a document without changing its text.

## Why nonprofits annotate 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 annotate 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 annotate a PDF

Annotations sit on top of the page and don't change the underlying text.

You can highlight, comment, draw and add notes.

Annotated files are ideal for review and feedback.
