# Annotate PDF for freelancers

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

Arthize lets freelancers and independent professionals 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 freelancers annotate 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 annotate 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 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.

2. **Add your PDF** — Upload the document to mark up.
