Annotate PDF for freelancers
Updated July 2026
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.
