Annotate PDF for small businesses
Updated July 2026
Arthize lets small business owners and 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 small businesses annotate a PDF
A small business merges the month's receipts into one file, converts a proposal to PDF for a client, and password-protects a sensitive contract before emailing it — on a free plan with no per-seat cost.
Built for invoices. Whether it's invoices, contracts, receipts, Arthize's annotate pdf keeps the work inside your private workspace. A small business's financial and client documents are confidential and shouldn't be retained by a free ad-funded tool.
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.
