Annotate PDF for teachers

Updated July 2026

Arthize lets teachers and educators 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 teachers annotate a PDF

Before class a teacher merges a reading and a worksheet into one handout, prints four slides per sheet to save paper, and adds page numbers so students can follow along — all without a watermark.

Built for worksheets. Whether it's worksheets, lesson plans, handouts, Arthize's annotate pdf keeps the work inside your private workspace. Grade sheets and student information are sensitive. A private workspace keeps class records off public servers.

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.
