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.
