Flatten PDF for teachers

Updated July 2026

Arthize lets teachers and educators flatten a PDF in a private workspace — free, with no watermark. Flattening a PDF merges form fields, annotations and layers into the page, so nobody can change filled-in values and the file renders everywhere.

Why teachers flatten 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 flatten 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 flatten a PDF

Flattening bakes form fields and annotations into the page so they can't be changed.

It fixes forms that display differently in different viewers.

A flattened PDF is the safe way to share a completed form.
