Frequently asked questions
Can teachers use this PDF editor for free in the classroom?
Yes — every tool is free, with no account, no trial period, and no limit on how many documents you edit.
How do I black out student names before sharing a document publicly?
Use the Blackout tool to drag a solid black rectangle over any name, grade, or other detail you want hidden before the file goes out.
Can I give feedback directly on a student's PDF assignment?
Yes — the Pen tool lets you write comments freehand anywhere on the page, and Highlighter lets you mark the specific passage you're referencing.
Is it safe to handle student records and forms in this editor?
Nothing is uploaded to a server — every edit happens locally in your browser. Still, always follow your school's own policies for handling student records; this tool keeps the file on your device, but the judgment about what's appropriate to share is still yours to make.
