Unlock PDF for students
Updated July 2026
Arthize lets students unlock a PDF in a private workspace — free, with no watermark. Unlocking a PDF removes a known password or usage restrictions from a document you own, so it opens and prints without prompting.
Why students unlock a PDF
The night before a deadline, a student merges lecture slides with their notes, compresses a scanned reading under the portal's 10MB limit, and annotates the key pages for revision — free, with no watermark on the result.
Built for lecture slides. Whether it's lecture slides, readings, assignments, Arthize's unlock pdf keeps the work inside your private workspace. Students often work on shared or library computers; a tool that processes files privately and deletes them keeps coursework and ID scans out of strangers' hands.
What matters when you unlock a PDF
Unlocking requires the current password — it removes protection you are entitled to remove.
It is used to clear a known password so a file stops prompting on every open.
Arthize does not crack unknown passwords on documents you don't own.
