How to Password Protect a PDF on Chromebook

Encrypt a PDF with a password on Chromebook — no extension, no Android app, just the Chrome browser.

Chromebook's built-in PDF viewer (the Files app) does not encrypt PDFs. FixMyPDF fills this gap — open the tool in Chrome, set a password, done.

Steps on Chromebook

Open Chrome. Go to fixmypdf.in/tools/protect. Click Choose File and select your PDF. Enter a password. Click Protect. Download to Downloads folder.

For School or Work Chromebooks

No installation required. FixMyPDF is a standard website accessible on managed Chromebooks without administrator approval.

What Encryption Level Is Used?

AES-256, the same standard used by government and financial institutions. Strong enough for personal and business use.
