Password protect PDF files, Google Documents, Sheets, and Google Slides. Remove password protection from encrypted files.
Listing updated:June 23, 2023
Works with:
221K+
Overview
Easily protect any PDF file in your Google Drive with a password and add restrictions around printing, commenting, and annotations. Send the encrypted PDF files via email without leaving Google Drive.

The PDF toolbox can also password protect native Google file formats include Google Documents, Google Spreadsheets and Google Slides presentations. The files are first converted to PDF files and then encrypted with the specified password.

The Google Drive API can only export files that are 10 MB or less in size. Similar size restrictions thus apply to the PDF toolbox app as well.

PDF toolbox is developed by Amit Agarwal, the developer behind several popular Google Workspace add-ons including Mail Merge with Attachments, Document Studio and Google Forms Notifications.

The app is currently in beta and completely free during the beta period.

hardly ever works, cannot accurately determine file sizes - a complete failure as a tool

It's not working for me. Tells me my files are over 10 mb when they are as small as 4 mb and 7 mb. Uninstalling.

It's instrumental as an added layer of security in your files but It's aggravating that the native google drive files still needs to be converted into a PDF before being encrypted, the 10 MB limitation is also quite a bummer, overall this extension serves its purpose and it should be considered if you want an added layer of security.

My file is 7mb, you are telling me it's over 10mb so you can't do your job. As regular programmers do. Stuff that doesn't work as expected. Please warn people it doesn't do files over 10mb and avoid them useless installs. PG

Doesn't work at all. Addon installed ok, I followed directions, tells me to click on a PDF, but when I do, nothing happens. The Encrypt button does not appear. Useless.
