When you try to edit a PDF with a password, a warning screen appears and you cannot edit it.

This page shows you how to edit a password-protected PDF on a Mac, but you can do it on Windows as well.

The method is to use cloud storage such as “Microsoft OneDrive” or “Google Drive”.

When you try to edit a PDF with a password, the warning screen appears and you cannot edit it.

Without the owner password, you do not have permission to create or modify annotations in the documents.

Enter the password to unlock annotation of the document.

I searched for apps that can unlock the password, but I couldn’t find them so far.

Using cloud storage instead of the apps made it easy to unlock the password, so I will introduce them from the following.

Method 1: Using Microsoft OneDrive

Personal Cloud Storage – Microsoft OneDrive
Save your files and photos to OneDrive and access them from any device, anywhere. Learn more and get 5 GB of free personal cloud storage today.

Assuming that you have already created an account on Microsoft OneDrive and can use it, I will introduce the procedure from the following.

The work flow is as follows.

  • Uploading a PDF
  • Downloading the pages you want to edit in PDF format with the print command

▶ Upload the PDF to a suitable location on OneDrive.

Microsoft OneDrive

▶ After uploading the PDF, click to view the contents.

OneDrive PDF

▶ From the OneDrive menu bar, click “Print”.

▶ When the print instruction screen is displayed, make settings such as specifying the pages to output and click the print button.

The screen below is for Mac, but a similar screen is displayed on Windows, so make the necessary settings and operate.

Method 2: Using Google Drive

Personal Cloud Storage & File Sharing Platform - Google
Learn about Google Drive’s file sharing platform that provides a personal, secure cloud storage option to share content with other users for free.

Assuming that you have already created an account on Google Drive and can use it, I will introduce the procedure from the following.

The work flow is as follows.

  • Installing of add-on app for PDF display
  • Uploading a PDF
  • Downloading the pages you want to edit in PDF format with the print command

▶ Open Google Drive and select “New” -> “Other” -> “Add App” from the upper left.

▶ When the apps installation screen is displayed, enter “pdf” in the search window to search, and install “PDF Viewer” from the search results.

The installation method is just as instructed on the screen, so it is omitted here.

Conclusion

In terms of ease of effort, OneDrive, which can be used as a standard function, is easier.

Also, Google Drive can install various apps with add-ons, but as far as I tried multiple, PDF apps with editing functions could not read PDFs with passwords.

The “PDF Viewer” introduced on this page does not have an editing function, so it seems to have worked well.
