Introduction:
While we attach great importance to PDF document security, such as bank statements and medical records, we may be confronted by their password protection as well. We all know that PDF documents can be easily secured with a password. However, password protection can be a hindrance in PDF editing if you do not know the password. Therefore, how do we remove passwords from PDFs?
summary

In this article, when we refer to password, it means permission password (used to limit certain actions such as printing) instead of open password (used to open the PDF). With an open password, no one can access the PDF document. We will introduce several PDF password removers to remove password protection from PDFs for easier editing and printing.

However, we need to be aware that Google Drive is only a cloud storage platform, instead of a professional PDF password remover, its document management capacity largely relies on Google Docs. The password-protected PDF document opened by Google Docs may have misformatted layout and misused fonts due to different encoded formats.

Note:  Though Drive can be a feasible method to remove password protection from PDF documents online, it is obviously not the best option and as seen, the aforementioned PDF password crackers outperform Drive.  

Conclusion

What requires special attention is that all the previously mentioned PDF password removers can only handle PDFs protected by PERMISSION PASSWORD (owner password) rather than OPEN PASSWORD (user password). The former is to limit editing, copying, printing, and annotating while the latter password is to restrict the opening of a PDF file.

There is no related program that can bypass the OPEN PASSWORD restriction as removing an open password is illegal without authorization. All listed tools are able to remove the permission password to let users edit or make annotations on the file.
