1. Online Tools

There are several online tools available that claim to remove security from PDF files without a password. These tools use various techniques to bypass the security settings in the document. However, it is crucial to be cautious while using such tools as they may compromise the security and confidentiality of the document.

2. Google Chrome

It is important to note that attempting to remove security from a PDF file without proper authorization may be illegal in some jurisdictions. Always ensure that you have the right to access the content before trying to bypass security measures.
