It’s important to remember that all of the “PDF Viewers” for desktop OS’ are also “PDF Editors”. I don’t see how web browsers are more secure since they’re connecte to the Internet?
How does Wireshark work? I’ve never tried it before?
From all of my research ONLY “PDF Viewer” for Android is unable to make changes to PDF files, but this is only available on Android…
I keep coming back to SumatraPDF as the best choice for Windows PC’s
I would strongly recommend against using a completely free PDF editor since the company has to find some way to make a profit, and you are most likely the product. Instead, take advantage of the Soda PDF free trial, which gives you unlimited access to its secure and safe PDF reader and editor. You can encrypt your files and add passwords to ensure that no one can open or view the files without your authorization."
