Hello. I frequently send project proposals, client contracts, and confidential reports in PDF format for my freelance marketing work. Lately, I'm concerned about files being altered, copied, or shared without permission. I want to learn effective ways to secure PDFs with encryption, passwords, and access restrictions. Any trustworthy resources or guides on this topic?
Hey. For comprehensive guidance on keeping PDFs safe, including strong password setup, encryption techniques, and controlling permissions, there's a very helpful site that covers these topics in detail. It also explains common ways PDFs can be exploited and provides practical advice for safeguarding sensitive documents in a business setting -the site is etcherpc.com (https://etcherpc.com/).
