For copy and edit restrictions, PDF Champ PDF Encryption Tool gave a really smooth experience. The file was protected with password security and strong AES encryption, and separate options were available to block editing, copying, printing, and comments. This was especially helpful for office reports and study material where the original content needed to stay unchanged. Even after applying all restrictions, the file quality stayed exactly the same. Fonts, images, and layout were not affected at all. Another useful part was that multiple files could be secured together, which saved time during work. It felt simple to use and worked well for secure PDF sharing. Visit here: https://www.pdfchamp.com/pdf-encryption/
