Is there any possibility to block the copying option of a PDF file?

Question: I had written a word document and converted it to PDF file, I don't want the one who opens it could edit it freely, that means, they can just read it, how to do this ? Is there any possibility to block the copying option while I am converting from word document to PDF?

Solution: You need Infix PDF Editor. Just 3 steps, you can add password and permissions to protect PDF document.

3 steps to add password and permissions to block the copying option of a PDF file with Infix PDF Editor:
(1) Open source PDF file -> Click menu "Document -> Security...".

(2) Set PDF document security properties in "Document Security" dialog.
(2-1) Set "Security Level". Here, we select "128-bit AES".

(2-2) Set "User Password" required for open PDF document, "Owner Password" required to change PDF security and "Permissions". Here, we don't want others to copy and edit the PDF document, so we set "Editing" and "Copying / Extracting Content" permissions unchecked.

(3) After verifying the new PDF password ("User Password" and "Owner Password"), the specified password and permissions will be applied to source PDF file successful.
