I recently started freelancing and need to email a 10-page PDF contract with sensitive banking details to a new client. I want to password-protect the file on my Mac so only they can open it, and also block anyone from editing the text. What is the easiest way to set this up without paying for an expensive subscription?
Honestly, just use Preview on your Mac since its already built in. Open the file, go to File > Export, and check the Encrypt box to set a password. I use it for vendor contracts all the time and never needed paid software.
