Why it's free
PDF and document tools traditionally mean uploading a file to some unknown server and hoping it gets deleted afterward. Wherever technically possible this runs entirely in your browser; anything that must touch a server processes the file for that one request and never stores or reads it for anything else. With the Watermark PDF, you get this without paying per generation or hitting a credit wall.
