Buyer's guide

How to choose a sign pdf

When picking a PDF signing tool, first decide whether you need a legally binding digital certificate or just a visible mark for your own records. If legal enforceability and privacy are priorities, choose a tool that offers certificate-based signing and deletes your file afterward. If you only need to add a quick signature and don't mind creating an account, a simpler free service will work. The key differences here are that PDF24 provides certificate support and automatic file deletion for privacy, while PDF Candy focuses on ease of use but requires sign-in and offers no privacy guarantees.
