Buyer's guide

How to choose a unlock pdf

When you have the PDF password, the main decision is whether you are comfortable uploading the file to a remote server or prefer to keep it on your own device. If you don't mind the upload, PDF24 offers the most features for free with only page-level ads, while PDF Candy emphasizes privacy with automatic deletion after two hours. If privacy is non-negotiable, PlumeDocs processes everything locally in your browser with no uploads, though it has fewer user reviews and less established track record.
