PDF Key vs Big Timer

PDF Key is a simple app for adding an open password to PDF files. Choose a PDF, enter a new password, and save it as a password-protected PDF. If the selected PDF is already password-protected, you can unlock it with the current password first. Leave the new password blank to export a PDF without a password. PDF Key does not include editing, merging, splitting, OCR, scanning, cloud sync, or password recovery features. It is focused on one job: protecting PDFs with a password. Features: ・Add an open password to PDFs ・Open password-protected PDFs ・Export without a password by leaving the new password blank ・Save as a new file without overwriting the original ・On-device processing ・No account
