PDF Protector

Some documents must not reach the wrong hands - employment contracts with salary details, price quotes to clients still negotiating with competitors, medical files, tax reports, company financial documents. Sending such documents by email without protection is risky: the email could go to the wrong recipient by mistake, the recipient could forward the file, someone could see it on the recipient screen. Password protection ensures that even if the file accidentally falls into wrong hands - it will not open.

Another advantage is protection from changes. When a lawyer sends a draft contract for signing, they do not want the recipient to add clauses before signing. When an accountant sends an annual report, they do not want the client to change numbers. When a manager sends a price quote, they do not want the client to change terms. Permissions allow opening the file for viewing but block editing, printing, or text copying - full control over how the document is used.

In daily work of lawyers, accountants, financial advisors, HR people, and project managers - PDF password protection has become standard. Freelancers also send protected price quotes so the client cannot change before forwarding. Even private users protect personal documents before uploading to public cloud. The protection is thin - but in a world of data leaks and cyber attacks, it is significant.

Sending a rental contract to a new tenant and do not want them to edit the terms? Submitting a price quote and want only the password holder to open it? Sending a medical report and want it not to open if it accidentally falls into wrong hands? The tool adds a password to PDF with bank-grade encryption (AES-256), the highest standard available. Set a password, choose permissions (whether to allow printing, copying, and editing), and send without worries.

The process is simple: upload your PDF file, type a password (or click "Password generator" to create a strong password automatically), choose what actions are allowed for the recipient, and click "Protect PDF". Within seconds you get an encrypted file that cannot be opened without the password. The file looks and behaves exactly like before - except when trying to open it, the password you set is required.

There are two types of passwords you can set. Open password - required to see the content at all. Permissions password - controls what can be done after opening. You can set just one of them or both. The tool includes a real-time strength meter showing whether your chosen password is strong enough.
