Frequently asked questions about Protecting PDFs

How do I add a password to my PDF?

First, upload the PDF document you wish to protect. Then, in the designated fields, type your desired password and confirm it by typing it again. Finally, click the "Protect PDF" button. Your encrypted PDF will be downloaded immediately.

Is it safe to protect my PDF with PDFClear?

Yes, absolutely. PDFClear operates entirely client-side, meaning your PDF document never leaves your browser and is never uploaded to our servers during the protection process. This ensures maximum privacy and security for your sensitive information.

What kind of encryption does this tool use?

Our tool utilizes robust standard PDF encryption methods (typically AES-256 bit encryption where supported by the underlying libraries) to secure your document. This level of encryption is widely accepted and provides strong protection against unauthorized access.

Can I remove the password later?

Yes, if you remember the password you set, you can easily remove it using our dedicated "Unlock PDF" tool. Simply upload the protected file, enter the correct password, and download the unlocked version.
