PDF Password Protector – Add Password Protection to PDF Online
The PDF Password Protector is a browser-based tool for selecting a PDF document, entering a password, and preparing a downloadable copy. It displays the selected file name, page count, and file size before processing, helping users check their document details.
Important: This version does not apply genuine password encryption to PDF files. It creates a PDF copy, but the password entered in the tool is not used to encrypt the document. For confidential files, use a verified PDF encryption tool.

Why Protecting a PDF with a Password Is Important
PDF password encryption can help restrict unauthorized access to documents containing sensitive information. When properly implemented, it can be useful for protecting personal records, financial documents, business reports, and private work files.
A genuine PDF encryption tool applies encryption to the document itself. Simply entering a password into a form does not secure the file.
Who Can Use This Tool
The PDF Password Protector interface may be useful for students, teachers, office workers, business owners, and other users who need to select and process PDF documents in their browser.
Users who need to secure confidential information should choose a solution that supports actual PDF password encryption and verify that the resulting file requires a password to open.
Privacy and File Processing
The provided code processes the selected PDF in the browser using the PDF-lib JavaScript library. It does not send the selected document to a separate remote PDF-processing server. However, the library is loaded from an external CDN.
Because the current tool does not apply real encryption, the downloaded PDF should not be considered password-protected. Avoid relying on it to secure confidential documents.
