Password-protecting a PDF can reduce the risk of casual unauthorized access when sending confidential material. This tool creates an encrypted PDF copy and asks for an open password before readers can view its pages.

These are a few practical situations where the tool may save time:

Small businesses sending private quotations
Offices sharing internal working documents
People protecting personal PDFs before transfer
Freelancers sending draft agreements to a named recipient

How to use Password Protect PDF

Select the PDF to protect.
Enter a strong password and repeat it for confirmation.
Choose Protect & Download.
Test the downloaded PDF with the password before deleting an unprotected copy.

Before you download: things worth checking

Keep the password somewhere safe; we cannot recover it.
Send the password through a different trusted communication channel.
Encryption may not be supported by every very old PDF reader.

Your input file remains on your device with the current browser-processing workflow. Save the result separately and check it yourself before uploading it to any official portal, printing it or sending it to someone else.
