How To Lock Pdf File With Password For Free Without Acrobat

You can limit access to a PDF file by setting passwords and by restricting certain features, such as printing, editing, copying of texts, images and other content. There are many ways you can achieve this on Windows and Mac but in this post, I want to share with you how to password protect a pdf file without acrobat software on Windows PC.

Unlike Adobe Acrobat which will cost you money once your 30-day trial expires, you can opt for the free PrimoPDF software which also allows users to lock pdf files with password.

Once installed, PrimoPDF allows you to encrypt entire documents without any price tag. Additionally, it lets you set permission passcodes for tasks such as editing, copying, and printing.

Open the pdf file you want to lock, go to “File” > “Print

If installed successfully, you should see “PrimoPDF” in the list of printers. Select it and click “Print

Once the software opens, click on “Change” next to “PDF Security” as seen in screenshot below :
