Protect PDF

Use the free Protect PDF to add a password and encryption to lock a PDF.

That is the whole scope of the page. It sits in PDF Tools, the group for merge, split & convert pdfs. The Protect PDF only does the job in that first sentence.

Protect PDF runs in your browser. The file or the figures stay on your device, and the free plan does not ask you to create an account.

Use it when you already have the PDF, or the pages, and you need the file changed in the way the description says.

Open it when you need to add a password and encryption to lock a PDF. If you need a different output, pick the tool whose description names that output.

Upload the file and set the page order or the range before you run it.

Run it once with the values you have. The result should line up with this promise: Add a password and encryption to lock a PDF. Change one field if you want a second case, and keep the other fields the same so you can see what moved.

Open the download and check the pages you cared about: order, rotation, and whether the text is still selectable.

Keep the units, the dates, and the file type that the form showed. A number from the Protect PDF is ready to copy only after you have checked it against the labels on this page.

A scan stays a picture unless the tool says it reads text. Compression can make images inside the PDF softer.

Anything the description does not mention is outside this tool. Use the result as the estimate or the file this page promised, then check the source that actually applies to your bank, school, client, or project.

Other tools in PDF Tools include Rotate PDF, Delete PDF Pages, PNG to PDF, PDF to PNG, Image to PDF and BMP to PDF. Open the one whose description matches the next job.
