Remove password protection from a PDF using our free online app or learn how it works with our embedded iText 7 Sandbox.


Use the free online PDF Unlocker app

Click the box below to upload a PDF, or drag and drop a PDF into the box.

You will then be asked to enter the Owner Password for the PDF.

Click Unlock PDF and then download the resulting PDF.

Or play in the iText 7 Sandbox

In this Sandbox you can see how the the unlocking code works in iText 7, and experiment with changing the code yourself.

Click Upload File and make sure the file name of the PDF you upload matches the name you specify in private static final String ORIG and that the PDF is password protected. Then enter the password in private static final byte[] OWNERPASS.

Then click Execute to run your code. To remove an uploaded file, click the x displayed next to the file name.

You can click the switch at the top of the Sandbox to change between the embedded Java and C# compiler.
