What are PDF streams?

Objects in a PDF file contain streams however, these are usually stored in binary format and often compressed. JPedal now has the ability to decode these PDF streams into plain text for you to view.

Get started

Using our PDF Inspector tool you can look at the internal structure and contents of any PDF file. If you open up the Cross-Reference Viewer or the Object Viewer you will see there is a new ‘Decode Stream’ button.

If you select a PDF stream object and hit this button a new window will popup with the decoded contents of the PDF stream. This will then allow you to view the commands inside a PDF file.

Here is an example of what this could look like:
