We are able to remove password and restrictions from the PDF file. In many cases a password is not required, however if it is you need to know it. See this example).

We are able to rotate PDF files. See this (example).

Crop PDF

We are able to crop PDF files. See this (example).

Add Images

We are able to add images to PDF files. See this (example). This example uses the standard Golang image package which is slow for any serious work.

Add Images (using VIP backend)

We are able to add images to PDF files. See this (example). This example uses the bimg/VIP library as a backend to the ImageHandler interface UniDoc exposes. UniDoc is therefore flexible enough to allow implementors to use the image manipulation library of choice while defaulting to the one in Go. Hopefully the one is Go gets faster over time.
