In this tutorial I will provide 2 steps how to do it.
- In first section I will guide you how to install it.
- The second section, I will show you how to convert your file.
A. Install Scan2PDF
I would like to show you how to install the program based on Ubuntugeek's website.
First, open terminal. You can find it in Aplication->Accessories->Terminal. Then, directly type: sudo vi /etc/apt/sources.list.
You may be requested to fill in a password, just type your password.
add this: deb http://gscan2pdf.sourceforge.net/download/debian binary
Then you need to update the source lists by typing: sudo apt-get update
After updating, now install the Gscan2PDF by typing this command: sudo apt-get install gscan2pdf
After installing the program, you can find the program in Application->Graphics->Gscan2Pdf

B. Convert Picture File into PDF
Now, its the time for convert your JPG or PNG File.
Just press import icon, or you can use shortcut Ctr+I, and choose your file. Next, you save it. Provide a name and put it in any folder you like. I myself prefer Desktop. Voila, now the picture without border in your PDF file.
