I'm wondering on how to mark in the pdf file and save it as a pdf.

For example page 2 of this pdf file, we have marking in blue. I need to know how it has been done.

This question came from our site for power users of web applications.

What OS do you use? – EntropyWins Sep 12 '12 at 13:45
Im currently using Ubuntu 12.04 – Learner Sep 13 '12 at 14:15

It depends on the software you use. Foxit reader allows you do that via "Comments -> Drawing.."

It has a bunch of other capabilites via the comments, quoting Foxit website:

A comment is a written note intended as an explanation, an illustration, or a statement of fact or opinion, especially a remark that expresses a personal reaction or attitude. You can type a text message or add a line, circle, or other shape to make comments on PDF files you are reading with Foxit Reader commenting tools. Most types of comments contain a pop-up window displaying your name; date and time you created the comments, and a text message. You can also edit, reply, delete, and move the comments with ease. This function is quite helpful to your studies and work if you have to make some notes on PDF documents. Foxit Reader has the following commenting tools; Annotation, Note Comments, Spell Checker, Text Markup, Text Select Tool, Drawing Markup, Typewriter Tool, Adding Text Box or Callout and viewing comments.

is there any linux equivalent of this software? – Learner Oct 21 '11 at 9:54
@Learner: Foxit is available for linux as well – MichaelS Oct 21 '11 at 10:10
It just installed Foxit reader 1.1 for Ubuntu, but there is no "Comments -> Drawing" menu or tool. – tsauerwein Apr 6 '13 at 17:27

Use adobe acrobat professional . By using that you can edit , note , highlight and even draw and save them

any free version for linux? – Learner Oct 21 '11 at 12:19
Acrobat professional cannot be used on linux (exception:Wine & that mess), and the hand annotation tools are crap-tastic. Trying to write on a pdf results in a sort of illegible scrawl that scarely I can understand. There are better options. – EntropyWins Sep 20 '12 at 15:26

On Ubuntu (any linux distro, for that matter) the best I can recommend is Xournal. Like a lot of OSS, your mileage and stability may vary, but you can always contribute to the code to make it right!

Check out this particular section in the manual for instructions on how to annotate a PDF.

I just checked and xournal is packaged for precise. So Yay! Easy install.

Now you can actually export annotations to PDFs in Okular (this was not possible until recently):

It seems Okular has to be built with Poppler at least version 0.20. It works with Ubuntu 13.04.

Since the question does not specify a specific platform to run the software, I'll suggest some iPad apps. The iPad seems to be the logical interface for this kind of handwritten annotation.

Here are some:
