Thanks to PDF Studio you can add to those PDFs your own notes, post-it notes, comments, audio commentaries, underline the important parts, make circles and other shapes, circle an important text, add hyperlinks, etc.
This way, these PDF documents will become a type of note that`s totally yours. But the PDF Studio functions go much further.

From PDF Studio you can also export/import JPG, TIFF or PNG images. In other words, PDF Studio contains everything you could wish for when working on and manipulating PDF documents.
