At first glance, PDF seems impossible to change. But don’t panic! By the end of this article, you will have a pool of options on how to markup a PDF.

When PDF was first introduced to the market by Adobe, it seemed to be the solution, as it was the first format to combine visual and text elements on one page. Truly, it was the answer to the prayers of all those who worked in any sort of design area at that time. Now, however, PDF does not seem to be beyond anyone’s expectations.

Today everyone uses PDFs at work daily. No matter what your line of work is, you are likely to open a lot of PDFs per day. And the possibility of marking up a PDF whenever you need to apply quick edits would accelerate the frustrating revision process significantly.

That’s where PDF annotation software comes in.

A PDF annotation tool allows you to write on PDF documents, both on media and text content. It helps to avoid any hustle or confusion of endless revision requests.
