PDF or Portable File Document is an extensively used file format in offices and online education systems.

PDF files are quite easy to share through emails and present content in an easy-to-read manner. These also help in preserving the content’s structure throughout various devices. No matter what device you are using, a reader will be able to see the same layout.

Another important feature of PDF files due to which these are highly popular is their security. PDF files come with an encryption feature, enabling you to password-protect your file. This way, only the allowed person can view the file; thus, your file content remains safe and secure.

Besides the convenience that PDFs offer, they also have one limitation: their non-editable nature. It is possible to copy and print the content of a PDF file, but one cannot edit it. It is a compliment to its security aspect; however, sometimes, you may need to update the file. You may need to add notes to it for reference, and for that, you need the capability to write on it.

Fortunately, there are several ways available that enable you to write on a PDF file. Let’s explore some of the methods using which you can write on a PDF file and update it easily.
