How to make annotations on a PDF file

Last updated on August 6, 2018 by

Annotation is a comment or note added on an existing document like a PDF file. PDF files are common files that can be found online, as well as on e-mail attachments as they are small in size. There are several reasons why people make annotations in PDF. Some people like students and teachers who are reading a book or material in PDF may annotate to easily remember important terms or to quickly go back to a specific part for future reference. This can also be done when proofreading articles or content. The annotated file will then be sent to the person who wrote it to make necessary revisions.

Ways to Annotate PDF Documents

There are various applications that you can use for annotating on PDF files. They offer different features so it’s best to learn more about them to weigh your options and select which one is the best tool for you.

PDFescape

This is an online and free program that you can use to annotate a PDF file. If you do not want the hassle of downloading and installing a program, then this one is a good choice. It supports popular browsers including Internet Explorer, Mozilla Firefox, Chrome, Safari and Opera. It’s easy to use though it only offers two options for annotations and they are sticky notes and highlight. Sticky notes let you write some notes if you need to, while highlight, as the term suggests, would highlight the specific part you wish to be highlighted. If you want to try this program, go to its home page and click Edit Your PDF Now. Upload or load your PDF document and start annotating by clicking on the Annotate tab.

This is web based so it does not require any download or installation and it also does not cost anything. However, it does not support loading of PDF files online; just the ones saved on your computer. Click Upload Document and select the PDF file you wish to annotate. You can add comments or texts on the file, as well as draw, highlight and strikeout texts.
