PDF is short for Portable Document Format and it is a versatile file format for sharing documents online. For example, many contracts and documents are signed virtually and saved as PDFs because the format tends to be more secure.

PDF files have been around for over two decades now. There isn't a single user who has not gone through these as they are ubiquitous. PDF files not only contain text, but they also have media such as audio and videos.

If you're exchanging and creating PDFs with your peers or coworkers, chances are high you'll need do some notation. Annotating PDFs refers to adding notes and important remarks to the PDF for other readers. It's common during the development process, and may be required for you to sign or fill out a PDF as well.

Don't worry if you don't have much experience annotating like this on a computer. We'll go over the easiest ways to annotate a PDF on Windows and Mac OS.

What Is an Annotation?

When you mark up text, you are in fact having a conversation with what you are reading. So, an annotation is important.

Annotation is a fancy word for "marking a sentence, paragraph, page or anything else." There are various markup tools you can use to annotate what you are reading: underline a sentence, use a highlighter, add a comment with an arrow, flag with a symbol, draw a shape around it, tag a Post-It note on it, etc.

Use the selection and the markup tools annotate the PDF. You can use type, sketch, draw, use shapes, add notes, sign, and change the format for all.

7 Best PDF Annotator Software for Mac and Windows Users

Creating or reading a PDF is simple enough, but if you want to edit or annotate a PDF without changing it to a different format (or disturbing its layout), you'll need to have a dedicated PDF editor on hand.

Conventional PDF readers don't make it easy to draw or write freehand onto documents.

PDF editors are a different beast than PDF readers or word processors. They're designed to handle one specific format and perform a limited number of tasks within that format.

The ability to allow single or collaborative annotation and markup is paramount. Good PDF editors should offer helpful annotation tools like highlighting, sticky notes, comment boxes, message stamps (like “approved” or “confidential”), or even freehand notes.

Many – including Adobe's own Acrobat Reader – make it easy to highlight text or add your signature.

1. Adobe Acrobat Reader DC

If there's something you need to do to a PDF (and if you want to look right and stay secure), Adobe Acrobat is your best choice.

This is the industry standard for PDFs. Adobe makes it easy to create, edit, and sign PDFs (and track their activity) with its modern, intuitive interface.

The software is available for Windows and macOS systems, as iOS and Android apps, and as a Google Drive add-on.

2. Foxit Reader

Foxit PDF Reader allows you to annotate otherwise unmodifiable PDF files using its suite of drawing tools.

These drawing tools feature a variety of shapes, such as arrows, lines, rectangles, ovals, polygons and clouds, but it also offers a freehand Pencil Tool that allows you to draw or write whatever you desire.

If you mess up, don't worry; Foxit PDF Reader also offers a Rubber Tool which allows you to erase marks made by the Pencil tool.

3. Drawboard

Drawboard PDF is now available for free through the Microsoft Store. Drawboard PDF can open, read, mark up, edit, write, annotate, ink, draw and save multiple large and complex PDF documents.

Best tablets with a stylus pen for annotating, Writing and Signing PDFs

If you're going to mark up a PDF, you'll want a good stylus that come with a tablet. These styli will help you create a clean signature and attractive annotations.

This is just comes down to what features you want and how much you're willing to pay. Do you need a full OS? Or just something basic that can open PDFs and ink on them.

If marking up PDFs is something that you do a great deal of and a key part of your job, I would recommend getting the portable touch screen device ( such as ipad pro, surface pro, samsung galaxy tab.... ) you can find that supports the use of a highly-sensitive pen stylus.

Just open your document in PDF Reader, and you can begin writing on it with your favorite stylus or use a finger on a touch device.

If you already have a separate mac or pc and don't need portability I'd recommend a cheaper option - USB drawing tablet.

All graphics tablets, with or without a display, support to write, sign name, comment, highlight on PDF like using a real pen on real paper.

The big time saver is the programmable buttons and dial that allow instant access to any menu feature you frequently use. It's a huge time saver.

Digital pens are also a step above. it can be used as a mouse as well as a drawing tool. Angle and pressure sensitive as well as two programmable buttons on the pen (I use for single and double click selections).

The drawing board senses pressure so it is recommended to use the least amount of pressure from your hand while writing.

They can be a little unnatural to use at first, hopefully you'll get used to it. They start cheap enough that you can see if you like them anyway.

One tip - whilst an A4 or larger surface feels like it ought to be a good idea, you end up moving your pen quite a lot and it gets tiring. Try smaller first.
