What is PDF annotation?

PDF annotation is adding suggestions in the form of comments or digital sticky notes to PDF documents in the proofing stage. 

Basically, PDF annotation refers to providing contextual feedback right inside deliverables in PDF format. Think eBooks, white papers, reports, etc. 

Here’s what it looks like when annotating PDF files with

You can click anywhere in the doc to leave comments where edits are needed. 

What’s more, your teammates can see your feedback in real-time at their end. This means your team’s email inboxes will no longer be harmed in the proofing process.

Annotation tools are the feedback superheroes we all need, making our lives easier with superpowers that include:

  • Document management super speed: makes document management faster and more efficient.
  • Magical feedback loop extermination: eliminates endless email exchanges from the proofing process.
  • Collaboration super-boost: streamlines communication among remote teams. 
  • Instant info transmission: facilitates real-time communication.
  • Feedback X-ray: enables visualizing information.
  • Online telepathy: facilitates asynchronous communication.
  • Proofing magnetism: helps keep all feedback in one place.

But before you can harness these benefits, you have to find an annotation tool that fits your unique needs. 

Following the five easy steps outlined below, you will find the perfect tool for your business.

Step #1: Specify your PDF annotation needs

PDF annotation needs exist! No, we didn’t invent them to make this process of finding the perfect PDF annotation tool more complicated.

When we say “PDF annotation needs,” we refer to pinpointing what you need an annotation tool for

Figuring this out is essential because it will increase the chances of finding the right annotation tool.

Ask yourself, “do I need something to help me with school or other personal projects? Or do I need it for work?”

Personal use

PDFs are part of our daily lives whether we like it or not. And it’s not only work that brings a PDF document to our desk to review.

Au contraire, school may present us with PDFs as well. 

If you’re a student, chances are you need to work with your classmates to prepare a PDF presentation or assignment. In this case, you might want to consider PDF annotation tools instead of exchanging opinions over email.

But that’s not the only instance when you’d use PDFs for personal projects.

Let’s say a friend or colleague asks for your opinion on their resume. Instead of explaining your points in a long text message, you could just use an online PDF annotator and add sticky notes with your feedback inside the doc.

The examples could go on forever. 

The point is that whenever you need to review a PDF, you can save time by using a PDF annotation tool that enables you to add text boxes and pin comments right on the sections you’re providing feedback for. 

Professional use

The most common use case for PDF annotation is, of course, business. 

For example, you need an annotator when you want to request feedback from your clients, teammates, stakeholders, etc.

What better way to do so than by simply sending over a link with your PDF where everyone can see your project and leave their comments with a simple click of a button?

This ability comes in handy, particularly when creating educational content and promotional materials. Think newsletters, user manuals, catalogs, brochures, and the like.

You can also use PDF annotators when you update your organization’s knowledge base and other old documents that need to be maintained. 

Jot down some of the most common instances when a PDF annotating solution would come in handy in your day-to-day. The resulting list will help you decide which annotator best suits your needs.

Additionally, ask yourself as many relevant questions as possible before jumping into solution comparison. Consider questions like:

  • Do I need to highlight text? 
  • Would I like to be able to use drawing tools when proofing? 
  • Are text annotations enough or do I need to attach files to comments? 
  • How often do I have to sign PDFs?
  • Do I need to edit the PDFs myself or am I just leaving comments for someone else to implement in their workflow?

When you know exactly what you need, you’re less likely to get bamboozled by nice-to-have features and can focus on the essentials.

Sure, you could also use Google Docs to send deliverables for review. But we all know what happens when someone leaves feedback in “Suggesting” mode, or worse, when they add an image to your doc.

The same goes for Microsoft Word documents: edits=doc parkour!
