Why don’t we explore them in more detail?

Personal Use

Using PDF annotation for personal projects can be really helpful and fun. 

For example, you may want to work with your classmates to prepare a PDF presentation for school or university.

Additionally, you might want to share your comments on your colleagues’ resumes.

A PDF annotation software is of great use when it comes to effective collaboration.

Being able to comment on a specific sentence, word, or even letter of a PDF makes giving detailed feedback easier. 

Let’s have a closer look at using PDF annotations professionally.

Professional Use

Not just working, but also collaborating using PDFs is very popular among professionals across various industries.

Whether you’re in marketing, publishing, or education, you probably want to be able to create your content easily and flawlessly.

How can you do that using PDF annotation? 

Let’s dive into four use cases.

Use Case #1: Get feedback from your clients

Trying to reach your clients and sending countless emails used to be the main step of every review and approval process.

We’ve all been there. 

That’s where proofing tools come in handy.

Highlighting and commenting on PDF documents allow your clients to share their feedback quickly and effectively. 

Based on that, your colleagues are able to make any necessary alterations.

PDF annotation apps help you and your clients optimize feedback and approval processes and, of course, save  valuable time. 

Let’s get to the second use case.

Use Case #2: Get feedback from your teammates

When you’re working as part of a team, getting feedback from your teammates is crucial for professional growth.

Easy and convenient collaboration across team members is extremely important for every company.

By using annotation tools, teammates are able to share feedback on PDF files and improve task performance. 

This gets things done in a quick and efficient manner.

As simple as that!

Moving on.  

Use Case #3: Create educational content

Are you a company owner pursuing online growth through organic marketing strategies?

You’re going to need to start creating educational content.

Educational content is what attracts visitors to your site and that’s why it should be impeccable.

A PDF annotation tool allows you to improve your content by working on it with your colleagues in real-time.

Being able to underline text or add notes to your content can significantly improve sharing and collaboration procedures.

This way, teamwork becomes easier than ever. 

Let’s get to the last use case we have for you. 

Use Case #4: Create business and promotional materials

Your marketing material is a substantial expression of your brand’s identity

Business and promotional materials may vary from business cards and posters to brochures and product sheets.

The key success factor is to ensure the tone of voice is consistent across all business material.

Making sure you’re using the same, or similar, fonts, logo, colors, and images is very important for brand building.

PDF annotation tools support extensive checks and reviews, a feature that, if adopted properly among teammates, can lead to great results. 

All-in-all, it’s important to know your PDF annotation needs so that you can proceed to the second step of our guide. 

Let’s get into it.
