PDFelement-Powerful and Simple PDF Editor
Get started with the easiest way to manage PDFs with PDFelement!
Suppose you are a high school teacher and ask your students to submit their assignments via email. It would be easier to grade their papers digitally than to print every single task and use a pen. However, annotation might seem confusing, especially if you are a novice. You might not also get far if you have no idea which tools you should use to annotate your PDFs.
This article will introduce online and offline PDF editors, discuss their differences, pros, and cons and dive into four (4) tools you could use to add annotations to your PDFs.
In this article
Part 1. Annotate PDFs Online vs. Offline
PDF editors exist in both online and offline forms. While we can't explicitly say that one option is superior to the other, it is essential to understand your needs before you choose the best one. This section of the article will discuss the differences between offline and online tools to annotate PDFs and the pros and cons.
Here are some stark differences between online tools and offline tools:
User-friendliness: Online PDF tools are less user-friendly than offline tools because they are designed to be used through a web browser, which uses complex software. On the other hand, offline tools are easy to use because the developers created them for use with a mouse and keypad.
Features: Since offline tools are not limited by Internet connectivity, they tend to be more feature-rich than online PDF tools. Online tools would work best for you if you didn't need to use advanced features such as filling out forms or editing scanned documents.
Pricing: Lastly, offline tools are more expensive than online tools because you may purchase special software and licenses. However, they are a better choice if you need a PDF editor for professional use.
