Part 2: Limitations on Online PDF Annotators
Online Annotation tools can be fun and easy but still require more attention because they need that extra struggle to use them. Internet connectivity is the main requirement to run an online annotation tool for PDF, but in case you have no access to the internet, then what? Then you suffer, and the internet connectivity issues become a root cause of other limitations as well.
If you don't have a strong internet connection, you would probably suffer from uploading a large-size file because, generally, this requires a fast connection. Also, when talking about file size, many web-based annotators don't support a large-size file, and a person may have to jump from one tool to another to upload and edit. Many web-based annotators don't provide a secure platform to the user, so people like to switch to offline tools as they are safer and need no internet connection.
Part 3: An Offline Alternative to Online PDF Annotator- UPDF Annotator
An all-in-one solution to your annotation problems is UPDF- free PDF editor. People who don’t like to use online annotation tools because of the limitations and formalities they have to tend to move towards offline tools. One exceptional offline tool is UPDF because it has all the features a person would need. The annotation tools offered by UPDF are highlighter, shapes, drawing tool, strikethrough tool, sticky notes, text box, stamps, etc.
But with that, it also has PDF editing tools. It is a free PDF commenting tool which works seamlessly; you can easily cut and delete the text, but when required, it also helps in adding new text. When you add new text, you can simply change the font style and size of the text. Even if you use a pencil tool, you can increase and decrease the thickness of the text. But with all that goodness, it also has a flaw in it that it doesn't have a web-based version. So, if you are a Windows or Mac user, we recommend you shift to UPDF.
Annotation is a necessity for a person who has all the file work. Since the world is changing rapidly and things are more digital now, PDF files need an efficient editing solution as well. For that purpose, we have listed 6 different types of PDF commenting tools.
One of them is an offline alternative to the rest of the 5 online tools. The user can use any of the online tools mentioned above, but people usually prefer offline annotation tools because of their versatility. UPDF is our recommendation to all the Mac users out there.
