📌Should I select desktop software or an online converter?

It is absolutely hard to say which one is better than the other one. Therefore, the decision is for you to make. Here is some specific information for your reference.

  • Desktop software: As it requires no internet access, it will help you with your request anywhere and anytime if you have your laptop. All the conversion and editing will take place on your PC and all the outcomes will be directly exported on it. Hence, your data privacy and information security will normally be guaranteed.
  • An Online Converter: It can be your primary option if you find it cumbersome to download and install a tool. Most online converters provide fast and instant conversion or editing services. However, an online converter can only work with internet access. Since all the conversion and editing processes are undertaken online, the converting or editing speed may be subject to instability. Also, limitations may apply to the free versions of some online converters, including task numbers per day, file size, file numbers, etc. Besides, the outcomes have to be downloaded in order to get them.

Conclusion

How to highlight in PDF has become an essential skill in the modern workplace or at school owing to the public’s frequent interaction with this file format. We sincerely hope that you can pinpoint an ideal solution after reading this article. However, it is strongly advisable to give WorkinTool PDF Converter a try.
