Part 2: FAQs for Free PDF Reader

Q1: What is the best PDF reader?

A: That's a tough question, but when taken in the context of cross-platform support, additional PDF capabilities, ease-of-use, and affordability, PDFelement (Win, Mac, iOS, and Android) and Wondershare Document Cloud stand out as the best PDF readers that you can use on any device or operating system. It is a versatile suite of tools that are user-friendly and intuitive.

Q2: What's the Best Replacement for Adobe Reader DC?

A: Many users who feel that Reader DC is bulky or lacks robust functionality have switched to the PDFelement ecosystem, where upgrades are affordable and free versions offer rich features and functions. In addition, the integration between desktop versions of PDFelement and the cloud storage service - Wondershare Document Cloud - enhances the collaborative experience while offering the best in desktop performance.

In Conclusion

It's important to know the difference between a simple PDF viewer and a proper PDF reader or editor. While the former allows you to look at the content, there's very little else you can do. On the other hand, a dedicated PDF reader gives you the navigation and UI tools you need in order to have a superior reading experience.

As an example, Google Chrome supports PDF viewing but there are no tools for annotation and so on; by contrast, a dedicated PDF reader such as PDFelement PDF Reader offers the full gamut of PDF reading tools that makes the experience pleasurable and highly engaging. In short, if you need a tool that can view PDFs as well as perform other advanced actions, then look for the best PDF reader, not viewer.
