PDF is the most popular file format, which means that you are probably in need of a great PDF reader to help you open the PDF files. There are lots of PDF readers that you can download through the internet. However, you may not be able to make the final decision among the numerous choices. Here in this post, I would like to recommend you with the best 7 PDF readers for iPad/iPhone.

I have several apps that generally open PDF files, including Adobe's PDF reader for iOS and several alternate browsers. I'm guessing it contains proprietary (Adobe) script on the forms that can't be handle in iOS as of yet. PS -There is no 'default app' setting on the iPad. Apple devices like iPhone and iPad never officially supported Adobe Flash. In 2010, Steve Jobs wrote an open letter called Thoughts on Flash (which still makes for a good read). In it, he outlined the reasons for not implementing Adobe Flash in Apple devices.

Notice: If you want to read some DRM-protected ebooks on any PDF reader you want, you must first remove the DRM from ebooks. In this occasion, the best ebook DRM Removal and ebook converter, Epubor Ultimate, can help you.
