2 - Adobe Acrobat Reader
The Adobe Acrobat Reader is another app you can explore if you are interested in a free PDF reader for iPhone and iPad. In free version mode, it supports reading the PDF on one page or scroll through mode and finding the content quickly with the searching text feature.
Similar to UPDF, you can take notes with annotating features like drawing, highlighting, sticky notes, etc.
However, if you want to use the editing, merging, creating, and converting features, you need to upgrade to the premium version at $9.9 per month, which is very expensive when compared with other tools.

3 - Apple Books
Apple Books is another free PDF reader for iPhone and iPad that you can try out. It's a little different from the Adobe Acrobat Reader app as it doesn't allow you to annotate PDF pages, but what it does do is let you highlight text, which proves very useful when you want to refer to certain information later. Using this PDF viewer, iOS users like you can enjoy its highlight feature, which is available along with the ability to bookmark pages that you want to keep track of.

The PDF viewer with highlighter also allows you to view bookmarks people have shared using this application, so if there are certain areas in a file that you would like to refer back to, simply share your page markers with them, and they'll be able to click on it and view the content instantly.
4 - Foxit PDF Editor
Foxit is another free PDF reader for iPhone and iPad that you can use to read files. We have found it very useful in most cases because of its ease of use, making it easy for beginners to adapt to the app quickly.
One feature we liked about this application is that you can also send documents via email once you've converted them into PDF format. This means if someone has sent a document for your review and clearing, all you need to do is add it to Foxit and then convert it into PDF format; the file will be automatically attached by Foxit when sent through an email.

This app is also straightforward to use and works speedily. In cases where you want to add a few pages to a file, it's also possible with this app. In addition, what we liked most about this app is that it lets you view PDF files in different modes such as single page, facing pages, and continuous, which makes the reading experience more engaging because of its flexibility.
5 - pdfFiller
The pdfFiller is another of our best PDF readers iOS users need to know of. You can use this app to edit and create PDF files on your iPhone or iPad.

Further, what we liked most about this application is its user-friendly interface, which makes it very easy for us to start using it straight away without needing to read instructions or tutorials. Once you've opened the app, the toolbars let you make basic edits like color, size, orientation, etc. However, if you're looking for more complicated features such as editing text, adding pictures, etc., then there are paid options available too.
