No matter what industry you are in, Adobe’s PDF is one of the widely adopted file formats when it comes to working with documents. It offers support for a wide range of elements, including everything from text to fonts to vector graphics to a few other essential information. Despite which, it still manages to keep files small, error-free, and usable, while also being safe to the extent that makes it difficult to modify without the right set of tools.

In the early days, the preferred option for editing PDFs used to be Adobe’s very own, Acrobat Acrobat Reader. However, over the years, a lot of apps and services have evolved, claiming to offer a much better set of features and support than Acrobat Reader. With a wide range of app options available on the App Store, it is difficult to find the ones that work well. So, to make things simpler, here are some of our picks for the best apps to read and edit PDFs on iPhone and iPad.
