5 Superb Free PDF Readers for Android


Portable Document Format (PDF) files had become the global standard for document exchange by the time the format became ISO standardized and was released as an open format in 2008. Soon PDF became a standard export function of software programs, and standalone readers soon appeared on the market. It did not take long for free mobile device PDF readers to appear.

The format was originally developed simply to encapsulate the layout of a document and included the fonts and graphics required to present it. Today, PDF files generally contain many more elements, including interactive elements allowing annotation, form-filling, video content and 3D objects and provide for encryption, attachments, and digital signature. There are many applications available now for viewing PDF files. The ones discussed here are five of the best free PDF readers to download and use on Android devices.
