PDF Viewer 3.0 has full support for image documents (a feature we introduced in v2.2 on iOS). This enables you to edit PNG and JPG documents as if they were PDFs; they can be annotated without converting them to PDF.

With PDF Viewer Pro, image support is brought to a whole new level. The editing data is stored directly inside the image file, making image documents first-class citizens for annotating, sharing, and collaborating, just like PDF documents are. 

And the best part: Image documents are fully compatible with all third-party image viewers, which will simply display them like any other image file.
