PDF-XChange Viewer offers tools for PDF editing and portability. The tool allows you to convert PDFs to other formats (JPG, PNG, etc.), as well as allowing you to add simple vector shapes such as arrows, rectangles or ellipses in addition to the usual editing features such as notes, underscoring and strikethrough. A document crowded with annotations can be read through the program’s semi-transparent coment boxes.
The software lets you fill in PDF forms, and in case you forget anything, the program displays all form fields in a clearly structured way with a navigation bar and coloured highlighting.
The export function, which saves a PDF as images, is particularly useful.
PDF-Xchange Viewer has a well-structured interface, which provides direct access to its various features. The tool supports shortcuts and provides a magnifier function. The rendering capabilities of the viewer are on par with those of Adobe Reader.
Note: The tool is also available in a mobile version available (download here).
