Portable PDF-XChange Viewer 2.5 Build 201.0

As its name suggests, Portable PDF-XChange Viewer is an application that lets you view PDF files and which doesn't require installation.

In other words, your Windows registry entries are not changed in any way. Plus, you can store the tool on any external device and run it on any computer.

The user interface is familiar, so beginners will quickly learn how to work with PDF-XChange Viewer.

Once you have added a file (the "drag and drop" method is supported), you can view page thumbnails, switch to full screen mode, create and edit bookmarks, as well as flatten, summarize, import and export comments.

Furthermore, you can insert, extract  and delete PDF pages (i.e. PDF joiner and splitter), rotate or crop pages (e.g. remove white spaces), place a signature, attach a file, and recognize text on pages using OCR.

But you can also use various tools, such as hand, snapshot, select, zoom in and out, loupe, pan and zoom, stamp, sticky note, typewriter, text, highlight, callout, pencil, eraser, arrow, line, measuring and link tools.

In the "Preferences" menu, you can set the document layout (e.g. tabbed documents), document save method (e.g. full save or incremental save for digitally signed docs), allow multiple instances, configure rendering options (e.g. text smoothness) and performance settings (e.g. use system memory in percentage points), set units, grids and ruler options, and more.

The program uses a moderate amount of system resources and is easy to work with, whether you are experienced or not. However, we cannot access the help file and update checker (these options are not clickable in our case).

Also, if you use functions that have a "Pro" icon next to them, the output PDF file will have watermarks all over the pages. Otherwise, Portable PDF-XChange Viewer is a great tool for viewing PDF files and applying basic edit functions to them. We strongly suggest you try it.
