Impressive is a presentation software that provides the same presentation techniques that are known from PowerPoint with the difference that it can apply those to pdf documents and images. It offers links, overviews, page transition effects, highlights, spotlights and a sheet by sheet mode that can be controlled manually with the mouse buttons or automatically.

The portable software will extract a number of different files to the local computer system. Presentations can be started by dragging and dropping files onto the impressive.exe file in the program folder or by launching the tool from the command line. The basic command would be impressive file.pdf. More than a dozen command line parameters are available that can be used to control most aspects of the presentation software. Parameters exist to start the presentation in a custom resolution, a specific display ratio, to automatically flip pages after x seconds or to display a progress bar.

The primary application for this software is presentations. It can however be useful as a pdf reader as well especially for users who prefer to read page by page without scrolling.

There has not been any progress in development for the last six months which could mean that the project was temporarily or permanently halted. It does however work fine in its current stage but could use some usability additions like a graphical user interface to make things easier for the user.
