FastStone Image Viewer is a free for home users as well as educational program for viewing , editing and management of images of many common formats .
It is valued for its ease of viewing and efficient performing of simple image editing functions. A comparable program (also) for Linux -based operating systems is XnViewMP .

Features and user interface

In full screen mode , the user interface uses the entire screen area and is not covered by menu bars. Only when you move the mouse pointer to one of the four screen edges do the corresponding menus appear, which offer editing and organizational functions.

The main window of the program contains a file browser which can be used to select the folders with digital images on the data carrier. After opening a folder, the program creates a view with thumbnails, which are saved in an internal database and thus accelerate the next access to this folder.

In addition to the most common image formats JPG , BMP , GIF , PNG , TIFF , PCX , TGA , JPEG2000, PSD, WMF, CUR and ICO, FastStone Image Viewer also supports RAW and special formats from various manufacturers such as Canon , Nikon , Olympus , Fuji , Adobe , Minolta , Pentax , Panasonic and Sony .

However, it does not yet support Unicode .

When saving images in a lossy file format (e.g. JPG), the influence of the degree of compression on the image quality can be checked.

A click on one of the miniature views shows an enlarged image, with a double click the full screen and thus the editing screen is opened at the same time.

The program knows the usual Windows key combinations as well as many additional function keys for fast operation and can be conveniently operated via context menus and the fold-out side menus mentioned above.

Development and version history

Since version 2.50, it is also possible to insert text, free-hand drawing, drawing geometric elements and inserting watermarks , and images can be marked for batch processing .

The images can be deleted, moved, copied, converted, renamed and converted in batch mode. Images can also be printed, watermarked or two to four images compared with each other in an enlarged view. The program also supports TWAIN compatible scanners and thus allows the direct insertion and processing of scanned images.

Exif information can be called up from any view, including any GPS data. There it is also possible to insert comments in JPEG files.

External image processing programs can be started from the program, which enable further processing.

The images in a folder can be played in a slide show with a wide range of configuration options, optionally with background music.

For a short time, version 2.70 of the Image Viewer was available as a standard and a paid “Pro” version. Since version 2.8 there is only one version of the FastStone Image Viewer that is free for private use.

With version 3.0 the viewer became Vista compatible. Further innovations are the possibilities for saving PDF files (also multi-page) and for generating multi-page TIFF files. Furthermore, images can now be cropped in batch mode and renamed according to the Exif data (date, time).

Since version 3.1 there is a multilingual version in Danish, Dutch, French, German, Hungarian, Italian, Norwegian, Polish and Spanish in addition to the English version.

With version 3.3 further image processing functions such as brightness, contrast , gamma correction , saturation , sharpening and similar have been added. In addition, the slide show function has been expanded and a download function from the memory card has been integrated.

Version 3.4, released in November 2007, added improvements to the user interface, improved color matching functions and introduced batch processing for RAW files.
