PhotoBatch is freeware. It is completely free and contains no adware, spyware, or other malware embedded.

PhotoBatch does batch processing, format conversion and renaming of image files. Scripts of commands including input and output setup can be saved and loaded for reuse. A batch script may be run on a single image, on a folder, or on a list of files and folders. Script commands may be tested and run on a sample image. Includes 91 commands and supports 10 image file formats (jpg, gif, bmp, png, tif, pcx, tga, wmf, emf, psp) plus various camera raw formats (Canon, Nikon, Kodak, FUJI, Olympus, Pentax, Sony etc.).

A PhotoBatch sample screen shot:

Batch processing, file format conversion and renaming of image files.
Scripts of commands can be saved and loaded for reuse. Input and output setup may be saved with the script or set at runtime. Batch script may be run on a single image, from a folder, or from a list of files and folders. Script commands may be tested on a sample image. Includes 68 imaging commands and 23 I/O or execution commands. Supports 10 image file formats (JPG,BMP,GIF,TIF,TGA,PNG,PCX,WMF,EMF,PSD).

This is designed to be an intuitive and easy to use single image and batch processing application. All but the simplest commands provide a dialog window where you can observe, on a sample image, the effect of the command and see the effect of changing parameters. Just move a command into the script list box.
Most all commands may be set using absolute pixel values or relative values (%). Setup the script commands using relative values and you may apply the script to any size input image and get the output desired.
Input files may be filtered in various ways (file type, date, size, aspect ratio). A single script may produce multiple output images from each input image. Output files may be saved in a different file format and renamed in various ways (prefix,suffix,auto-number) This is designed to operate on and output 24 bit single image files. It does not support mult-frame image input or output (AVI or multi-frame gif). Within this constraint, it is simple to use and powerful. Each command by itself is simple in its effect, but a sequence of commands can make a script that does complex effects.

Includes the following 91 script commands:
