BatchBlitz is a batch image processor with an included photo edit program. It allows you to add a watermarks, filter source files, rename/convert images, resize/rotate, automatically apply color corrections and more. An instant preview gives you a look at effects before executing. Additionally, the program supports regular expressions for filtering files to be processed and for the renaming of files. A wizard can categorize files based on metadata (EXIF or IPTC tags).

While the editor program (SunlitGreen Photo Editor) is separate from the batch program, it's included in the application folder or can be launched from within BatchBlitz.

FastStone Photo Resizer is a batch image converter/resizer that enables users to convert, rename, resize, crop, rotate, change color depth, add text and watermarks to many images at one go. Supports file renaming and a conversion preview is available before processing.

Any set of conversion settings can be saved for future use.

RIOT (Radical Image Optimization Tool) presents a before-and-after image compression view that allows you to reduce file size of an image into JPG, PNG, or GIF format. Includes optional metadata removal, batch operations, compression to a target file size, transparency options, and other common editing functions (flip, rotate, zoom, pan). Notable versus similar software in the ability to gradually reduce the available colors one-by-one (7, 8, 9, 10...), not just milestones of 16, 32, 64 etc.

The program is also available as a plugin for XnView, GIMP, or Irfanview (see website).

Functional in Linux using Wine. Many of the official entries here on PortableFreeware have used RIOT for compression. Note that the installer version of this program is considered adware.
