ReaConverter is a convert all, really, tool for getting your image files from virtually any format to another. These include JPG, GIF, BMP, TIFF, PNG, PSD and they claim MORE than 400 other image or document types! These can then be converted to JPG, GIF, PNG, TIFF, JP2, PCX, TGA, PPM, BMP, PDF and 20 + other file formats... In short, pretty amazing! They seem well know for their Tiff to Jpeg conversions as a side note.

Not only can you batch convert images from one file format to another, you can also correct and manipulate quite a few things. Here are some of these:

Red eye remover wizard

RGB curves wizard

Settings for multipage images

Color transparency settings

Options to copy EXIF, IPTC and Alfa channel info

Built-in thumbnail creator

Customizable renaming tool, advanced output settings

You can download a demo version here. The cost of this Windows only tool (too bad for us Mac users) starts at 39 for the lite edition and goes up to 99 for the pro version. Seemingly not bad for what they claim this tool can do.
