Blaze ImgConvert

From Mystik Media:

Blaze ImgConvert is an advanced batch image/graphics conversion application that supports over 140 formats and an entire arsenal of options and features. Images can be resized or rotated automatically in the same process when converting. Comprehensive compression, sub-formats, various colorspaces, color depths, and much more are all options available. For files that already exist, options are provided to prompt for each existing file, automatically replace, skip the file, and rename (this option also supports naming templates as mentioned below). The software can also be configured to use the source file's folder for output, or use any pre-selected folder. Furthermore, Blaze ImgConvert fully supports conversion for multi-page files.
