Download Morz Image Converter, to right click and convert your images
Dealing every day with images, regularly converting and resizing them, I needed these options as a context (right click) menu, to avoid opening a large editor, then the files in the editor, etc.
Morz Image Converter is a free utility offering such a system. It will let you right click on one or more images and convert them to the 14 most popular image formats, JPEG, JPEG 2000, GIFF, Adobe PSD, TIFF, BMP, PNG, ICO, PCX, TGA, PXM, WBMP, PostScript (PS), Adobe PDF.
It would be nice if MIC was offering also the option to save its settings, in case one uses always the same type of conversion (e.g. to jpg, at this degree of compression, etc).
You can combine this converter with Image Resizer, to have a quick and powerful right click convert-and-resize solution.
