Convert is the graphics file format converter from the ImageMagick package.

Examples:

convert whatever.tif whatever.jpg

Converts the file whatever.tif to jpeg format and stores it as whatever.jpg.

convert *.jpg whatever.pdf

Converts the files *.jpg into a single PDF. However, this may yield large files while:

convert *.jpg -compress jpeg -quality 100 whatever.pdf

usually proves more satisfactory.
