As both the IGES 3D Exchange format (.igs, .iges) and ISO STEP product data format (.stp, .step) are fairly common and well support CAD formats used for exchange purposes, it should be easy to find a program that can convert one to another or vice versa.
Convert IGES 3D exchange format to ISO-10303 STEP product data.

Convert from igs file format
The tables with software actions are a good pointer for what a certain program does with various file types and often may give users a good hint how to perform certain file conversion, for example the above-mentioned igs to step. However, it is not perfect and sometimes can show results which are not really usable because of how certain programs work with files and the possible conversion is thus actually not possible at all.
