FlashFloppy supports ADF and HFE images, among others, but these two are relevant for Amiga.
If an SCP or IPF image is of an AmigaDOS disk, then you can convert to ADF. Otherwise convert to HFE v3.
FF v3.25 is the latest version. You can check for the latest version at the following location, along with release notes for it:
