Don’t most pdf viewers have an export to image option?
AVC to MP4
Do you actually have files with an .avc extension? AVC is a codec that can be used in many different container formats, including MP4. Where did these files come from?
OPUS to MP3
I actually agree that most audio conversion tools are needlessly awkward. Audacity will convert these just fine, though doesn’t really do bulk conversion. Foobar2000 will do it in bulk if you’re on windows.
