Mac OS Automator pdf至jpg快速操作无效

Question

I produce pdf's from jpg's and vice versa all the time by right clicking on the file and using "Quick Actions" produced using Mac's Automator.

But while the workflow I use to produce pdf's works perfectly, the workflow to produce jpg's always gives me duplicate files. I've tried everything I can think of but I always get either no jpg produced or 2 of them. The illustrations below show each of my workflows, with comment bubbles on the presence or absence of the "Copy Finder Items" action which seems to be key.

Thanks.

Answer 1

I figured it out. When I removed the "Get Selected Finder Items" action I no longer got duplicate jpg's.

The process of posting a question helps me a lot. Maybe this will help others.
