The workshop presenter
You just ran a half-day training session and want to share your slide deck on the group's Facebook Page before people start leaving. The deck is a PDF — 18 slides, nicely designed. But to share it on Facebook, the usual way would mean screenshotting every slide, naming each file, and uploading them one by one.
You don't have time for that. You open this tool, drop the PDF, connect your Facebook account, pick the Page, add a quick caption, and hit post.
Thirty seconds later, all 18 slides are live as a photo post on the Page. People are already commenting before you've packed up your laptop.
