Free PowerPoint editing and clean-up tools

These are the jobs that are tedious rather than hard — deleting every speaker note, unifying slide sizes, stripping macros before a deck leaves the company. Each tool does one of them across the whole file at once instead of slide by slide.

Nothing here re-renders your slides. The file you get back is the file you uploaded with one specific change applied, so fonts, animations and layouts you did not ask to touch come through unchanged.
