Free Mac app: fixes PowerPoint images that look sharp on Mac but pixelated on Windows

If you paste figures or tables from PDFs into PowerPoint for Mac, they may look pixelated when the deck is shown on a Windows PC (conference rooms, classrooms). This has been reported for years without a fix.

Cause: PowerPoint for Mac stores the pasted PDF plus a small low-res backup image. Windows can't read the PDF, so it shows the backup.

I made a small, free, open-source menu bar app that uses the sharp PDF already in the file to create a Windows-safe copy (name_windows.pptx). Your original is never changed. Drop files on the icon, or let it watch a folder so it happens automatically.
