When to use which
-
You only have the PDF of a deck and need to change it.
Use PDF to PPTX, fix the text, then save or present from PowerPoint.
-
You need to send a deck that looks the same on any device.
Use PPTX to PDF. Fonts, layout and charts are fixed in place.
-
The deck works but looks dated.
Convert it if needed, then click “Redesign in Wonderslide” on the result screen. Wonderslide keeps your text and applies one consistent design to every slide.
What these converters don’t do
- They don’t turn images and charts from a PDF into editable objects.
- They don’t recognise text on scanned pages (no OCR).
- They don’t open password-protected files or old .ppt files. Save as .pptx first.
- A PDF can’t hold animations, transitions or video, so those don’t carry over.
