Fix PowerPoint to PDF Issues
PowerPoint exports usually fail in one of a few predictable ways. Below are the fixes for each scenario, in priority order.
Issue 1: Slides look blurry in the PDF
- Compress pictures at 220 dpi (HD), not 96 dpi.
- Avoid embedding screenshots scaled up — capture at slide resolution and place at 100 percent.
- Use vector shapes and SmartArt instead of pasted bitmap diagrams.
Issue 2: Fonts are wrong or missing
- File → Options → Save → Embed fonts in the file.
- Choose Embed all characters for full Unicode support.
- Stick with widely available fonts when sharing externally.
Issue 3: Animations and transitions are gone
PDF cannot represent animation. If your message depends on a build, split the animated slide into separate slides — one per build state. The PDF then shows each step as its own page.
Issue 4: Transparency renders as solid color
Some converters flatten PNG transparency. Use a converter that exports true PDF transparency layers, and avoid placing semi-transparent shapes over photos with similar colors.
Issue 5: Notes are not in the PDF
Choose Notes Pages as the publish layout in the export dialog. The default exports slides only.
Issue 6: Slide background gets cropped
- Confirm slide size matches the intended aspect ratio (16:9 or 4:3).
- Re-apply background from Design → Format Background instead of pasting an image.
Issue 7: PDF size is enormous
- Compress pictures globally (File → Compress Pictures).
- Replace embedded video with a thumbnail and a hyperlink.
- Remove unused slides and slide masters.
Issue 8: Hyperlinks are not clickable in the PDF
Insert links via Insert → Link, not as plain typed text. Clickable links survive the export as PDF annotations.
Issue 9: Slide numbers do not appear
Insert → Header & Footer → check Slide number → Apply to All. Then re-export.
Issue 10: Embedded fonts cause file bloat
If file size jumps after embedding fonts, switch from Embed all characters to Embed only characters used. The deck will be lighter while still rendering correctly for the characters you actually used.
