Frequently Asked Questions (FAQ)

Does converting PowerPoint to PDF lose the animations?

Yes. PDF is a static format — it captures the final state of each slide without animations, transitions, or embedded video. Each slide exports as a single static image-like page. If animations are important, share the original .pptx file instead.

Why do my fonts look different in the PDF?

The font was not embedded, or it substituted during export. In PowerPoint on Windows: File → Options → Save → check “Embed fonts in the file” before saving as PDF. In LibreOffice: the Export as PDF dialog has a font embedding option.

How do I convert only specific slides to PDF?

In PowerPoint: File → Save As → PDF → Options → set the slide range. In Google Slides: File → Download → PDF exports all slides; to export a range, use File → Print → set the page range → Save as PDF.

Can I convert a PDF back to PowerPoint?

Yes — see how to convert a PDF to PowerPoint for free. The reverse conversion is imperfect but produces an editable .pptx.

How do I reduce the PDF file size after exporting from PowerPoint?

Use the Minimum Size option during export, or compress the resulting PDF — see how to make a PDF smaller for free. Ghostscript with -dPDFSETTINGS=/ebook is the most effective free option.

Does the free Google Slides method work for large presentations?

Yes, but very large files (100+ slides, many embedded images) may take longer to upload and convert. For presentations over 100 MB, the desktop PowerPoint or LibreOffice method is more reliable.
