Does each slide become one page?

Yes, at the deck's own slide dimensions — a 16:9 deck produces 16:9 pages rather than being letterboxed onto A4.

Do I need PowerPoint?

No. The conversion is done by BizTray's own document engine, with no Office licence involved.

What happens to embedded video?

A PDF page is static, so video cannot carry over. The slide renders with its poster frame in place.

Can I convert dozens of decks in one run?

Yes. Drop the folder in and convert the lot — there is no daily quota, because nothing is being processed on someone else's server.

Why convert

Why convert PPTX to PDF?

Sharing the PPTX gives the recipient an editable copy that renders differently depending on their fonts and their version of PowerPoint. A PDF gives them exactly what you designed, opens anywhere, and is a great deal smaller to email.

A lecture or conference deck has to be handed in or circulated as a PDF.
You want to distribute slides for reading without handing over an editable source file.
The deck is full of custom fonts and you need it to look the same on a machine that lacks them.
You are archiving a term's worth of presentations in a format that will still open later.
