Convert PPTX to PDF
To convert a PowerPoint to PDF, drop the .pptx into the converter above and click Convert to PDF; the finished PDF downloads when it is ready. Because office layout engines cannot run in a browser, the file is sent to our server over an encrypted connection, rendered by a LibreOffice engine, and then deleted. The result is a static PDF of your slides, one slide per page, that anyone can open without PowerPoint.
Encrypted upload on an EU server, deleted within about an hour.

Why convert PPTX to PDF?
A PowerPoint deck is an editable working file that needs PowerPoint or a compatible app to open and can be changed by accident. A PDF is the finished, fixed version: the recipient sees your slides exactly as laid out, on any device, with nothing to install, and cannot edit them. It is the format to send a deck for review, attach to an email, hand out as printed slides, or post for download.
What is PPTX?
PPTX is the PowerPoint format Microsoft introduced with Office 2007: a zip archive of XML slide definitions, media and layout parts. It is the lingua franca of slide decks, but opening one still requires PowerPoint, LibreOffice or a cloud office suite, and rendering differs between them. Converting a deck to PDF freezes the slides exactly as rendered, which is why so many decks are shared that way.
What is PDF?
PDF (Portable Document Format) is the 1993 Adobe format that froze documents into a fixed, device-independent layout, and it has since become the legal and professional standard for anything that must look the same everywhere: contracts, invoices, forms, papers. A PDF can contain vector text, images, fonts and annotations. Editing one is famously awkward, which is exactly the point; it is a final-form format.
Quality and what to expect
Each slide becomes one PDF page, and the slide text, layouts, tables and images come through faithfully. The honest limits, because a PDF is a document and not a slideshow: animations, slide transitions, embedded video or audio, and presenter notes do not carry into the PDF, and a font the server does not have is swapped for a close match. Standard business decks (titles, bullets, tables, charts as images) convert cleanly. On privacy, this is a server conversion: the upload is encrypted, the input is deleted immediately after conversion and the output PDF within about an hour, and the dropzone marks it a server conversion before you start.
PPTX to PDF FAQ
Do my animations and transitions carry over?
No. A PDF is a static document, not a slideshow, so animations, transitions and any embedded video or audio are not included. What you get is each slide as it looks at rest, one slide per page.
Can the person I send it to edit my slides?
No, and that is usually the point. The PDF is fixed, so a deck you send for review or as a handout cannot be changed by accident the way an editable .pptx can.
Will my presenter notes be in the PDF?
No. The conversion renders the slides themselves, not the notes pane. If you need the notes, export a notes-pages PDF from PowerPoint directly.
Is my presentation uploaded to a server?
Yes, this one has to be: rendering office documents cannot run in a browser. The .pptx uploads over an encrypted connection, converts, and is deleted: the input immediately after conversion, the PDF within about an hour. The dropzone labels it a server conversion before you start.
