How to convert PPTX to PDF

PDF is the safest way to share a PPTX presentation: the recipient sees exactly your layout, fonts and page breaks, and nobody can accidentally edit it. This tool renders the PPTX with the LibreOffice engine, the same open-source office suite used by millions, and produces a standard, printable PDF with selectable text.

Step 1: Choose your PPTX file
Drag and drop a .pptx, .pptm, .ppsx file onto the converter or click to browse. It works on desktop, tablet and phone.
Step 2: Convert on a secure server
The PPTX is uploaded over HTTPS and rendered to PDF in an isolated temporary folder, usually in a few seconds.
Step 3: Download the PDF
Save the PDF file to your device. You can start again with another file right away.

Good to know

Each slide becomes one PDF page at its original aspect ratio (16:9 or 4:3).

Is it free?

Yes. Converting PPTX to PDF is free, with no watermark, signup or email required. Local conversions have no artificial file-size or daily cap; the practical limit is your device. This server-based conversion accepts files up to 25 MB.

Is my file uploaded?

This conversion needs a server engine, so the file is uploaded over an encrypted HTTPS connection, converted in an isolated temporary folder and deleted automatically as soon as the result is sent back. Nothing is kept, logged or shared.

About the formats

What is PPTX?

PPTX (PowerPoint Open XML) is the standard format for slide-based presentations, created and edited in Microsoft PowerPoint, Google Slides and LibreOffice Impress. A presentation is made up of slides that can hold text, images, charts, videos and speaker notes. Like other modern Office formats, PPTX files are ZIP containers storing XML.

Use PPTX whenever you build a slide deck to present, pitches, lessons, webinars and team updates. It keeps the structure of slides and notes intact, so you can also convert it to PDF to share a fixed version.

What is PDF?

PDF (Portable Document Format) reproduces a document exactly as it was laid out, regardless of the device, operating system or software used to view it. It is the standard choice for sharing, printing and archiving documents whose appearance must not change. Text-based PDFs can be converted to Markdown, plain text or HTML here.

Use PDF whenever the layout matters more than editing, reports, invoices, contracts, résumés and anything you need to share or print so it looks identical everywhere. Choose PDF when recipients should see exactly what you saw, with no fonts or margins shifting.
