PPTX to PDF is on the release list
Each slide is rendered exactly as it appears in presentation mode and written to one page, usually in landscape. That needs a full document rendering engine, so it will run on our servers rather than in your browser. It is next in the queue and it will be free.
Do it now, on your device
No PPTX conversion runs on-device yet — but these do
We would rather point you at something that works than at a queue. These conversions run entirely inside your browser right now — no upload, no account, no watermark.
The details
What happens when you convert a presentation to PDF
PowerPoint's modern presentation format. A stack of slides, each one a page of shapes. Each slide is rendered exactly as it appears in presentation mode and written to one page, usually in landscape. The result is a the portable document format. fixed layout, universal, and the reason everyone can open the file you send them, produced on our conversion servers.
What survives
- The appearance of the slide, including fonts, images and animation positions
- The slide order
- Speaker notes, if the converter is asked to include them
What changes
- The animation, which is flattened into a single static state
- Any embedded video, which becomes a still frame or is dropped
- The ability to present — the result is a document, not a deck
Where it goes wrong
- Fonts that are missing on the converting machine are substituted and the slide reflows
- A slide with a video may show a black rectangle in the PDF
Why anyone would do this
A deck that only works in one program is a problem the moment you send it to somebody else.
About the format
PowerPoint's modern presentation format.
A ZIP archive of XML slide parts, one folder per slide, plus a master layout, theme, media and the relationships that connect them.
- Where it is good
- Holds slides, animations, charts, video and speaker notes
- Opens in PowerPoint, Keynote, Google Slides and LibreOffice
- The de facto language of presentations
- Where it falls short
- Fonts and animations render differently across platforms
- A big deck with video can be hundreds of megabytes
- Slide sizes and aspect ratios get converted, not preserved
- You will find it on
- PowerPoint, Keynote, Google Slides, LibreOffice Impress
The thing people miss
A 30-slide deck with embedded video is usually larger than the same video file, because the video is stored inside the archive.
About the target
The portable document format.
A tree of objects describing pages, fonts, images and scripts, with a cross-reference table and a file trailer. Text and vector graphics are stored separately from the page layout.
- Looks identical on every operating system and every device
- Holds text, images, vector art, forms, signatures and 3D
- Can be locked, compressed, tagged for accessibility and archived as PDF/A

Questions
PowerPoint to PDF questions
What actually happens to my PPTX file when I convert it to PDF?
Each slide is rendered exactly as it appears in presentation mode and written to one page, usually in landscape. So the PPTX file is unpacked, the content is laid out, and the result is written out as PDF. The appearance of the slide, including fonts, images and animation positions survives unchanged.
Will converting PPTX to PDF reduce the quality?
Partly. Some formatting is approximated because the two formats describe layout differently. The text itself is never re-typed, so no words are lost.
Is my PPTX file uploaded to a server?
This particular conversion needs a full document rendering engine, so it is processed on our servers. Your PPTX file is deleted automatically within an hour of the download being ready, and it is never opened or reviewed by a person.
Do I need an account or will there be a watermark?
Neither. There is no sign-up step, no email capture and no watermark on the output. The only limits are the ones your own device imposes.
What is the most common mistake people make when converting PPTX to PDF?
Fonts that are missing on the converting machine are substituted and the slide reflows
Why would somebody convert PPTX to PDF at all?
A deck that only works in one program is a problem the moment you send it to somebody else. In short: sending a deck that the other person can present
Something most people do not know about PPTX?
A 30-slide deck with embedded video is usually larger than the same video file, because the video is stored inside the archive.
Is this the same as converting PowerPoint to PDF?
A .pptx file is what Microsoft PowerPoint reads and saves, so PowerPoint to PDF is the same conversion as PPTX to PDF. Either way the conversion runs on our conversion servers, and there is no watermark on the result.
