PPTX to PPT is on the release list
The deck is opened and re-saved in the target format, mapping each slide and its layouts onto the target's own structure. 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 between presentation formats
PowerPoint's modern presentation format. A stack of slides, each one a page of shapes. The deck is opened and re-saved in the target format, mapping each slide and its layouts onto the target's own structure. The result is a the original binary powerpoint, from before 2007, produced on our conversion servers.
What survives
- The slides, their order and their content
- Images, text, charts and the master layout
What changes
- Animations and transitions that the target format does not support
- Some SmartArt graphics, which become ordinary images
Where it goes wrong
- A different slide aspect ratio will letterbox or crop the content
- Video links often break, because the target format handles media differently
Why anyone would do this
A deck built on one platform usually has to be shown on another.
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 original binary PowerPoint, from before 2007.
A binary compound file holding a record stream of slides, each with its own shapes, text and formatting.
- Opens in every version of PowerPoint ever shipped
- The only format some very old presentation tools can read
- Occasionally the only way to recover a badly damaged deck

Questions
PPTX conversion questions
What actually happens to my PPTX file when I convert it to PPT?
The deck is opened and re-saved in the target format, mapping each slide and its layouts onto the target's own structure. So the PPTX file is unpacked, the content is laid out, and the result is written out as PPT. The slides, their order and their content survives unchanged.
Will converting PPTX to PPT 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 PPT?
A different slide aspect ratio will letterbox or crop the content
Why would somebody convert PPTX to PPT at all?
A deck built on one platform usually has to be shown on another. 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.
