Convert PPT to PPTX
PPT is the older binary format used by presentation software before 2007, and PPTX is the current XML-based format most software expects now. To convert PPT to PPTX, open the file in a converter and export it as PPTX. Doing it on your own computer keeps the slides, and any author or company details saved inside, off other people's servers.
All 2,748 conversions verified on macOS, Windows, and Linux against the shipping release, this one included. Every conversion runs entirely on your own computer.

PPT vs PPTX: what actually changes
| PPT | PPTX | |
|---|---|---|
| Opens everywhere | Yes, but newer presentation software opens it in compatibility mode | Yes, opens directly in current presentation software |
| File size | Larger, less efficient binary format | Smaller, compressed XML container |
| Quality | Lossless | Lossless, slides and formatting carry over as-is |
| Newer features (advanced diagrams, some transitions) | Not supported | Supported |
| Keeps author, company, and comments (metadata) | Yes | Yes, unless you remove it |
When to convert, and when not to
Convert PPT to PPTX when you want to edit an old presentation in current presentation software without the compatibility-mode banner, use newer formatting features, or just want a smaller file to send.
Keep the PPT original if it needs to open on an old machine still running an old version of presentation software from before 2007, since that software can't read PPTX.
Why not just use an online converter?
PPT and PPTX files often carry more than the slides you see. Author names, company names, and edit history can be stored inside the file. When you convert through an online tool, that document and its hidden details land on a stranger's server. Converting on your own computer means the presentation never leaves your machine.
Questions
Does converting PPT to PPTX lose any slides or formatting?
No. It's a lossless conversion, the slides, text, images, and layout carry over as they are.
Will speaker notes and comments carry over?
Yes, speaker notes and comments in the PPT file are kept in the PPTX.
Can older versions of presentation software open a PPTX file?
Presentation software from 2007 and later opens PPTX natively. Versions before that can't open it without a separate compatibility pack.
Does the PPTX keep the author and company metadata from the PPT?
Yes, that information carries over unless you clear it yourself, which is worth doing before sharing a file outside your organization.
Can I convert PPT to PPTX without uploading the file anywhere?
Yes. A desktop app like Morphjet converts it on your own computer, so the presentation never travels over the internet.
