Edit a Keynote deck in PowerPoint
When you receive a Keynote presentation but present in PowerPoint, you need it as .pptx first. This converter turns .key into an editable PowerPoint deck you can open and continue editing in PowerPoint, Google Slides or LibreOffice Impress — while your file stays private, processed entirely in memory inside a network-free sandbox and never stored.
About Converting Keynote to PowerPoint
Keynote is Apple's presentation software, saving decks as ZIP bundles of Apple XML. Its transitions and builds have no equivalent in PowerPoint, so converting a deck reliably preserves content and layout but not the animation. When you need to move away from Keynote, the usual reason is simple: not readable by powerpoint without conversion.
Converting your Keynote presentation to PPTX solves that. PPTX is the modern Microsoft PowerPoint format, a ZIP of XML that stores slides, animations, media and speaker notes. It is the standard for presentations. In practice you gain rich slides with media and animation and open xml standard. PrivConvert runs the whole Keynote-to-PPTX conversion in server memory and deletes your file the instant the PPTX is ready — nothing is stored, logged or reused.
When this conversion helps
- You need rich slides with media and animation
- You need open XML standard
- You need editable everywhere
- Escaping a proprietary Keynote file for the open PPTX standard
- Sharing a Keynote presentation with someone whose software expects PPTX
Tips for best results
- After converting, open the PPTX and skim the formatting — complex layouts occasionally need a small touch-up.
- Files up to 250 MB are supported, and you can batch-convert several Keynote files at once; each is processed privately and deleted immediately.

Private by design, not as an afterthought
Most online converters upload your files to a server, keep them for days, and may mine them for AI training or resale. PrivConvert was built the opposite way — around your privacy.
Every upload and download is protected with TLS 1.3, so your document cannot be intercepted on the way to the server or back to you.
Convert instantly with no sign-up, no email and no profiling cookies. We never build a profile around you or the files you convert.
Runs in any modern browser on Windows, macOS, Linux, Android and iOS — no install, plugin or desktop software needed.
Each job runs in an isolated in-memory sandbox, so most conversions finish in seconds instead of waiting in a queue.
