About Converting PPTX to ODP
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. When you need to move away from PPTX, the usual reason is simple: needs presentation software.
Converting your PPTX presentation to ODP solves that. ODP is the open presentation format of LibreOffice Impress. It is commonly converted to PPTX or PDF to share with PowerPoint users or for fixed-layout viewing. In practice you gain open iso standard and full presentation features. PrivConvert runs the whole PPTX-to-ODP conversion in server memory and deletes your file the instant the ODP is ready — nothing is stored, logged or reused.
When this conversion helps
- You need open ISO standard
- You need full presentation features
- You need no lock-in
- Sharing a PPTX presentation with someone whose software expects ODP
Tips for best results
- After converting, open the ODP 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 PPTX files at once; each is processed privately and deleted immediately.
How to Convert PPTX to ODP Online
Here is how a PPTX → ODP conversion works on PrivConvert, from start to finish. What you gain with ODP: open ISO standard.
Drag and drop your file into the upload area, click to browse your device, or paste a URL to a file hosted online. You can upload files up to 250 MB and batch convert up to 20 files at once.
Once uploaded, the conversion from PPTX to ODP starts automatically. The process runs entirely in an isolated environment - your data never leaves the secure pipeline.
Your converted file is ready instantly. Click the download button to save it to your device. The file is deleted from memory immediately after download.
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.
Your files are handled entirely by automated code. No staff, partner or AI model ever reads, stores or trains on your data.
Files are processed in volatile memory (RAM) and purged the instant your download is ready — nothing is ever written to disk, cached or backed up.
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.
