Are my files uploaded to a server?

No. Zero files are transmitted anywhere. Xonvert processes everything using client-side JavaScript and WebAssembly. Your files stay on your machine.

Can I preview the ODF output before downloading?

Yes. Xonvert shows a preview of your converted file so you can verify the result before saving it to your device.

Can I convert password-protected PPTX files?

Encrypted or DRM-protected files cannot be converted. You'll need to remove protection first using the original software.

Can I convert multiple PPTX files at once?

Yes! Drag multiple files into the converter for batch processing. All files convert simultaneously and can be downloaded as a ZIP archive.

What's the maximum number of files I can convert at once?

Free users can convert several files per batch. PRO users enjoy unlimited batch sizes. For very large batches, your device's memory is the only practical limit.

Why choose ODF over other formats?

OpenDocument Formula offers standard math notation format without vendor lock-in. It's widely used for mathematical document creation and formula interchange, making it an excellent choice for most document needs.

Will my PPTX file be deleted after conversion?

No. Your original PPTX file is never modified or deleted. Xonvert creates a separate ODF copy — your source file remains untouched.
