How it works

Is PPT to PPTX conversion free?

Yes. AnyConv365 lets you convert PPT to PPTX online for free with no account required.

Will my file quality be preserved?

We aim for the best practical fidelity for each pair. Preview the download before sharing when quality is critical.

Do you store my files?

Server-side source files are deleted immediately after a successful conversion. If conversion fails, the source file is retained for up to one hour for error diagnosis and then deleted automatically.

Do animations survive in PDF?

PDF captures a static view of slides. Transitions and animations are not preserved.

Why upgrade PPT to PPTX?

PPTX is the modern PowerPoint format with better support in current Office, Google Slides imports, and automation tools.

What to check

Privacy: Server-side source files are deleted immediately after a successful conversion. If conversion fails, the source file is retained for up to one hour for error diagnosis and then deleted automatically.

  1. 1 Compare the result with the original before deleting or sharing anything.
  2. 2 Check content, layout, timing, fonts, or folder structure that matters to your workflow.
  3. 3 Keep the source file as a backup because some format-specific features cannot transfer.
