How to convert PPT to PPTX

  1. Add your PPT presentations

    Drop PPT files onto the box above, or click it to choose them. ToAny reads the file's contents to detect the type, so a wrong extension does not matter.

  2. PPTX is already chosen

    Press Convert and confirm the upload. The file is sent to the ToAny conversion server, converted to PPTX and removed afterwards.

  3. Download

    Save the PPTX, or download everything as one ZIP if you converted several files.

Why ToAny

  • Honest about uploads

    Browsers cannot convert PPT to PPTX reliably, so this pair runs on our server. You are asked before anything is sent, and the page says so plainly.

  • Removed afterwards

    The uploaded file and the result are deleted once the conversion has finished. Nobody looks at them and they are not used for anything else.

  • No account

    No sign-up, no email address and no watermark on the result.

PPT to PPTX: what to expect

PPT is a legacy format that newer tools open unreliably. PPTX stays editable in PowerPoint, Keynote and Google Slides. PPT is at home in compatibility with very old copies of PowerPoint; PPTX is the usual choice for slides that will be presented or edited.

PowerPoint presentation

PPTX is PowerPoint's format since Office 2007. Fonts, animations and layout can change when a deck is opened in Keynote or Google Slides, which is why finished decks are often shared as PDF.

Questions

Is my PPT file uploaded?

Yes, for this conversion. Browsers cannot convert PPT to PPTX reliably, so after you confirm, the file is uploaded over an encrypted connection to the ToAny conversion server, converted automatically and deleted once the conversion has finished. Most other conversions on ToAny run in your browser and upload nothing.

Is anything lost when converting PPT to PPTX?

Text is kept. Formatting carries over only as far as PPTX supports it.

Can I convert several PPT files at once?

Yes. Add as many as you like, convert them together and download each result or all of them as one ZIP.

How do I convert PPT to PPTX on Windows, Mac, iPhone or Android?

The steps are the same everywhere because ToAny runs in the web browser: open this page in a current version of Chrome, Edge, Safari or Firefox, add the PPT file, press Convert and save the PPTX. There is nothing to install.

Is there a file size limit?

Yes. Files sent to the conversion server are capped in size, and the page tells you when a file is too large to upload.
