How do I convert PowerPoint 97–2003 to PowerPoint (PPTX)?

Upload your PowerPoint 97–2003 file using the box above, confirm PowerPoint (PPTX) as the output format, then select Convert. The converted file is ready to download as soon as processing finishes — usually in a few seconds.

Is converting PPT to PPTX free?

Yes, and there is nothing to sign up for. Every conversion is free, there is no paid tier, and the limits are the same for everyone.

Will the quality change when converting to PowerPoint (PPTX)?

PPTX uses lossy compression, so some data is discarded to keep the file small. The default quality setting is tuned to be visually or audibly transparent for most material, and you can raise it in the conversion settings.

What happens to my file afterwards?

The uploaded file is deleted as soon as the conversion completes, and the converted file is removed automatically once its retention window ends. Download links are signed and expire within minutes.
