PPTX to AVIConvertisseur — Rapide et Gratuit

Office Open XML Presentation (PPTX) stores slides, animations, embedded media, and speaker notes as zipped XML in the Microsoft PowerPoint format. Audio Video Interleave (AVI) interleaves audio and video streams in a Microsoft container format that supports many codecs but lacks modern streaming features. This conversion changes the file's encoding, compression method, and supported feature set. Metadata such as creation date and embedded colour profiles is preserved where the target format supports it. The result is a standard AVI file readable by any compatible application. 1converter handles PPTX-to-AVI conversion server-side: files are uploaded over HTTPS, processed on isolated cloud infrastructure, and the converted output is available for download for 24 hours before automatic deletion. No account is required for standard conversions.
