Dans le monde professionnel et académique francophone, la présentation est reine. Souvent, nous créons des diaporamas élaborés avec PowerPoint (PPT), mais il arrive un moment où l'on souhaite figer cette présentation, la rendre non-modifiable et prête à être diffusée ou projetée sans risque d'altération. C'est précisément là qu'intervient le format PPS (PowerPoint Show). Convertir votre PPT en PPS, c'est transformer un document de travail en un spectacle autonome. Idéal pour des kiosques interactifs, des démos en boucle lors de salons, ou simplement pour garantir que votre audience voit exactement ce que vous avez préparé, sans barre d'outils ni mode édition. Notre outil vous accompagne dans cette transition fluide, préservant l'intégrité de votre mise en page, de vos animations et de vos transitions, pour un rendu professionnel impeccable.
