PdfFiller ou rien Très bonne expérience. Au début j'avais un peu de mal mais tout est venu très vite. Je l'utilise essentiellement pour ma paperasse professionnelle avec les administrations lorsque j'ai besoin de signer.Non seulement on fait des économies de papier mais en plus si on n'a pas d'imprimante ou qu'on se trouve sur le mobile ou la tablette on peut utiliser cette application. C'est top ! Pas besoin d'avoir un logiciel qui prend de la place dans l'ordinateur ou autre. Pas de risque de chopper un virus en téléchargeant !Facilité d'utilisation hors normes ! Je ne vois aucun point faible pour le moment. Si c'est le cas j'en ferai part.

So far so good. I had to adjust some of the checkmarks by raising/lowering them, moving them left/right, etc. But it all worked.
