Cette page vous guidera à travers le processus de conversion, en soulignant les avantages de l'ODT pour la pérennité et l'accessibilité de vos contenus. Nous veillerons à ce que la mise en page, les styles et les éléments complexes de vos documents soient préservés avec la plus grande fidélité possible, vous offrant ainsi une transition fluide et sans tracas vers un format libre et polyvalent.

  • Documents administratifs inter-organismes
  • Publications académiques multiplateformes
  • Échanges de maquettes en design éditorial

En France, en Belgique, en Suisse et au Québec, l'ODT est souvent privilégié par les administrations publiques et les institutions éducatives pour des raisons de souveraineté numérique et d'accessibilité, évitant ainsi la dépendance à un éditeur unique. Cela facilite grandement la collaboration et l'archivage à long terme des documents officiels.
