Modifier le format d’une photo : quelle extension d’image choisir ?<\/h2>\n

Sachez que, tout comme les fichiers musicaux ou vid\u00e9os, les images disposent elles aussi de plusieurs formats ou extensions. Voici les 4 extensions \u00e0 connaitre pour bien modifier le format d’une photo<\/strong> :<\/p>\n

– le format JPG<\/strong> : ce format permet d’atteindre un niveau compression in\u00e9gal\u00e9. Il permet de choisir le niveau de compression et donc de d\u00e9gradation d’une photo. Ce format est tr\u00e8s pratique et fonctionne tr\u00e8s bien pour compresser un visuel qu’on juge trop lourd, d’o\u00f9 sa position de format standard. Nous vous conseillons de l’utiliser pour des photos ou des visuels complexes <\/strong>avec beaucoup de d\u00e9tails et\/ou de couleurs<\/strong>.<\/p>\n

– le format PNG<\/strong> : le format PNG permet de g\u00e9rer les transparences et donc de n’afficher que la partie souhait\u00e9e d’un visuel, contrairement au format JPEG qui comporte forc\u00e9ment un fond (blanc ou autre). Cette caract\u00e9ristique lui vaut d’\u00eatre le format pr\u00e9pond\u00e9rant sur le web. Nous vous conseillons de l’utiliser sur des visuels aux dimensions raisonnables<\/strong> et sur des ensembles de couleurs peu complexes<\/strong> comme des aplats de couleurs.<\/p>\n

– le format BMP<\/strong> : ce format et l’un des tous premiers utilis\u00e9 sous Windows. Il n’apporte pas de compression \u00e0 vos photos et ne g\u00e9n\u00e8re donc pas de perte de qualit\u00e9. Par cons\u00e9quent, avec ce format vos photos p\u00e8sent plus lourd et prennent plus de place. Sachez \u00e9galement que changer le format d’une image vers le format BMP n’am\u00e9liorera pas la qualit\u00e9 de votre photo. Nous vous d\u00e9conseillons donc de l’utiliser<\/strong>.<\/p>\n

– le format GIF<\/strong> : convertir une image en GIF revient \u00e0 limiter votre photo \u00e0 256 couleurs, le nombre de couleurs maximum support\u00e9 par ce format. Vos photos seront donc de bien moindre qualit\u00e9. Le GIF permet d’obtenir des fichiers de petite taille mais \u00e9galement de cr\u00e9er des animations avec des visuels simples<\/strong>. Nous vous conseillons de l’utiliser uniquement dans ce dernier cas.<\/p>\n\t\t\t\t\n\t\t\t\t\"cadeaux\n\t\t\t\t<\/a>\n\t\t\t\t\n\t\t\t\t\"livre\n\t\t\t\t<\/a>\n\n","protected":false},"excerpt":{"rendered":"
