Aujourd\u2019hui, nous allons vous parler de l\u2019importance d\u2019utiliser des images optimis\u00e9es dans votre design web<\/strong>.<\/p>\n

C\u2019est un aspect essentiel lors de la cr\u00e9ation du design d\u2019un site<\/strong> web<\/strong>, car il influence directement des \u00e9l\u00e9ments cl\u00e9s tels que le temps de chargement et le risque de p\u00e9nalisation, que ce soit par vos clients, les utilisateurs ou m\u00eame Google.<\/p>\n

Si vous envisagez de nous confier la cr\u00e9ation de votre site web<\/strong>, voici quelques astuces \u00e0 suivre pour optimiser au maximum le rapport entre image, qualit\u00e9 et poids.<\/p>\n

1. Optimiser les images sans perte de qualit\u00e9 dans votre design web<\/h2>\n

C\u2019est la base \u00e0 ne jamais n\u00e9gliger, m\u00eame si vous ne retenez qu\u2019un seul conseil de cette liste. Utilisez l\u2019un de ces deux logiciels : ImageOptim pour OS X ou FileOptimizer pour Windows et Linux, afin d\u2019automatiser l\u2019optimisation de vos images.<\/p>\n

Il vous suffit de glisser-d\u00e9poser vos fichiers dans l\u2019application, le temps d\u2019un caf\u00e9, et le tour est jou\u00e9.<\/p>\n

C\u2019est rapide, sans effort, et vous obtenez des images parfaitement optimis\u00e9es.<\/p>\n

2. Choisir la bonne taille<\/h2>\n

Utiliser des images aux dimensions inadapt\u00e9es est une erreur fr\u00e9quente, mais aux cons\u00e9quences d\u00e9sastreuses.<\/p>\n

On pense souvent qu\u2019une image affich\u00e9e \u00e0 la bonne taille \u00e0 l\u2019\u00e9cran est suffisante, alors qu\u2019en r\u00e9alit\u00e9, le navigateur peut charger une version bien plus grande (et donc plus lourde), tout en l\u2019affichant en petit format.<\/p>\n

Les dimensions de vos images doivent donc correspondre exactement \u00e0 l\u2019espace qu\u2019elles occupent sur le site, ni plus, ni moins.<\/p>\n

3. Enregistrer pour le web<\/h2>\n

Les professionnels du design web<\/strong> connaissent d\u00e9j\u00e0 cette option, qui permet de gagner un temps pr\u00e9cieux si elle est bien int\u00e9gr\u00e9e \u00e0 votre workflow.<\/p>\n

Il s\u2019agit simplement d\u2019enregistrer vos images destin\u00e9es au web dans un format optimis\u00e9.<\/p>\n

Voici une comparaison, de droite \u00e0 gauche, d\u2019images enregistr\u00e9es pour le web \u00e0 100, 70, 50 et 20 % de qualit\u00e9. Selon la taille d\u2019origine, la diff\u00e9rence sera plus ou moins visible.<\/p>\n

Il existe de nombreuses th\u00e9ories sur le pourcentage de qualit\u00e9 id\u00e9al, mais le mieux est de faire confiance \u00e0 votre \u0153il : testez, enregistrez, zoomez, comparez\u2026 C\u2019est le meilleur moyen d\u2019affiner votre regard et d\u2019obtenir un rendu parfait.<\/p>\n

\"tama\u00f1o<\/a><\/p>\n

4. Ces images sont-elles vraiment n\u00e9cessaires dans mon design web ?<\/h2>\n

C\u2019est une question essentielle, parmi d\u2019autres, lors de l\u2019analyse d\u2019un projet web<\/strong>. Un bon design web<\/strong> commence toujours par une analyse des besoins : il ne s\u2019agit pas de multiplier les images, mais de s\u2019assurer de leur r\u00e9elle utilit\u00e9.<\/p>\n

5. Utiliser le format adapt\u00e9<\/h2>\n

Il existe diff\u00e9rents formats d\u2019image, chacun avec ses sp\u00e9cificit\u00e9s, ses avantages et ses limites.<\/p>\n

Mieux les conna\u00eetre permet de choisir le format le plus pertinent selon chaque usage.<\/p>\n

Si vous avez la moindre question, n\u2019h\u00e9sitez pas \u00e0 nous appeler \u00e0 notre studio de Barcelone<\/strong> : nous vous accompagnerons avec plaisir dans toutes vos d\u00e9marches.<\/p>\n
