將圖檔網上使用最佳化

在過去,「製作X幅圖片為適合網頁使用」是一項有價有市的服務,因為圖檔的大小很影響網站的下載速度。現在,網絡服務速度大大改善,也有賴於內容管理系統技術,網站內容已可輕鬆自行管理而毋須依賴程式員(例如使用WordPress),但圖檔的網絡最佳化鑑於網頁效能會影響搜尋排名,比起以往更加重要。針對此需求,Adobe Photoshop的Save for Web,讓你可以調節圖檔的格式、畫質、像素及大小等,輸出適合的網站使用版本,而整個過程你可透過與原圖並排的預覽比對下完成。

另外,不少人發現Facebook上載的圖片會跟原圖有色差,其實使用Photoshop Save for Web,確保Convert to SRGB已勾選,便可解決這有關色彩空間支援性的問題。
