65、影像壓縮標準(JointPhotographicExpertsGroup)是全球資訊網和其他線上服務上，在超文字標記語言(HTML)文件中顯示照片和其他連續色調影像常用的格式。BMP格式支援CMYK、RGB和灰階色彩模式，且不支援Alpha色版。與GIF格式不同的是，JPEG會保留RGB影像中所有的顏色資訊，但會選擇性地放棄資料以壓縮檔案大小。JPEG影像會在開啟時自動地解除壓縮。較高的壓縮層級會導致影像的品質較低，而較低的壓縮層級會導致影像品質較佳。在多數的情況下，最大的品質選項製造的結果，與原始影像幾乎沒有差別。本段直接摘自本段直接摘自 Photoshop 7 說明說明Evaluation
