說明 Thumbnail files (.thumb) are small preview images generated by various applications and operating systems. They contain reduced-size versions of larger images for quick browsing and preview purposes. Contenta Converter PREMIUM can batch convert thumbnail files to JPG, PNG, TIFF, and other standard formats. 差不多所有數碼相機都會有把圖像保存為JPEG的選項。JPEG格式支持每色8位(紅,綠,藍),文件大小也比較小。只要不使用重度壓縮,圖像質量不會受太大的影響。不過JPEG文件如果不斷被修改,保存的話,很有可能會退化。若您計劃以後修改照片圖像,或不能接受圖像失真,把它們保存為非JPEG的無損圖像格式的話會比較好。話雖如此,JPEG大致上是最適合網絡發佈的格式。
優點 Useful for recovering preview images from application caches and backups. 小的文件大小,非常受歡迎
缺點 Contains only low-resolution previews, not the original images. Format varies by source application. 質量損失
