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 |
