說明 |
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。 |
High Efficiency Image File Format (HEIF) is a container format for individual images and image sequences. It was developed by the Moving Picture Experts Group. |
優點 |
小的文件大小,非常受歡迎 |
MPEG claims that a HEIF image using HEVC requires about half the storage space as the equivalent quality JPEG. |
缺點 |
質量損失 |
