Quick and easy: JPG image conversion

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。

Contenta Converter PREMIUM lets you open, convert, and batch process JPG files into modern formats like JPG, PNG, TIFF, PDF, and more. Optimize file size, keep important metadata, and prepare images for web, print, or long-term archiving in just a few clicks.
