JPG Image Conversion: Batch Convert, Resize & Organize
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.

Frequently Asked Questions about JPG
What is a JPG image file?
A JPG file is a type of image format used in various tools and workflows. With Contenta Converter PREMIUM you can convert JPG files to more common formats like JPG, PNG, or PDF without losing control over quality.
How do I convert JPG images to TIF?
Install Contenta Converter PREMIUM, add your JPG files to the input list, choose TIF as the output format, and click Convert. The software will process all selected files in a single batch.
Can I batch-process many JPG images at once?
Yes. Contenta Converter PREMIUM is built for batch processing and can handle hundreds or thousands of JPG images in one operation, using all available CPU cores.
When should I convert JPG images to another format?
Convert JPG images when you need better compatibility with web browsers, design tools, or printing services. Exporting to formats like JPG, PNG, or TIFF from Contenta Converter PREMIUM makes sharing and archiving much easier.
Is JPG the same as JPEG?
Yes, they are identical. The only difference is the file extension: .jpg uses three characters (a requirement of older Windows systems), while .jpeg uses the full name. Both refer to the same JPEG compression standard (Joint Photographic Experts Group).
When should I use PNG instead of JPG?
Use PNG when you need transparency, sharp text/line art, or lossless quality (screenshots, logos, diagrams). Use JPG for photographs and complex images where small file size matters more than pixel-perfect accuracy.
