JPG 图片调整尺寸
JPG (JPEG) is a compressed image format that balances file size and visual quality. When resizing JPG images, it's important to understand how compression affects the final result.
Compression vs Quality
JPG uses lossy compression, meaning some image data is permanently removed to reduce file size. Lower quality settings create smaller files but may introduce visible artifacts such as blurriness or blockiness. Higher quality settings preserve more detail but result in larger files.
What Makes JPG Different?
Unlike PNG, JPG does not support transparency and is best suited for photographs and complex images with gradients. It is widely used for web images, social media, and digital photography.
