How JPG Compression Works

JPG compression uses a lossy compression algorithm that reduces file size by removing details that are difficult for the human eye to perceive. Higher compression quality preserves more details but results in larger files; lower quality removes more details and produces smaller files.

JPG Compression Recommendations for Different Scenarios

Social media: Recommended quality 60%-75%, as platforms typically compress again
Storage & backup: Recommended quality 85%-95%, ensuring higher image quality
Design originals: Not recommended to compress, keep original quality
