Start With The Right Dimensions
Most heavy images are larger than the place where they will be displayed. Resize large photos before compression so the encoder has fewer pixels to store.
Use Balanced Quality
For web photos, quality between 75 and 82 is often a practical range. It reduces file size heavily while keeping visual artifacts hard to notice.
Export Modern Formats
WebP and AVIF can be much smaller than JPG or PNG for web delivery. Use PNG only when you need exact lossless output or compatibility with a specific workflow.
