Common Use Case Scenarios
Website Hero Images & Banners
Primary: WebP (modern browsers) with JPEG fallback
Why: Large images need aggressive compression without quality loss
Settings: WebP quality 85-90, JPEG quality 80-85
E-commerce Product Photos
Primary: JPEG for main images, PNG for products needing transparency
Why: Balance between quality and loading speed is crucial
Settings: JPEG quality 85-90 for main images, PNG-8 for simple graphics
Blog Post Images

App Icons & UI Elements
Primary: PNG or SVG
Why: Need crisp edges and often transparency support
Settings: PNG-8 for simple graphics, PNG-24 for complex transparent images
Social Media Content
Primary: JPEG for photos, PNG for graphics with text
Why: Platform requirements and file size limits
Settings: JPEG quality 80-85, stay under platform file size limits
Email Newsletter Images
Primary: JPEG (best compatibility)
Why: Email clients have limited format support
Settings: JPEG quality 75-80, keep files small for faster loading

Important Limitations to Consider
WebP Browser Support
While modern browsers support WebP, older versions may not. Always provide fallbacks for critical images or use progressive enhancement.
File Size Considerations
PNG files can be significantly larger than JPEG for complex images. WebP offers the best compression but requires proper fallback strategies.
Platform Restrictions
Some platforms (email clients, certain CMS systems) have limited format support. Always check platform requirements before deciding.
