Technical Specifications & Quality Settings
Compression Algorithms
JPEG Compression
Uses Discrete Cosine Transform (DCT) to compress images by removing less visible information. Quality settings from 1-100% control the balance between file size and visual quality.
PNG Compression
Uses lossless DEFLATE algorithm. No quality loss but larger file sizes. Best for images with sharp edges and transparency.
WebP Compression
Advanced VP8 codec provides superior compression. Supports both lossy and lossless modes with better efficiency than JPEG/PNG.

Quality 70-90%
Good balance for web use. Suitable for most online applications with reasonable file sizes.

Image Optimization Best Practices
Web Performance Optimization
Modern Format Strategy
Use WebP as primary format with JPG/PNG fallbacks. This approach provides the best compression while maintaining compatibility with older browsers.
Responsive Image Optimization
Create multiple sizes for different screen resolutions. Use appropriate formats: WebP for modern browsers, optimized JPG for fallback.
Core Web Vitals Impact
Properly optimized images directly improve Largest Contentful Paint (LCP) scores, contributing to better search engine rankings and user experience.
Mobile Considerations
HEIC Compatibility
Convert iPhone HEIC photos to JPG or PNG for universal sharing. HEIC offers 50% better compression but isn't supported everywhere yet.
Mobile-First Optimization
Prioritize smaller file sizes for mobile users. Use progressive JPEG encoding and consider WebP for modern mobile browsers.
Bandwidth Considerations
Mobile users often have limited bandwidth. Optimize images more aggressively for mobile while maintaining acceptable quality levels.
