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 Control Guide

Excellent quality for professional photography, printing, or archival storage. Larger file sizes.

Quality 70-90%

Good balance for web use. Suitable for most online applications with reasonable file sizes.

Quality 50-70%

Optimized for fast loading. Good for thumbnails, email attachments, or bandwidth-limited situations.

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.
