Technical Architecture
PNG vs JPG - When to Use Each
**Use PNG when**: - Need transparency - Have logos, graphics, text - Editing repeatedly (lossless) - Quality is critical - File size doesn't matter **Use JPG when**: - Photos for web/email - Need small file sizes - don't need transparency - Slight quality loss okay - Final delivery (not editing) **File Size Comparison**: - Photo PNG: 10MB - Same photo JPG 90%: 800KB - **12.5x smaller!** **Quality Difference**: Barely noticeable on photos. JPG compression is designed for photographic images.
How Compression Works
**PNG Compression** (Lossless): - Keeps every pixel exactly - Large file sizes - Perfect quality - Like a ZIP file for images **JPG Compression** (Lossy): - Throws away 'unnecessary' detail - Much smaller files - Slight quality loss - Smart about what to discard **The Trade-off**: JPG analyzes colors and removes subtle variations human eyes won't notice. Result: 80-95% smaller files with quality that looks nearly identical! **Quality Settings**: - 100%: Best quality, larger files - 90%: Sweet spot (default) - 80%: Smaller, visible artifacts - 60%: Tiny files, noticeable quality loss
Transparency Handling
**The Problem**: JPG doesn't support transparency! **What We Do**: 1. Detect transparent pixels in PNG 2. Replace with solid color (default: white) 3. Convert to JPG **Background Color Options**: - White (default) - safest choice - Black - for dark images - Custom color - match your website **Can't preserve transparency?** No! it's JPG format limitation. For transparency, must use PNG (or WebP). **Example**: Logo with transparent background → becomes logo with white (or chosen color) background in JPG.
