Understanding Image Compression
Image compression is the process of reducing file size while maintaining acceptable visual quality. There are two main types of compression:
Lossless Compression
Reduces file size without any quality loss. Perfect for images with sharp edges, text, or when original quality must be preserved. Common formats: PNG, WebP (lossless mode).
Lossy Compression
Achieves smaller file sizes by removing some image data. Best for photographs and complex images where slight quality reduction is acceptable. Common formats: JPG, WebP (lossy mode).
Choosing the Right Format
JPG/JPEG
Best for photographs and images with many colors. Excellent compression ratios but doesn't support transparency.
PNG
Perfect for images with transparency, sharp edges, or text. Larger file sizes but superior quality retention.
WebP
Modern format offering the best of both worlds: excellent compression with quality retention and transparency support.
