Everything you need to know to optimize your images like a pro
Image compression is the process of reducing file size by removing redundant data. When you take a photo, the file contains much more information than the human eye can perceive.
Compression algorithms identify and remove this "invisible" information, drastically reducing the file weight while maintaining a visually identical appearance.
💡 Key fact: A 5MB photo can be reduced to 500KB (90% less) without you noticing any difference.
Lossy Compression: Permanently removes data that the human eye hardly perceives. Ideal for photos, allowing 60-90% reductions. JPEG and WebP use this method.
Lossless Compression: Compresses without eliminating any data. The decompressed image is bit-for-bit identical to the original. PNG and GIF use this method, with typical reductions of 10-30%.
🎯 Which to choose? For photos: Lossy JPEG/WebP at 85%. For logos/graphics with sharp edges: Lossless PNG.
After years of research and millions of processed images, we have determined that 85% JPEG quality is the optimal point for most photographs.
At this level:
That's why our slider starts at 85% by default.
Images represent 50-70% of a webpage's total weight. Optimizing them correctly can:
