The Impact of Images on Web Performance
Images account for over 60% of total page weight on modern websites. Unoptimized images are the single biggest cause of slow Largest Contentful Paint (LCP), leading to higher bounce rates and degraded Google search rankings.
Best Practices for Web Image Optimization
1Choose the Right Format: Use WEBP or AVIF for website photos; use SVG for vector logos and icons.
2Dimension Appropriately: Never serve a 4000px camera photo inside a 400px card. Resize your pictures to match display containers.
3Compress Responsibly: Compress images to 80–85% quality to eliminate invisible bloat.
4Strip EXIF Metadata: Remove camera settings, GPS coordinates, and embedded thumbnails to save kilobytes on every file.
