What format is best for web images?

WebP is the best all-around choice for web images in 2024. It offers 25-35% smaller files than JPG with excellent quality. AVIF is even smaller but has less browser support. JPG remains the safest legacy fallback.

What quality setting should I use for web images?

75% quality is the sweet spot for most web images, visually indistinguishable from the original but significantly smaller. Use 85-90% for hero images and 60-70% for thumbnails.

How much can I reduce image file size for the web?

Typically 60-90% file size reduction is achievable by combining resizing, format conversion to WebP, and quality optimization. A 5 MB source photo can often become 200-500 KB.
