Image optimization tools make website and app images smaller and correctly sized: they compress files, convert them to WebP or AVIF for browsers that support them, resize and crop on request, and deliver the result quickly. Paid options are hosted image CDNs and APIs priced by bandwidth, credits or compressions; the open-source side offers self-hosted image servers you put behind your own CDN, plus libraries and build-time compressors.
Prices and free tiers as checked, dated on each review.
