Frequently asked questions
- What is the best image format for website speed?
- WebP typically offers 30% smaller files than JPEG at equivalent quality and is supported by all modern browsers. AVIF is even smaller but has less browser support. SnapOtter can auto-select the best format.
- How do images affect page load speed?
- Images are usually the largest assets on a web page. Unoptimized images can add seconds to load time, hurting both user experience and search engine rankings. Compression and format conversion are the most impactful optimizations.
- Should I use WebP or AVIF for my website?
- WebP has universal browser support and great compression. AVIF offers better compression but limited support in older browsers. For maximum compatibility, serve WebP with a JPEG fallback.
