Compress WebP Images for Wix
Wix automatically processes and serves images through its CDN, but uploading pre-optimized images still improves initial load times and ensures the best quality baseline. Modern image format developed by Google offering 25–35% smaller files than JPEG/PNG at equivalent visual quality. Use ImageSmith to compress your WebP images to the ideal file size for Wix — target under 25,000KB for optimal performance. Processing is fully browser-based — no server uploads, no privacy risk.
