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. Use ImageSmith's free image optimizer to compress your Wix images directly in your browser — no account needed, no watermarks, and no ads. Target under 25,000KB per image for best results on Wix.
