为什么要将图片转换为 WebP 格式？
WebP is a modern image format developed by Google that provides superior lossless and lossy compression for web assets. On average, WebP images are 26% smaller than PNGs and 25–34% smaller than comparable JPEGs, while maintaining full alpha transparency and rich color depth.
Converting your website and social media graphics to WebP drastically improves Google PageSpeed Insights, boosts Core Web Vitals (Largest Contentful Paint), and ensures fast mobile browsing without sacrificing visual quality. With PreviewYourPost, conversion happens 100% inside your browser with complete data privacy.
