Frequently Asked Questions

Our advanced optimizer typically reduces file sizes by 40-85% depending on the image type and current compression level. JPEG photos see 30-60% reduction, PNG graphics can be compressed by 50-85%, and WebP images get 20-40% further optimization. All while maintaining 100% visual quality.
Absolutely! Google uses Core Web Vitals as a ranking factor, and image optimization directly improves Largest Contentful Paint (LCP) and Cumulative Layout Shift (CLS). Faster loading images boost user experience, reduce bounce rates, and improve search engine rankings. Our optimizer helps achieve perfect PageSpeed Insights scores.
Yes! Our optimizer supports JPEG, PNG, and WebP formats. It automatically applies format-specific optimizations - progressive JPEG encoding, PNG palette optimization, and WebP lossless compression. The output maintains the same format as your input for maximum compatibility.
Completely safe! Our optimizer uses advanced lossless compression that preserves 100% image quality while dramatically reducing file size. All processing happens locally in your browser - no uploads, no data collection, complete privacy. Used by Fortune 500 companies and professional web developers worldwide.
Our advanced optimizer often achieves better compression ratios than traditional tools while maintaining superior quality. Unlike cloud-based services, everything processes locally for privacy and speed. We use cutting-edge algorithms including advanced mathematical optimization and proven psychovisual modeling techniques.
Perfect for mobile optimization! Our optimizer is especially effective for mobile web performance where bandwidth and loading speed are critical. Optimized images load 3-5x faster on mobile connections, dramatically improving user experience and Core Web Vitals scores on mobile devices.
Excellent for e-commerce! Product images often have large file sizes that slow down category pages and product galleries. Our optimizer maintains the visual quality customers expect while reducing load times that directly impact conversion rates and SEO performance.
Image optimization is crucial for Core Web Vitals success. Smaller images improve Largest Contentful Paint (LCP) by loading faster, reduce bandwidth usage affecting First Input Delay (FID), and prevent layout shifts improving Cumulative Layout Shift (CLS). Google considers these metrics for search rankings.
