Frequently Asked Questions

Our tool utilizes cutting-edge WebAssembly technology. Instead of uploading your photos to a remote server, the compression algorithm is downloaded once into your browser. Your own processor performs the heavy lifting. This ensures total privacy: your sensitive data never travels across the internet, making it the most secure way to handle private photos.

Lossy compression significantly reduces file size by removing data that is invisible to the human eye—perfect for web optimization. Lossless compression preserves every single pixel but results in larger files. SuperCompressor intelligently optimizes this ratio to maintain perfect visual quality while reducing file weight by up to 90%.

WebP is a modern image format that provides superior compression for images on the web. By converting your images to WebP with the output format option, you significantly improve your site's loading speed. This is a crucial factor for SEO ranking and improving your Google PageSpeed Insights score.
