Why Compress Images?

Image compression reduces file size while preserving visual quality. Uncompressed images are the biggest cause of slow websites — a single photo can be 5-10 MB, while a compressed version looks identical at 200-500 KB. Faster loads improve user experience, reduce bounce rates, and boost SEO rankings through Core Web Vitals. Our compressor runs entirely in your browser, so your images are never uploaded to any server.

Who Needs Image Compression?

Web developers compress images for performance budgets and Core Web Vitals. Bloggers reduce image sizes for faster CMS platforms. Email marketers compress images for newsletters. Ecommerce stores optimize product photos. Social media managers compress images for upload limits.
