Image compression is the process of reducing digital image file sizes without significantly affecting visual quality. Our image compressor uses advanced algorithms to make your images smaller while preserving their appearance.
Large images slow down websites dramatically. Each megabyte matters. When visitors wait more than 3 seconds for your page to load, many leave. Our image size compressor helps you meet modern speed expectations.
Lossless compression reduces file size while keeping 100% of the original quality. Perfect for logos, graphics with text, or when quality is non-negotiable.
Lossy compression creates much smaller files by removing some data. For most web images, the quality difference is nearly invisible, but the size reduction is substantial.
ZeroGrok lets you choose the perfect balance between size and quality.
Images often make up 50-90% of a webpage’s total size. Our image optimizer instantly cuts load times, keeping visitors engaged.
Google rewards faster websites with better rankings. Compressing images directly improves your Core Web Vitals scores, boosting your SEO performance.
Smaller images mean less storage space needed and lower bandwidth costs. Our pic compressor can reduce image sizes by up to 80% without visible quality loss.
