What is Image Compression?

Image compression is the process of reducing file sizes by removing unnecessary metadata and optimizing pixel data structures without sacrificing visual clarity. When you upload photos or graphics to websites, heavy image files slow down page load times, consume bandwidth, and degrade mobile user experience.

Our browser-based compressor uses smart lossy and lossless algorithms natively in your browser memory. By leveraging HTML5 Canvas rendering and optimized WebP/JPEG quantization, files are shrunk by up to 80% while remaining completely visually identical to the human eye.

By compressing your JPG, PNG, WebP, and GIF images prior to publishing or emailing, you boost your site Google PageSpeed score, meet strict email attachment size limits, and save valuable disk storage.
