How Browser-Based Image Compression Works

Image compression reduces image byte size by removing non-essential metadata (EXIF tags) and using smart compression algorithms to reduce color table complexity while preserving perceptual fidelity for the human eye.

Security & Privacy Assurance

Images are drawn and compressed locally on your computer using the HTML5 Canvas API. Your photos are never uploaded to any remote server.
