How JPG Compression Works Without Sacrificing Visual Quality

JPEG (Joint Photographic Experts Group) utilizes lossy discrete cosine transform (DCT) encoding. Standard digital cameras and mobile phones save photos with excessive chroma information and heavy embedded EXIF metadata that the human eye cannot discern on screen.

PixEnhance analyzes the high-frequency color variations and optimizes the quantization matrix locally on your machine. By discarding invisible redundancies while protecting edge contrasts and facial details, file sizes decrease by 60% to 85% with zero perceivable change in photo quality.

This optimization accelerates page loading speeds, lowers bandwidth consumption, and ensures seamless photo sharing across email attachments and web upload portals.

Quality Preset	Avg Compression	Recommended Use Case
High (85%–90%)	40% – 60% savings	Portfolio photography, print preparation
Medium (70%–80%)	65% – 80% savings	Websites, e-commerce, social media
Low (50%–65%)	80% – 90% savings	Email attachments, fast preview thumbnails

100% Client-Side Privacy Guarantee

Your images and personal documents are processed strictly in your local web browser using client-side canvas technology. Your files are never uploaded to any remote server, stored in any database, or viewed by third parties.
