Score: 5.5/10 (Innovation: 4, Technical: 4, Documentation: 8, Utility: 6)

PixelShrink is a browser-based local image compressor that processes JPEG, PNG, WebP, and GIF files entirely client-side using the File API and Canvas, with no uploads or tracking. It offers quality adjustment, resizing, ZIP download, and offline support via a service worker. While not technically novel—similar tools exist—its emphasis on privacy and honest handling of already-optimized files makes it a solid, well-documented utility.

Target audience: general users, frontend developers, privacy-conscious users
