Score: 5.3/10 (Innovation: 5, Technical: 5, Documentation: 4, Utility: 6)

A 100KB WASM SDK that runs client-side image and PDF compression before upload, targeting reduced S3/R2 storage and egress costs. The idea of shifting compression to the browser to cut cloud bills is practical and has a clear cost-saving appeal, though the offering is currently a thin wrapper around existing WASM codecs.

Target audience: frontend and full-stack developers handling user file uploads to cloud storage
