研究方向

The issue requests compression for images larger than 5MB. Investigate using sharp or similar library for Cloudflare Workers. Review the current upload handling code in the repository to determine where to add size check and compression logic. Consider using a library that supports both JPEG and PNG compression. Look at how Cloudflare Workers allow for image transformation and streaming. A possible implementation could check image size during upload and apply compression if exceeding 5MB.
