umeraslamwattoo/Resize-Image ? reverse-engineered prompt

Build me a full stack web app where people can upload images and quickly resize them, compress them to a smaller file size, convert between common formats like JPG, PNG, and WebP, and turn an image into a simple PDF. I want the app to feel like a handy online image tools site with separate pages for each tool, clear upload and download flows, and helpful text on the pages that explains what each tool does.

Also include a small blog or article section with an admin area where I can create, edit, and delete posts, and group them by topic so the tool pages can show related help content. Make it look clean and modern, work well on mobile, and use a React frontend with a Node and Express backend connected to MongoDB. If you need to look up current docs for anything, go ahead and do that.
