Build a PDF to Image Converter with Claude Code

Build a PDF to Image Converter web app. People search for "pdf to image converter" about 161,000 times a month, plus related searches like "convert pdf to jpg", "pdf to png converter", "extract images from pdf". The goal is a tool that ranks for those searches and makes money.

What it should do:
Build a PDF to image converter web app. Create a homepage with a large upload zone saying 'Drop your PDF to convert to images'. When users upload a PDF, show a preview of all pages with checkboxes to select which pages to convert. Add output format options (JPG, PNG, TIFF) and quality settings (Low, Medium, High). Display conversion progress with a progress bar. After conversion, show thumbnail previews of all converted images with individual download buttons or zip download option. Use a clean design with red and blue accents. Focus on the PDF upload and page selection flow first.

How to build it:
1. Read this folder first. If it is empty, set up Next.js (App Router, TypeScript, Tailwind). Write a short PLAN.md with the pages, components, any library or API you need, and what you are leaving for later. Then build.
2. Put the tool itself on the homepage so a visitor can use it within seconds, with no sign-up. Do the processing in the browser where you can, so it is fast and cheap to run. Look at how SmallPDF, ILovePDF, PDF24 do it and make ours simpler and faster.
3. Make it rank. Use "pdf to image converter" in the title tag, H1 and meta description. Under the tool, add a short how-to and an FAQ with FAQPage schema, and add a sitemap and robots.txt. Scaffold these programmatic pages from one template and a data file: /convert-pdf-to-[image-format], /pdf-to-image-for-[use-case], /extract-[page-number]-from-pdf.
4. Monetisation: Freemium: 3 PDFs/day, $7/mo unlimited + batch conversion. Add a pricing page and the free usage limit, and leave Stripe checkout as a clearly marked stub with the environment variables it needs.
5. Run it locally and test the main flow end to end, including edge cases like empty input and very large files. Fix what breaks, then finish with a summary of what works, what is stubbed and how to deploy it to Vercel.

Paste it into Claude Code in an empty folder. It plans first, so read PLAN.md and steer before it starts building.
