ABOUT THE PROJECT
Devotools is a small collection of free tools I kept needing myself and didn't want to pay for or sign up to use. It converts PDFs to Word and back, edits PDFs in the browser (text, signatures, drawing, rotating and reordering pages), turns a rough request into a structured JSON prompt for AI tools, and makes dynamic QR codes whose target you can change after printing. The site is built with Next.js; the PDF to Word conversion runs on a Python service inside the same Docker image, and the JSON prompter uses Gemini.
