Hey Product Hunt! 👋 I’m the solo maker behind JW Tool Box. I built this project out of personal frustration. Like many of you, I was tired of Googling for a simple “PDF merger” or “JSON formatter” only to end up on sites stuffed with aggressive ads, paywalls, tracking scripts, or “Sign up to download” pop-ups. The web felt cluttered and greedy. So, I set out to build the antidote: a clean, privacy-first suite of tools that just works. No logins. No uploads to unknown servers. No nonsense. 💡 Fun fact: This project was mostly built using what I call “Vibe Coding.” I leaned heavily on AI coding assistants to accelerate development—so I could focus on the things that really matter: UX, performance, and privacy. I’m actively expanding the library, so please let me know if there are any small tools you’d love to see added. Your feedback means a lot—thank you for checking out JW Tool Box! 🚀✨
