Hey Product Hunt 👋 I built ConvertCase Tool to solve a simple but annoying problem — switching between different text formats quickly without using multiple tools. Most tools I found were either slow, cluttered with ads, or required signups. So I decided to build something faster, cleaner, and more complete. ConvertCase Tool brings together 150+ free text and developer tools in one place — from uppercase/lowercase converters to JSON formatting, text cleaning, and more. Everything runs instantly in your browser: • No ads • No signup • No data sent to any server The goal was simple: make everyday text tasks effortless for writers, developers, and anyone working with content. I’d really appreciate your feedback — what tools would you like to see next? 🚀
