Hey Product Hunt! 👋 I'm excited to share QubitTool with you today! The Problem: As a developer, I found myself constantly switching between dozens of bookmarked tools—one for JSON formatting, another for Base64 encoding, yet another for image compression. Each site had different UIs, some were slow, others were filled with ads, and a few even required sign-ups for basic features. The Solution: I built QubitTool to bring all these essential utilities into one clean, fast, and privacy-focused platform. Everything runs directly in your browser—your data never touches any server. What's inside: - 🔧 50+ free tools (and growing!) - 📝 JSON formatter, diff viewer, escape/unescape - 🖼️ Image compression, format conversion, cropping - 📄 PDF merge, split, compress - 🔐 Base64, URL encoding, MD5, JWT parser - ⏰ Timestamp converter, world clock - 📱 QR code generator with custom styling Why it's different: - ✅ 100% free, no sign-up required - ✅ Open-source (check out our GitHub!) - ✅ No ads, no tracking - ✅ Privacy-first: all processing happens locally - ✅ Built with Next.js for blazing-fast performance
