Hey everyone! 👋 I built DevToolBox because I was tired of jumping between 10 different websites for simple tasks like formatting JSON, compressing images, or generating QR codes. Every site had ads, popups, or forced me to create an account. So I made one clean place with 15+ free tools that all run in your browser — no data is ever sent to a server. Your data stays on your device. Some highlights: • JSON Formatter & Validator with syntax highlighting • Image Compressor — no upload needed • Password Generator with customizable strength • QR Code Generator with custom colors • Regex Tester, Base64 Encoder, UUID Generator, and more Everything is free, no sign-up, no ads. I'd love to hear what tools you find useful and what you'd like to see added. Try it out at toolbox-site.asia 🙌
