What is Tani DevTool?
Tani DevTool is a free collection of web tools you can use right in your browser — no sign-up, no installation. It offers 72 tools in Korean and English, including image compression and conversion, QR code and barcode generation, developer utilities like JSON, Base64 and regex, character counting, unit conversion and more for everyday and work needs.
Any text, image or file you enter is processed only inside your browser and is never sent to our servers. Every result is generated directly on your device, so you can use the tools with peace of mind that your personal data stays private.
