Tani DevTool

About

Free web tools, no sign-up required

Tani DevTool (teck-tani.com) is a free collection of web utilities open to everyone — no registration needed. It is designed so that common conversion, calculation, and generation tasks can be handled instantly in your browser.

1About the Service

Tani DevTool offers 72 tools — QR code generator, JSON formatter, image compressor, Base64 encoder, regex tester, and more — in both Korean and English.

Every tool runs entirely in your browser. The text, images, and files you enter are never sent to the Service's servers; all results are produced on your own device.

A few tools call external APIs (for example, lottery draw data or IP address lookup) only when you actively use that specific tool.

2Operating Policy

  • •All tools are free, with no usage limits.
