뚝딱, Korea’s One-Stop Utility Shelf

Field notes

The site groups 26 named utilities behind a single Korean-language shelf, covering both ordinary file work and locally specific administrative calculations. Its scope includes WebP, JPEG, and PNG conversion; PDF extraction and image export; lunar-calendar conversion with intercalary-month support; and calculations for severance, annual leave, brokerage fees, and rent conversion. The page states that browser-processed files remain off the server, although the extract does not expose each tool’s interface or independently verify that behavior.
