Hangul to romanization
Paste Korean text and get it in Latin letters, using the system on Korean road signs. Sound changes are applied — 합니다 comes out as hamnida, not hapnida.
Why the same word has two spellings
Busan and Pusan are the same city. Korea switched systems in 2000, and older books, older people and personal names still use the old one. The full story is in Busan or Pusan?
Why it is not letter for letter
Romanization follows the sound, not the spelling. 감사합니다 is written with ㅂ but pronounced with ㅁ, so it comes out hamnida. This tool applies the common assimilations; a few rare ones it will miss.
Romanization is a crutch. Drop it as soon as you can — Hangul takes an afternoon.
