What is the Korean Name Romanizer?
The Korean Name Romanizer converts a Korean name into romanized English so you can use it on passports, driver's licenses, EMS international mail, overseas admission and job applications, and contracts. It follows the Revised Romanization of Korean (Ministry of Culture Notice No. 2000-8): each Hangul syllable is decomposed into initial, medial, and final jamo, and each jamo is mapped to its assigned Latin letters. The tool computes this directly from the Unicode syllable-decomposition formula with no dictionary, so any Korean name converts instantly.
Surnames in particular often use a conventional spelling rather than the strict rule (이 → Lee, 박 → Park, 최 → Choi), so the tool also lists the spellings most frequently seen in passport records, ordered by usage frequency. It shows passport (GILDONG HONG), hyphenated (Gil-Dong), spaced, and Western-order formats side by side, and reveals the jamo breakdown transparently so you understand exactly why a name is spelled the way it is. All processing happens in your browser, so the name is never sent to a server.
Key Features
Real-time romanization
Type a Korean name and it is converted instantly via the Revised Romanization rules (jamo decomposition), with the surname and given name split automatically. Compound surnames are detected too.
Recommended surname spellings + frequency
For surnames like 이 → Lee/Yi/Rhee or 박 → Park/Bak, the tool lists candidates ordered by usage frequency. Pick one and it is applied to the results immediately.
Formats by use case
See passport (surname + given, caps), hyphenated (Gil-Dong), spaced, and Western order (given + surname) at once. Toggle name order and letter case as needed.
Transparent syllable breakdown
A table shows each syllable's initial, medial, and final jamo and the romanized output, so you can understand at a glance why it is spelled that way.

Use Cases
Choosing a passport name
When applying for a first passport, decide an English surname and given name that match your family's spelling. Use the passport-style result (caps, surname first) as a reference for the form.
EMS / international mail
Sending or receiving items abroad requires an English name. Pick a spaced or hyphenated spelling that fits the shipping label format.
Overseas admission & job documents
Check your spelling when you need to use it consistently with your passport on university applications, English resumes, and visa forms.
Flights & hotel bookings
If the spelling on a ticket differs from your passport, boarding or check-in can fail. Verify it matches the passport-style spelling in advance.
Frequently Asked Questions
Can I use this result directly as my passport name?
It's fine as a reference, but it is not an official spelling. This tool suggests the most common romanization based on the Revised Romanization of Korean. Because a passport name is difficult to change later and families usually keep one consistent surname spelling, match it to your family and existing documents first, then confirm with the official passport guidance.
My surname is ‘이’ — why do Lee, Yi, and Rhee all appear?
Strictly by the romanization rules ‘이’ is ‘I’, but on passports Lee is overwhelmingly the most common, with Yi and Rhee also used. So the tool lists candidates by usage frequency and also shows the rule-based spelling. If your family already uses a spelling, keep it consistent with that.
Are batchim / consonant-assimilation sound changes applied?
For passport names, MOFA recommends NOT reflecting sound changes such as consonant assimilation or palatalization, and this tool follows the same approach, joining each syllable's spelling as written. For example, ‘학년’ is written ‘Haknyeon’ as spelled, not as pronounced.
Why does the passport format put the surname first and in capitals?
Korean passports record the Surname and Given name separately, and the romanized name is typically shown in capitals. That's why the passport result appears surname-first and uppercase, like GILDONG HONG. Use the exact same spelling on flight tickets so boarding goes smoothly.
Is the name I type sent to a server?
No. All conversion happens entirely in your browser. The name you enter is never sent to a server, stored, or collected, so you can use it without privacy concerns.
Do compound surnames or single-syllable given names work?
Yes. Common compound surnames such as 남궁, 제갈, 선우, 황보, 사공, and 독고 are detected automatically and split off as the surname, and single-syllable given names (e.g., 김민) convert correctly. You can type the surname and given name together and it will split them for you.
