Translate English subtitles to Korean
Last updated September 2026
Korean subtitles serve South Korea's highly online audience, and Korean-to-English is in high demand for K-drama, variety shows and K-pop content. This page explains how to turn an English .srt or .vtt file into Korean without uploading it anywhere: the translation runs on your own computer using the translation model built into desktop Google Chrome (138+) or Microsoft Edge. Korean is written in Hangul, a featural alphabet grouped into syllable blocks, and does use spaces between words. Below are the steps plus Korean-specific things to check before you publish.
How to do it
- Open the translator in desktop Chrome 138+ or Microsoft Edge — the link on this page presets English → Korean.
- Drop your English .srt or .vtt file onto the page (or click to choose it). Nothing is uploaded; the file is read locally.
- Confirm the languages show English → Korean and press Translate. The first time, the browser downloads the English–Korean model once, which can take a minute.
- Watch cues translate in place. Timestamps, cue numbers and tags such as <i> stay exactly as they were.
- Download the Korean file (same format as the input) and load it in your player or upload it to your video platform.
Tips
- Korean has several speech levels. The model picks one per line, so a character may switch between polite and casual — fix main characters for consistency.
- Hangul is compact; translated lines usually fit comfortably within the original timing.
- Save as UTF-8 — legacy EUC-KR/CP949 files from older Korean software are a common cause of garbled text.
FAQ
Which Korean speech level is used?
The model infers it per line from the English. Short subtitle lines give it little context, so expect some mixing of polite and casual forms that you may want to standardise.
Is translating English subtitles to Korean really free?
Yes. There's no account, no per-file limit and no paid tier — the translation is done by your browser's built-in on-device model, so there's no server cost to pass on.
Does it work on my phone?
Not at the moment. The built-in Translator API is only available in desktop Google Chrome 138+ and Microsoft Edge. Mobile browsers, Firefox and Safari don't offer it yet.
