Drop in a bilingual Korean + English SRT and this tool splits it into a Korean-only file and an English-only file — download either as SRT or as plain TXT. It runs entirely in your browser, so your subtitle file is never uploaded. You don't pick a language: it detects Korean lines by their Hangul characters and separates them from the English lines, even when the line order is inconsistent.

The tool parses your SRT into individual cues, then reads each text line and decides whether it is Korean or English by the characters it contains. Lines written in Hangul go into the Korean track; lines in the Latin alphabet go into the English track. The timestamps are copied unchanged, so both output files stay perfectly in sync with the video.
Because it classifies by script rather than by line number, it still works when the English line comes first, when a cue has only one language, or when a file mixes patterns — the kind of messy real-world files you get from ripped or reposted K-drama and variety content. If auto-detection ever gets it wrong, switch to By line position mode.
Yes. Each side has its own download buttons. Export as SRT to keep the timestamps for a video editor or player, or export as TXT to get a clean, timecode-free transcript in a single language. The TXT option is handy for study material, translation checks, or when a client only wants the Korean script or only the English script as plain text.
No. This tool runs 100% in your browser — your subtitle file never leaves your device and is never sent to a server. It works offline once the page has loaded, and there is no upload size limit. This is the same local-first approach behind GeekLink, our desktop subtitle app.
It checks each line for Hangul characters. A line containing Hangul is routed to the Korean track; a line written in the Latin alphabet goes to the English track. You do not need to select a language.
No. It detects each line automatically by its characters, so you only provide the file. If your file has an unusual layout, switch to "By line position" mode, which sends the first line of every cue to the Korean file and the rest to the English file.
Yes. Timestamps are copied unchanged into both output files, so the Korean-only and English-only subtitles stay perfectly in sync with the original video.
This splitter works on subtitle files you already have. If the subtitles are burned into the picture (hardcoded) with no SRT, you need OCR extraction first. GeekLink, our desktop app for Mac and Windows, extracts hardcoded subtitles via OCR, transcribes speech, translates, and burns subtitles in — including batch processing across many videos.
