Drop in a bilingual SRT (for example Chinese on one line and English on the next) and this tool splits it into a Chinese-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 anywhere. You don't pick a language: the tool detects each line by its characters, so it works even when the line order is inconsistent. It also handles Japanese or Korean paired with English, and any two-language pair via line-position mode.

The tool parses your SRT into individual cues, then looks at each text line and decides whether it is Chinese or English by the characters it contains. Lines with Chinese (Han) characters go into the Chinese track; lines without them 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 language rather than by line number, it still works when the order is flipped (English on top), when a cue has only one language, or when a file mixes both patterns — the kind of messy real-world subtitle files you get from ripped or reposted video. 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 use in a video editor or player, or export as TXT to get a clean, timecode-free transcript in a single language. The TXT option is useful when a client only wants the Chinese script or only the English script as plain text, with no subtitle formatting.
No. This tool runs 100% in your browser — your subtitle file never leaves your device and is never sent to a server. That means it also works offline once the page has loaded, and there is no file-size limit imposed by an upload. This is the same local-first approach behind GeekLink, our desktop subtitle app.
The tool is built for SRT, the most common bilingual subtitle format. You can also paste subtitle text directly. Output is available as SRT (with timestamps) or TXT (plain transcript, no timestamps).
No. The tool detects the language of each line automatically by looking at its characters, so you only provide the file. If your file has an unusual layout, you can switch to "By line position" mode, which sends the first line of every cue to the Chinese file and the rest to the English file.
Yes. Auto-detect mode works for any pairing of a CJK language (Chinese, Japanese, or Korean) with a Latin-script language such as English, Spanish, or Portuguese — it routes the CJK line and the Latin line to separate files. For two languages that both use the Latin alphabet (for example English and Spanish), use "By line position" mode, which splits by line order and works for any pair.
Yes. Timestamps are copied unchanged into both output files, so the Chinese-only and English-only subtitles stay perfectly in sync with the original video.
This splitter works on subtitle files you already have. If your subtitles are burned into the video (hardcoded) and you have 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.
