Split an SRT File Online
Choose one split point and turn a long subtitle file into two clean SRT files. Keep the master timeline or restart the second part at 00:00, and decide what happens to the caption in the middle.

Exporting requires signing in and uses one project of your plan (free: 3 projects per UTC day, up to 100 captions per project). Uploaded files are deleted after 24 hours. Timecodes accept HH:MM:SS.mmm and HH:MM:SS,mmm.
How to split an SRT file in three steps
- Upload the SRT exported for the full-length source.
- Enter the split point, for example
00:12:30.000, and pick the timing for part 2. - Review both previews, then export one ZIP with the SRT and TXT of each part plus a manifest.
When splitting at one point is the right tool
- Course modules — one subtitle file per lesson cut from a single recording.
- YouTube chapters — split the transcript where the chapter markers sit.
- Podcast episodes — separate the interview from the outro, or an ad break from the conversation.
- Long webinars — hand the first half to one editor and the second half to another.
If you only need the middle of a file, use the split SRT by timestamp tool instead: it extracts one start-to-end range and discards the rest.
The caption in the middle
Exactly one caption usually straddles the split point. Trimming puts its first half at the end of part 1 and its second half at the start of part 2, so no words disappear. Excluding removes it from both files. The preview above shows how many captions are affected before you export.
SRT splitter FAQ
- What is the difference between splitting at a point and extracting a range?
- Splitting at a point produces two files that together cover the whole source: everything before the timestamp and everything after it. Extracting a range produces one file and throws the rest away. Use the timestamp splitter for a range, and this page when you need both halves.
- Which part keeps the original timecodes?
- Part 1 always keeps the master timeline, because it starts at 00:00 anyway. For part 2 you choose between restarting at 00:00 from the split point and keeping the master timeline.
- How is the caption that crosses the split point handled?
- By default it is trimmed: the first half ends at the split point and the second half starts there. You can also exclude it from both parts, which is useful when a sentence would read badly cut in two.
- Are the cues renumbered?
- Yes. Both parts are renumbered continuously from 1, and no timestamp can be negative, so each file drops straight into an editor or a captioning tool.
- Which file formats are supported?
- Input is SRT with HH:MM:SS,mmm or HH:MM:SS.mmm timings, with or without a UTF-8 BOM and with LF or CRLF line endings. Export produces SRT, plain-text TXT and a manifest CSV inside one ZIP.
- Do I need an account to download the two parts?
- Yes. The split preview is free, but building the ZIP requires signing in. The free plan includes 3 projects per UTC day with up to 100 captions per project; Studio removes both limits.
- Is my file stored after the split?
- Uploaded files and the exported ZIP are stored only for processing and deleted after 24 hours. Your account keeps the project metadata that the plan limits are checked against.
Splitting into more than two parts?
One row per clip in a CSV — name, start, end — and every clip leaves with its own re-timed SRT and TXT in one ZIP.
