How to split an SRT file
One file becomes several parts in three steps.
- 1
Open the subtitle file
Drop the file, pick it from your device or paste the text. SRT, WebVTT, ASS and other common subtitle formats are read.
- 2
Choose where to split
Split into N equal parts, at specific timecodes, every N minutes or every N subtitles. Decide whether each part restarts at 00:00 or keeps its original times.
- 3
Download the parts
Every part is listed with its time span and number of subtitles. Preview the parts, then download them one by one or all together as a ZIP.
What the subtitle splitter does
Four ways to cut a subtitle file, with times that match the cut video.
Split at timecodes
Enter the exact timecodes at which the video is cut, and the subtitles are cut at the same points.
N equal parts
Divide the file into two, three or more parts of equal length, by time or by number of subtitles.
Every N minutes
Start a new part after a fixed number of minutes, for example every 10 minutes.
Every N subtitles
Start a new part after a fixed number of subtitles, for example every 100 subtitles.
Restart at 00:00
Each part can start again at 00:00, which is needed when the video is split too.
Video length for equal parts
Enter the length of the video so equal parts are measured on the video, not on the last subtitle.
Overview of all parts
Every part is listed with its time span and number of subtitles and can be previewed.

How do you split an SRT file into two or more parts?
A subtitle file has to be split whenever the video it belongs to is split: a long recording cut into chapters, a film divided into two files, or a lecture published as several clips. To split an SRT file correctly, two things must happen. The subtitles are divided at the same points as the video, and the times in every part after the first are moved back so that the part starts at 00:00:00 again.
The most precise method is splitting at specific timecodes: enter the times at which the video was cut. If the exact cut points do not matter, the file can be divided into N equal parts, every N minutes or every N subtitles. Equal parts by time are measured more accurately when the video length is entered, because the last subtitle usually ends before the video does. Equal parts by number of subtitles give every part the same amount of text.
The option restart each part at 00:00 decides what the parts are for. Switch it on when the video is split too, so each subtitle part matches its own video file. Keep the original times when the video stays in one piece and the file is only divided for sharing work, for example among several translators or proofreaders. With the original times kept, the parts can be put back together later without any time calculation.
Which split method suits which task?
| Task | Split method | Times |
|---|---|---|
| Video was cut into two files at a known point | At specific timecodes | Restart each part at 00:00 |
| Film divided into equal halves, video length known | N equal parts by time, with video length | Restart each part at 00:00 |
| Long recording published as 10-minute clips | Every N minutes | Restart each part at 00:00 |
| Translation shared among several people | N equal parts by number of subtitles | Keep the original times |
| Proofreading in batches of 100 subtitles | Every N subtitles | Keep the original times |
Tips
- Not sure at which timecode to cut? Open the file together with your video in the SRT Viewer and note the time at the cut.
- Parts that kept their original times can be joined again with Subtitle Merge once the translation or review is finished.
- If a part is slightly early or late against its video clip after splitting, correct it with Subtitle Delay.
- Choose cut points in a pause between two lines of dialogue, so no subtitle sits right on the cut.

How do I split an SRT file into two parts?
Open the file and either choose two equal parts or enter the timecode where the video is cut. Both parts are listed with their time span and can be downloaded separately.
When should each part restart at 00:00?
Whenever the video is split as well. Each video file starts at zero, so the subtitles of the second and later parts must start at zero too. If the video stays in one piece, keep the original times.
What is the difference between equal parts by time and by number of subtitles?
By time, every part covers the same stretch of the video. By number of subtitles, every part contains the same number of subtitles, which is useful for sharing translation work evenly.
Why can I enter the video length?
Subtitles usually end before the video does. With the video length entered, equal parts by time are calculated on the full video, so the cut points match a video that is split into equal pieces.
Can I download all parts at once?
Yes. Each part can be downloaded on its own, and all parts together are available as one ZIP file.
Is my subtitle file uploaded?
No. Splitting runs in your browser and the file is never uploaded, so unreleased or confidential subtitles stay on your device.
