Sometimes you need just part of a subtitle file. Maybe you're cutting a long video into shorter clips, creating highlight reels, or extracting a specific segment to translate. Whatever the reason, splitting an SRT file is a task that sounds technical but takes about 30 seconds with the right tool. Here's how to do it.

Why you can't just cut an SRT file manually

Technically you can open an SRT file in a text editor and delete the cues you don't need. But there are two problems with doing it manually:

Re-numbering. SRT files require sequential cue numbers starting from 1. If you delete the first half of a file, the remaining cues start at 347 or wherever the cut point was — not at 1. Many players will still handle this, but it's technically invalid SRT.

Timestamp adjustment for the second part. If you split a file and want to use the second part with a clip that starts at 0:00, the timestamps won't match. A cue that originally appeared at 00:22:45,000 in the full file won't appear at the right time in a clip that starts at the 22-minute mark. You'd need to shift all those timestamps back by 22 minutes.

Our Subtitle Splitter handles both of these automatically.

How to split an SRT file online (step-by-step)

Step 1: Open the Subtitle Splitter tool.

Step 2: Upload your .srt file by clicking the upload area or dragging and dropping the file.

Step 3: Enter the split point — the timestamp where you want to divide the file. For example, 00:22:30,000 to split at the 22-minute 30-second mark.

Step 4: Click Split.

Step 5: Download the two output files — Part 1 covers everything from the beginning up to your split point, and Part 2 covers everything from the split point to the end.

The tool automatically renumbers cues in both parts from 1 and (optionally) adjusts Part 2's timestamps to start from zero, so you can use it with a clip that begins at that point in the video.

When would you need to split a subtitle file?

Splitting a long video into parts. You're uploading a 90-minute video to YouTube in two parts. Your single subtitle file needs to be divided to match each upload.

Creating highlight clips. You're cutting a few minutes from a longer video for social media. You only need the subtitle cues that correspond to those minutes.

Separating season compilations. Some subtitle files combine multiple episodes. Splitting at episode boundaries gives you individual files.

Exporting segments for translation. Sending a portion of a film for translation is easier when the translator only receives the relevant subtitle segment.

Fixing a timing problem in part of a file. If the second half of a subtitle file has a sync issue (for example, after an edit was made to the video mid-way through), split the file at the problem point, fix the timing on that segment, then re-merge using the Subtitle Merger.

How to find the right split point timestamp

The split point should correspond to a moment in the video where there's a natural break — ideally a gap between subtitle cues, not mid-sentence.

To find the exact timestamp:

1. Open the video in VLC or any player
2. Pause at the point where you want to split
3. Note the exact time shown in the player (e.g., 00:22:30)
4. Open your SRT file in a text editor and find the nearest cue boundary — a blank line between two cues — closest to that time
5. Use that cue's end timestamp as your split point

Using a cue boundary rather than a mid-cue timestamp ensures no subtitle text is lost.

What happens to cues that span the split point?

If a subtitle cue starts just before your split point and ends just after it, the tool places the full cue in Part 1. No cue text is cut mid-sentence.

Splitting into more than two parts

The Subtitle Splitter divides the file into two parts per operation. For three or more parts, split iteratively:

1. Split the original file at point A → get Part 1 and Part 2+
2. Split Part 2+ at point B → get Part 2 and Part 3

After splitting: what to do next

If Part 2's timestamps need to be zeroed out (to match a video clip starting at 0:00), use the Subtitle Time Shifter to subtract the split point time from all cues in Part 2.

If you need to recombine parts later, use the Subtitle Merger with the correct time offset to put them back together.

If the split file has overlapping cues, run it through the Subtitle Overlap Fixer.

Splitting VTT files

The Subtitle Splitter works with .srt files. If you have a .vtt file, convert it to SRT first using our VTT to SRT Converter, split it, then convert back if needed.

FAQ

Will splitting damage the subtitle file? No. Splitting creates two new files from the original. The original is unchanged. The output files are clean, valid SRT with sequential cue numbering.

Can I split at a specific cue number rather than a timestamp? The tool splits by timestamp. To split at a specific cue number, open the SRT in a text editor, find the timestamp for that cue, and use that timestamp in the splitter.

Does the tool adjust timestamps for Part 2? Yes, if you enable the option. Part 2 timestamps can be offset to start from zero, making the file usable with a video clip beginning at the split point.

What if there's no subtitle cue exactly at my split point? The tool finds the nearest cue boundary. It never cuts mid-cue — each subtitle line is kept whole in either Part 1 or Part 2.

Is there a file size limit? No. Processing happens in your browser with no server upload, so there's no restriction on file size.

Can I split an SRT file to use just one part? Yes. If you only need the first 20 minutes of a subtitle file, split at the 20-minute mark and use Part 1. Part 2 can be discarded.

I split the file but Part 2 timestamps are wrong for my clip. How do I fix this? Use the Subtitle Time Shifter to adjust. If your split point was at 00:22:30, subtract 22 minutes and 30 seconds (22500 seconds = 1,350,000 milliseconds, but use the exact split timestamp for precision) from all cues in Part 2 to zero them out.
