SRT Merger

Merge multiple subtitle files into one clean SRT. Keep original timing and sort by timestamp, or append files one after another for multi-part videos.

Upload subtitle files
Add two or more SRT files. VTT, ASS, and SSA inputs are accepted and exported as SRT.

Merge mode

Append mode is best for part 1 + part 2 videos. Sort mode is best when all files already use the same timeline.

Use seconds. Example: 1.5 adds a small pause between files.

Output: 0 SRT cues

Merge SRT files for multi-part videos

Use the SRT merger when your subtitles are split across several files or when you need one subtitle track for a combined video. The output is a standard SRT file that works in common players and editors.

Merge many files

Drop multiple subtitle files and combine them into a single SubRip file.

Control the order

Append files sequentially for split videos, or preserve original times and sort by timestamp.

Private browser workflow

The merge runs locally in your browser, so subtitle files stay on your device.

SRT merge examples, file order, and timing choices

Use an SRT merger when subtitle cues are split across multiple files and you need one subtitle track. It is especially useful after joining video parts or when subtitle exports arrive in separate chapters.

Example input and output

Part 1 input
1 00:00:01,000 --> 00:00:03,000 Opening line.
Merged output
1 00:00:01,000 --> 00:00:03,000 Opening line. 2 00:10:04,000 --> 00:10:07,000 Next part starts here.

Best for

Joined video files

Append subtitles from part 1 and part 2 so they match a newly combined video.

Chapter exports

Combine separate subtitle chapter files into one continuous SRT track.

Timeline cleanup

Keep original timestamps and sort all cues when the files already use the same timeline.

Common file issues handled

Append mode

Each file is shifted after the previous file, with an optional gap in seconds.

Sort mode

Original timestamps are preserved and all cues are ordered by start time.

Cue renumbering

The exported SRT is renumbered from 1 so players and editors can read it cleanly.

Local processing

The merge happens in your browser; subtitle text is not uploaded to a server.

Frequently Asked Questions

Can I merge multiple SRT files into one file?
Yes. Add two or more subtitle files, choose append mode or timestamp sort mode, then download one merged SRT file.
What is append mode?
Append mode places each file after the previous file. It is useful when subtitles belong to part 1, part 2, and part 3 of the same video.
What is sort by original time mode?
Sort mode keeps each cue's original timestamps and orders all cues by start time. Use it when all files already share the same timeline.
Are my subtitle files uploaded?
No. Files are parsed and merged locally in your browser after the page loads.
