Subtitle Merger
Merge several subtitle files into one, in sequence or with a custom offset.
Combine split subtitles into one file
Older movie releases are often split into CD1 and CD2, with separate subtitle files. If you joined the video into one file, the subtitles need joining too. The Subtitle Merger does it automatically.
Timing options
Each following file can start where the previous file's last subtitle ends, or be added with a custom offset you set. That way the second part's subtitles start at the right moment, whatever the length of the first part.
Format flexibility
Mix SRT, VTT, ASS, SSA and TXT inputs and save the result as SRT or VTT. Merging happens in your browser.
How to use Subtitle Merger
- Choose the subtitle files in the right order.
- Set the placement or offset for each file.
- Choose the output format (SRT or VTT).
- Download the merged subtitles.
Why use this tool?
No more copying subtitles by hand and recalculating every line's time; numbering is fixed automatically.
