How to convert SBV to SRT
- Paste your SBV subtitles into the SBV source box, or choose a .sbv file (UTF-8, up to 5 MiB) — conversion runs automatically.
- Leave a blank line between subtitle cues. Use Load sample for an example of the required layout.
- Edit the source any time to re-convert, or press Convert to retry on demand.
- Review the SRT result — cues are numbered sequentially, and any warnings appear with the output.
- Download the .srt file, or copy the text straight out of the result box.
What changes between SBV and SRT
SBV (SubViewer, .sbv — a format long associated with YouTube caption uploads) writes each cue as one timing line, 0:00:01.000,0:00:03.000, followed by the caption text; there are no cue numbers and the separator between start and end is a comma. SRT numbers every cue and writes 00:00:01,000 --> 00:00:03,000 with a --> arrow and comma decimals. This converter adds the cue numbers and rewrites the timestamps; cue times and caption text are preserved.
Frequently asked questions
What is an SBV file?
SBV is the SubViewer subtitle format, best known as a caption format accepted by YouTube. Each cue is a start,end timing line with dot-millisecond timestamps followed by the caption text.
Do my timings change?
No. The same start and end times are kept; only the notation changes to SRT's numbered-cue, comma-decimal form.
Are my subtitles uploaded anywhere?
No. Parsing and conversion run entirely in your browser with JavaScript. Nothing is sent to a server, stored, or logged.
What files can I load?
A UTF-8 text file up to 5 MiB. You can also paste subtitle text directly into the source box instead of choosing a file.
