This page opens the subtitle timing fixer with WebVTT chosen as the output. The cues keep their text and times; the file gets the WEBVTT header, and the comma in each time code becomes a dot, which is what web video players expect.
If the subtitles run early or late, set a shift before you download, or use two known lines to sync the whole file. Fix subtitle timing covers every timing option.
How to fix subtitle timing
- Paste the SRT or WebVTT text, or drop the file onto the box.
- Shift the cues, or sync two cues to the times they should start at.
- Copy the result, or download it as an SRT or WebVTT file.
Questions
What is the difference between SRT and VTT?
Both list numbered cues with start and end times. WebVTT starts with a WEBVTT line, uses a dot before the milliseconds and can carry cue settings; HTML5 video players read WebVTT through the track element.
Will my line breaks and italics survive?
Line breaks are kept. Tags such as <i> are stripped by default; untick Strip tags to keep them, since WebVTT players understand simple italic and bold tags.
How do I fix subtitles that drift?
Find two cues, one near the start and one near the end. Enter their cue numbers and the times they should start at. Every cue in between moves onto the same straight line.
What does the frame-rate change do?
It scales every time by the first rate divided by the second. Use it when subtitles were timed for one frame rate, like 23.976, and the video plays at another, like 25.
Is my subtitle file uploaded?
No. The text is read and rewritten in your browser, so the file never leaves your device.
Can it convert SRT to WebVTT?
Yes. Choose WebVTT under Save as. The times then use dots and the file starts with the WEBVTT line.
