Negative moves subtitles earlier. Use this when they run consistently ahead of or behind the audio.

For subtitles that drift progressively. 25 fps material played at 23.976 needs 1.0427.

Ends each cue just before the next begins, so no two are ever on screen at once.

  • No upload The conversion runs in this tab. Your file never travels — not to us, and not to the advertising.
  • No sign-up, no email, no daily cap There is no account system to sign up to.
  • No size limit we invented Only your device's memory — about ~2 GB on a desktop browser, ~400 MB on a phone.
  • Turn your Wi-Fi off and convert anyway The conversion needs nothing but this page. Ads will not load without a connection; your file will still convert. That is the whole claim, and it takes five seconds to check.

Converts SubRip to SBV. YouTube itself accepts .srt on upload, so you usually need this only when working with the caption editor directly or with a tool that expects YouTube's own export format.

You probably do not need this

Worth saying plainly: YouTube accepts SRT, VTT, SBV and several others when you upload a caption track. If you are simply adding captions to a video, upload the .srt as it is.

SBV is the right choice when something downstream specifically expects it — an older caption workflow, a partner tool, or a script written against YouTube's export format.

What changes

Cue numbers are dropped (SBV has none), the arrow becomes a comma, and formatting tags are stripped because SBV has no markup. The timings are unchanged to the millisecond.

The timestamp is the whole difference

SRT writes 00:01:23,456 with a comma before the milliseconds and a cue number on its own line above each entry. SBV writes 0:01:23.456 with a full stop, no leading zero on the hour, no cue numbers, and a comma between the start and end times instead of an arrow. That is essentially the entire specification. The text underneath is carried across unchanged, which is why a file that looked wrong in SRT will look exactly as wrong in SBV.

Questions

Does YouTube need SBV?
No. It accepts .srt and .vtt directly. Use SBV only if something else specifically requires it.
Will my italics survive?
No. SBV has no markup, so formatting tags are removed.
Is my subtitle file uploaded?
No. The parsing and rewriting happen in this tab. Subtitle files often contain an unreleased script or a client’s content, which is a good reason not to send them to a stranger’s server. Turn your Wi-Fi off and the tool keeps working.
