SyncMySubsConvert SBV to SRT
SBV is the caption format you get when you download subtitles from YouTube, but most video players and editing tools expect SubRip .srt. Drop your .sbv file below and it converts to SRT instantly in your browser. Nothing is uploaded, and it only ever touches the file you give it.
From YouTube captions to SRT
YouTube hands out captions as .sbv files, which store each caption as a start and end time on one line followed by the text. SubRip (.srt) is the format nearly every desktop player, subtitle editor, and video tool reads, so converting is usually the first step once you've pulled captions out of YouTube Studio. Both formats hold start and end ranges and plain text, so the conversion keeps your timing to the millisecond and leaves your words and line breaks untouched. Load your own downloaded file to convert it; this tool never reaches out to YouTube.
FAQ
What is an SBV file?
SBV is the caption format YouTube uses. When you download captions from YouTube Studio you often get a .sbv file. It stores a start and end time and the caption text, much like SRT, but with a slightly different timestamp layout and no cue numbers.
Is anything lost converting SBV to SRT?
No. Both formats carry the same thing: start and end times plus plain text. The timing is kept exactly and your text and line breaks are preserved, so the conversion is lossless.
Is my file uploaded anywhere?
No. The conversion runs in your browser with JavaScript. Your file never leaves your device and no server is involved. It only ever works on the file you choose; it does not fetch anything from YouTube.
