Frequently asked questions

How do I convert SBV to SRT?
Drop your .sbv file into the converter above or tap to pick it. The file is converted instantly in your browser and the .srt download starts right away — no signup, no upload, no watermark.
Is this SBV to SRT converter really free?
Yes. The conversion runs entirely on your device, costs us nothing to serve, and is free with no file limits or accounts.
Are my subtitle files uploaded to a server?
No. The converter is 100% client-side JavaScript. Your file never leaves your computer or phone — you can even run it offline once the page has loaded.
What is the difference between SBV and SRT?
SBV (SubViewer) is the simple format YouTube offers for caption downloads: timed cues with 0:00:00.000 timestamps and no styling. SubRip (.srt) is the most widely supported subtitle format, uses comma-separated milliseconds, and numbers every cue.
Will styling and cue settings survive the conversion?
Cue text, line breaks, and timing are preserved exactly. SBV carries no styling to begin with, so nothing is lost — the result is a clean, numbered SRT file.
Does it work with Chinese, Cantonese, Japanese, or Korean subtitles?
Yes. The converter is UTF-8 native and handles CJK characters, full-width punctuation, and mixed-language files without corruption.
