File Tools
The subtitle file that works in VLC gets rejected by your web player, and the caption file from your transcription service won't load in your editor. Different players expect different formats. These converters translate between them with timing preserved to the millisecond.
Subtitle Converter
SRT, WebVTT, and ASS with a text preview before converting, timestamp shifting in seconds, and legacy encoding repair to UTF-8.
Most Used
Make subtitles work in HTML5 video players.
Browsers only accept WebVTT in the <track> element, so the SRT file from your transcription service or download won't load on a website until it's converted. The formats are close cousins; the conversion is lossless.

ASS files carry fonts, colors, and positioning that many players and editing tools can't read. Converting to SRT strips the styling and keeps the text and timing, which is exactly what you want for uploads to YouTube or editing suites.

Timing is preserved exactly; text encoding is handled as UTF-8 so accented characters and non-Latin scripts survive the trip.

SRT, WebVTT, ASS — what each format stores and which players accept it.
Includes the practical stuff: why browsers reject SRT, what happens to ASS styling when you convert down, and how to avoid the encoding problems that turn é into é.
How to Fix Out-of-Sync Subtitles
Constant offset or growing drift? Diagnose in two checks, fix the right way.
A constant offset takes a thirty-second time shift in the browser. Drift is a framerate mismatch and needs retiming — this guide is honest about which tool does which.
