Frequently asked questions
What changes between SRT and VTT?
VTT adds a WEBVTT header, uses a dot instead of a comma before milliseconds, and does not need cue numbers. The text and timing stay the same.
Can I use the VTT with an HTML video tag?
Yes. Add it with a track element, kind set to subtitles, and the browser shows the captions.
What is the difference between SRT and VTT?
Both list numbered lines with start and end times. SRT uses commas in times (00:01:02,500) and is the most widely supported. VTT uses dots, starts with a WEBVTT header and is the format web video players need.
What happens to ASS styling when converting to SRT?
SRT has no positions or detailed styles, so they are removed and only the text and timing remain. Italic and bold are kept where possible.
What does Text output contain?
Only the spoken lines, without numbers or times. Useful as a transcript or for translation.
Is my file uploaded?
No. Conversion runs in your browser.
Can it read files with different encodings?
UTF-8 and UTF-16 files are detected automatically. Older files in other encodings may show wrong characters; re-save them as UTF-8 first.
Does it work on phones?
Yes. It is instant on any device.
