Frequently Asked Questions
Is any subtitle text lost during conversion?
No! The conversion preserves all text, line breaks, and millisecond timecodes accurately.
Can I convert between SRT and VTT with 100% timing accuracy?
Yes. The converter parses every cue’s start and end timestamps down to the exact millisecond, converting commas to periods and injecting standard WEBVTT headers without timing drift.
Can converted VTT files be used directly in HTML5 video players?
Yes. Simply save the output with a .vtt extension and reference it inside an HTML5 <track kind="subtitles" src="captions.vtt" srclang="en"> tag.
