What happens when converting TXT to VTT?

Plain Text content is parsed into a unified millisecond timeline before being exported as WebVTT. Valid timing and subtitle text are preserved.

WebVTT output uses dot-separated millisecond timestamps and includes the WEBVTT file header.

TXT has no timeline, so every non-empty text line is assigned five seconds by default.

About TXT and VTT subtitle formats

Learn what each file format is, how it is structured, where it is commonly used, and what to consider during conversion.

Source file format

TXT · Plain Text

TXT is a plain-text file rather than a dedicated subtitle format with a standardized timeline. It usually stores subtitle, dialogue, or lyric text without information about when each line appears.

File structure: TXT has no fixed subtitle syntax and generally contains one or more lines of text. Individual files may include paragraphs, speaker names, or other manually arranged information.
Common uses: TXT is commonly used for video transcripts, dialogue editing, translation and proofreading, lyric extraction, and passing subtitle content to text-processing or AI tools.
Conversion notes: Exporting to TXT removes every timestamp. When converting TXT to a timed subtitle format, this tool treats each non-empty line as one cue and assigns it five seconds by default.

Target file format

VTT · WebVTT

VTT, or WebVTT, is a timed-text format designed for web video. HTML5 video elements can use it through track elements for subtitles, captions, chapters, and other synchronized text.

File structure: A WebVTT file normally begins with a WEBVTT header and uses a dot as the millisecond separator. It may also contain cue identifiers, positioning settings, comments, and metadata.
Common uses: VTT is commonly used by web players, online courses, recorded streams, accessible closed captions, and videos that need subtitles displayed directly by modern browsers.
Conversion notes: VTT supports richer web-caption features than SRT. Cue positioning, voice tags, chapters, and some metadata may not survive conversion to simpler formats.
