What happens when converting TXT to SRT?

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

SRT output creates numbered subtitle blocks and uses comma-separated millisecond timestamps.

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

About TXT and SRT 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

SRT · SubRip Subtitle

SRT, short for SubRip Subtitle, is a simple, open, and highly compatible text subtitle format. It is one of the most common interchange formats used by video players, editors, and online video platforms.

File structure: An SRT file contains sequentially numbered cue blocks. Each block has an index, a start and end timestamp separated by an arrow, and one or more lines of subtitle text. Milliseconds normally use a comma separator.
Common uses: SRT is commonly used for movies, video editing imports and exports, online video uploads, and exchanging subtitle timing and text between applications.
Conversion notes: SRT primarily stores text and timing. It is not designed for complex positioning, typography, or animation, so advanced ASS or SSA styling is normally lost when converting to SRT.
