QUICK ANSWER
Is it possible to convert TXT to SRT?
No - not a direct conversion.

SRT format needs a sequence number, a timecode range (e.g. 00:00:04,200 --> 00:00:06,800), and the subtitle text for every cue. A plain .txt file has none of the timing data, and no converter can invent timecodes that were never recorded.

Why convert TXT to SRT?

Subtitle timing comes from the audio track of a video, not from a text file. A .txt file contains only characters with no timestamps, so generating valid .srt entries from it is impossible without a synchronization source. The only real paths to an SRT are manual authoring against the video or automated speech-to-text transcription.

How to convert TXT to SRT

Subtitle Edit FREE

Open the video file in Subtitle Edit and type each subtitle line at the correct moment as the video plays. If you have a transcript in a .txt file, paste lines into Subtitle Edit and sync them to the audio manually.

Quality & what to watch

  • Renaming a .txt file to .srt only works if the file already contains properly formatted SRT content with sequence numbers and timecodes - a bare transcript produces a broken SRT that no video player can read.
  • Speech-to-text tools such as Whisper can generate an .srt directly from an audio or video file, bypassing the text file entirely.
  • YouTube and other platforms auto-generate captions from speech and allow downloading the result as an SRT file.

Frequently asked questions

Can I rename a .txt file to .srt to make it work as subtitles?
Only if the file already contains properly formatted SRT content with numbered cues and timecodes. Plain text or a bare transcript will produce a broken SRT that no video player can read.
What if my .txt file is a transcript with timestamps?
If the timestamps are in a recognized format (e.g. a YouTube-style transcript with '0:04 Hello...'), Subtitle Edit can sometimes import it via File > Import and convert it to SRT.
What is an SRT file exactly?
SRT (SubRip Text) is a plain-text subtitle format where each cue has a sequence number, a timecode range in HH:MM:SS,mmm --> HH:MM:SS,mmm format, and one or more lines of text.
