If you already have transcript text, you are most of the way there. The remaining work is to split the text into readable captions, add precise timestamps, and save everything in the small but picky SRT format.
This guide shows how to make SRT subtitles from a transcript, what a valid cue looks like, and which free subtitle tools help when you need to convert, clean, or extract caption text.
What An SRT File Needs
An SRT file is plain text. Each subtitle cue has a number, a timestamp range, one or two lines of caption text, and a blank line before the next cue.

How To Make SRT Subtitles
- Start with a clean transcript. Remove filler that should not appear on screen, fix names, and break long paragraphs into natural speech chunks.
- Split text into caption-sized cues. Keep each cue short enough to read comfortably. One sentence or a short phrase usually works better than a dense paragraph.
- Add start and end times. Match each cue to the moment the speaker begins and finishes. SRT timestamps use commas for milliseconds.
- Number the cues in order. Start at 1 and increase by one for every caption block.
- Save as plain text with a .srt extension. Use UTF-8 text when your subtitles include accented names, symbols, or multiple languages.
- Preview before publishing. Upload the SRT file to your video platform or editor and watch for timing drift, missing line breaks, and captions that disappear too quickly.
Create Subtitles From Transcript Text
When you need to create subtitles from transcript text, the fastest path is to paste the transcript into the TXT to SRT Converter. It gives you a structured SRT starting point that you can adjust against the video.

- Use timestamp ranges like 00:00:01,000 --> 00:00:04,200.
- Keep a blank line between cues.
- Keep captions readable on mobile and TV screens.
- Avoid overlapping timestamps unless your platform expects them.
- Check names, product terms, and punctuation before upload.
