Convert Text to SRT Subtitles

How to use the TXT to SRT Converter

1. Paste your script or drop a .txt file. Separate subtitles with a blank line, or choose “One block per line”.
2. Set a reading speed (characters per second). 15 is comfortable for adults; use 12 for slower pacing or children’s content.
3. Choose a minimum duration and a maximum number of characters per cue; longer text is split at sentence or word boundaries.
4. Create the SRT, then use the two-point sync to fit the timing to your video.

How timings are generated

Without audio, a tool can only estimate when each line is spoken. Here each subtitle’s duration is its length divided by the reading speed, with a minimum duration so short lines do not flash. Cues follow each other with a short gap. This gives a plausible draft, which is good enough for slide-style videos, text-to-speech narration with constant pacing, or as a starting point for manual timing.

Splitting long lines

Text above the “max characters” value is split on sentence ends first, then on commas and spaces, so that each cue is a comfortable one or two lines. Standard guidance is no more than about 42 characters per line and two lines per cue; the default of 84 characters matches that.

Getting the timings to match real speech

1. Create the draft SRT here.
2. Play the video, find where the first and last lines are actually spoken.
3. Use the two-point sync tool to stretch the draft across the real start and end.
4. Fix individual lines in a subtitle editor if the pacing differs from a constant reading speed.

For long recordings with a transcript, a forced-alignment tool that listens to the audio will produce better timings than any estimation.

Good uses for this tool

• Scripted videos where you already have the narration text.
• Presentations, lyric slides and tutorials with consistent pacing.
• Quickly creating placeholder subtitles for a layout test.

Preparing your text for the best result

• Write in short sentences and separate each idea with a blank line; each paragraph becomes one subtitle group.
• Remove stage directions, headings and speaker names you do not want on screen.
• Put a hard line break where a two-line subtitle should break; if there is none the tool breaks automatically near the middle.
• Use consistent punctuation, because sentence-ending marks decide where long text is split.
