Turn a line-by-line transcript into an SRT file

Paste a transcript with one caption per line, then choose how long each line should stay on screen. This creates a clean, evenly timed SRT file for slides, quote videos, drafts, and workflows where exact speech synchronization is not required.

Timing for every line

This makes evenly timed cues. It does not synchronize text to speech.

FAQ

How does text become an SRT file?

Each non-empty line becomes one numbered subtitle cue. The first cue begins at your chosen start time; every following cue uses the same display duration and optional gap.

Will the captions match spoken audio automatically?

No. This converter creates predictable, evenly spaced timing and does not listen to audio. Use the SubtitleRocket editor when captions need to follow real speech.

What should I put on each line?

Put one short, readable caption on each line. Empty lines are ignored. For social video, a compact phrase is usually easier to read than a full sentence.

Does the transcript leave my device?

No. Cue creation and the SRT download happen entirely in your browser.

Need the captions on the video itself?

These utilities handle subtitle files. To generate captions from speech, style them, and burn them into an MP4, open the full editor; free 720p export, no signup to start.
