TXT to SRT converter
Turn a plain text script or transcript into a SubRip (.srt) subtitle file. Each line becomes one subtitle; timestamps in the text are used when they are there.
Move subtitles by a fixed amount when every line is off by the same delay.
Seconds (2.5), milliseconds (1500ms) or a time (00:00:02,500). Subtitles appear too early → Later.
For subtitles that drift. Pick two cues far apart and enter when each should appear.
Rescale times when the subtitle was made for a video with a different frame rate.
The file open now is part 1 / language 1.

How to convert TXT to SRT
- Open the TXT file. Click Open subtitle file or drop your .txt file onto the tool. You can also paste the text.
- Choose SRT. “SubRip (.srt)” is preselected in the Save as menu.
- Fix anything else (optional). Shift or sync the timing, repair the encoding or clean up overlaps before saving.
- Download. Click Download to save the .srt file in UTF-8, or Copy to paste it elsewhere.
What changes when you convert TXT to SRT
Without timestamps, every non-empty line becomes a cue that lasts as long as it takes to read — about 15 characters per second, between 1.2 and 7 seconds — with a short gap before the next one. You then line the result up with the video using Shift, Sync or the editor’s “Start = video” buttons.
Lines that start with a timestamp in brackets, such as [00:01:02] Hello, or a time on its own line followed by text (the layout of many copied transcripts), start at that time. Each cue ends at the next timestamp or after its reading time, whichever comes first.
Keep each line short — two subtitle lines of up to about 42 characters is a common limit. Split long sentences in the text before converting, or edit them afterwards in the cue editor.

[waves crashing] MARA: You kept the lamp burning all night again. Someone has to. The fog came in early. The ships don't need us anymore. They have satellites. Satellites don't see the rocks the way I do.

FAQ
How do I make an SRT file from a text file?
Open or paste the text here, keep SRT as the output and download. Then load the video and adjust times with the editor or the Sync tab.
Can I paste a YouTube transcript?
Yes. Transcripts with a time on its own line (0:04) followed by the text are recognized, and every line starts at its timestamp.
Are my subtitle and video files uploaded?
