How do I convert plain text to SRT subtitles?+
Paste your script or upload one or more .txt files. Pick how text is split into cues (paragraph, line, or sentence) and set a speaking pace in words per minute. Copy the SRT output or download a .srt file. Uploaded batches can be exported individually or as a ZIP archive.
Is this TXT to SRT converter free?+
Yes. This tool is completely free with no account, card, watermark, or desktop software install required.
Is my script uploaded to a server?+
No. Splitting, timing, and SRT formatting run locally in your browser. Your text files and exported subtitles are not sent to Vidsembly or any third-party server.
How are subtitle timestamps calculated?+
Each cue duration is estimated from its word count and your chosen speaking pace (words per minute), with minimum and maximum on-screen times applied. Add a start offset if your video begins after zero. Fine-tune timing in Premiere, DaVinci Resolve, Descript, or YouTube Studio after export.
Which split mode should I use?+
Paragraph works for narration scripts with natural breaks. Line fits poetry, shot lists, or one line per slide. Sentence creates shorter cues that read well on social clips and tutorials. You can regenerate SRT with a different mode without retyping your script.
Can I control line length in each subtitle cue?+
Yes. Set max characters per line to soft-wrap long cues into two lines, similar to common broadcast caption limits. Adjust the value if your player or platform recommends a different width.
Can I convert multiple text files at once?+
Yes. Upload several .txt files in one session. Each file is converted with the same timing options, and you can download SRT files individually or together in a ZIP.
