How to convert TXT to SRT
- Paste your text in the left box, or click Open file to load a
.txt. - Choose how to time it: by reading speed (15 characters per second is a good default), a fixed number of seconds per subtitle, or spread over your video length.
- Check the result on the right, then click Download SRT. Optional: load your video below to preview the subtitles on it.
How the text is split
- Each line of your text becomes one subtitle (or choose by sentence for running text).
- Long lines are wrapped at 42 characters and two lines per subtitle — the usual limits of streaming platforms. Both values can be changed.
- If your text already has timestamps —
0:05 Hello,[00:01:02] Hior a YouTube transcript with times on their own lines — those times are used.
Getting the timing right
Automatic timing gives every subtitle a reading time between 1 and 7 seconds. That works for narration, lectures and slideshows. For speech that must match the voice exactly, use the SRT maker: play your video and tap a key when each line starts.
Frequently asked questions
What is an SRT file?
SRT (SubRip) is the most widely supported subtitle format: a plain text file with a number, a time range like 00:00:01,000 --> 00:00:03,500 and the text for each subtitle. YouTube, Vimeo, VLC, Premiere Pro, DaVinci Resolve and most TVs read it.
Can I convert a transcript with timestamps?
Yes. Lines that start with a time (0:05, 01:02:03, [00:12]) are detected and kept; each subtitle lasts until the next timestamp. See also transcript to SRT.
How do I make the subtitles match my video length?
Choose Spread over and type the video length (for example 00:04:30), or load the video below — its length is filled in for you.
Accented or Cyrillic letters look garbled. How do I fix it?
The file uses an old encoding. Pick the right one in the Encoding menu under the input (for example Windows-1251 for Russian, Windows-1250 for Central European, Windows-1252 for Western languages). The output is always saved as UTF-8.
Are my files uploaded?
No. Text, subtitle files and videos are processed by your browser on your own computer. Nothing is sent to a server.
Is it free? Is there a limit?
Free, no sign-up, no watermark. Files up to 30 MB of text work instantly — that is far more than any subtitle file.
