Read as — change it
The file opens again in the encoding you choose.
Undo your changes first: reading the file another way opens it again.
A .sub file stores times as frame numbers, so it has no meaning without a rate. We don't guess one.
Click any line to change its words or times. Times read as 00:01:02,500, 00:01:02.500, 1:02.5 or 62.5 seconds. Press Enter in a time, or Ctrl+Enter in the words, to keep a change; Escape puts the line back.
Plays on your computer; it is never uploaded.
No subtitles left. Add one at the start to begin again.
Every subtitle sits in its own row with its start and end time, so you edit the words without breaking the numbering or the time lines, which is the usual risk with Notepad. Add the video and it plays beside the list, so you can check each line against the speech. Undo works step by step back to the file you opened. Nothing is uploaded.
Questions
How do I edit an SRT file online?
Drop the .srt above. Click a line to change its words or times, then save.
Can I shift all the times at once?
For a whole-file shift, Shift subtitle timing is quicker: one number moves every line.
Can it save in another format?
Yes. SRT is selected first, and VTT, ASS and the others are a click away.
