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.
Most subtitle fixes are small: a misheard word, a line that comes in late, a cue that should be two. Open the file here and every subtitle sits in a table you can edit directly, next to the video if you add it. Nothing is uploaded, and you can save as SRT, VTT, ASS or any other format the site writes.
Questions
How do I edit a subtitle file online?
Drop the file above, click any line to change its text or times, and download when you're done. If you always work in one format, SRT editor and VTT editor open with it ready to save.
Can I watch the video while I edit?
Yes. Add the video file and it plays next to the subtitle list, so you can check each line against the speech. The video stays on your computer.
Can I undo a change?
Yes, step by step, back to the file as you opened it.
Does it only edit SRT?
No. It opens SRT, VTT, ASS, SSA, SMI, SUB, SBV and LRC files, and saves to any of them.
