What a .srt file is

An .srt (SubRip) is the most common subtitle file there is: a numbered list of lines, each with the time it appears and disappears. Players, TVs, YouTube and video editors all read it, which is why it is what you get when you download subtitles for a film.

Opening one to read it is another matter. Windows hands it to a video player that needs the film; Notepad shows the numbers and arrows between every line; a phone often will not open it at all; and an older file in a non-Unicode encoding shows odd symbols instead of letters. Here it is laid out as a table you can search, with the encoding recognised from the text, and any line can be corrected and the file saved back.

What you can do here

TimingShift every line, or only from a cut scene on; sync by two lines when the drift grows; convert between 25 and 23.976 fps.
TextOdd symbols instead of letters are re-read in the right encoding; hearing-impaired notes, credits and site ads come out.
Two files into oneTwo languages on screen at once, matched by time — or part 2 of a film after part 1.

Questions

Can I open it on my phone?
Yes — the page works in a phone browser the same way. Pick the file from your downloads.
Can I edit a line?
Click it: the text, the start and the end can all be changed. Clear the text to delete the line. Then save — as SRT again, or any other format.
Is the file uploaded?
No. It is read by this page on your own device; there is no server for it to go to.
