FixMySubs.com is the easiest way to fix your movie subtitle synchronization issues. All you have to do is upload your subtitle file (.srt, or .sub) and then on the next screen match three of four random subtitle text with their actual time (by watching the video). Our site will then fix your subtitle file by comparing the difference in the time you specify with the one in the subtitle file and give you a perfectly synced subtitle file for watching your movie.
