Have you created the subtitles to be added to the video or audio file, but the time codes do not match the screenplay?

Do you want to create subtitles with different font sizes and colors, but the regular notepad does not allow you to do so?

If yes, you need something more than just a text editor. Creating an SRT file is super easy because you only need a text editor and the knowledge of time codes or stamps. But when you want to edit the same and add a visual appeal, you need feature-rich editors, especially if the subtitle file has .srt format. With an SRT editor online, you can quickly finish editing the subtitles in a snap and synchronize the same with the concerned multimedia file.

As many online SRT file editors are available on the market, we have rounded up the top ten browser-based applications that can make your job easier and stress-free.
