Subtitle Edit online BETA Free online subtitle translation tool introduction
Although Subtitle Edit online BETA only has an English interface, the operation is very simple. If it is just a simple translation of subtitle files, you only need to know a few functions:

First, read in the subtitle file you want to translate, open the Subtitle menu in the upper left corner, and click “Open…”:

Select the subtitle file from your computer. I’m not sure which formats are supported, but I tested SRT and it worked fine. All subtitle file formats should be fine. There is no need to adjust the Frame rate and Code page if there are no special requirements. Just press Load subtitle:

All the contents of the subtitle file will be listed on the left. You can confirm whether it is correct. If there is no problem, click the Auto translate menu above:

The translation function used by this website uses machine translation, providing Google Translate and Microsoft Translator. Which one do you like? You can also try both to see which one has the best translation quality:

I use Google translate, go to the upper left corner of the inner page and select the language you want to translate:

Then you will see that all subtitles are automatically translated into Chinese, then press OK:

The content of the subtitle file on the left has also been changed to Chinese:

Open the Subtitle menu again and click “Save/download…” to download and save it to your computer:

The format will be .srt, all original English subtitles will be replaced with Chinese, and the time will be retained:

It’s that simple! But it is machine translation after all, so some subtitles may look a little strange when translated, so just understand it yourself.
