How to Add SRT to MKV Online 

Adding subtitles to MKV online is the most simple way to do that. Though these online tools are not so rich-featured, they can enable people to edit MKV files further or add some special effects. Clideo Subtitle Editor is an online subtitle editor that offers users two ways to merge subtitles with MKV.

First of all, you can upload an SRT file that contains all the contents of the subtitles you need. Then those contents can be added to your MVK video. Or you can edit the subtitles manually. This is not an easy choice, and you would spend much time typing the words and adjusting the timeline.

Therefore we strongly advise you to choose the first method, and we will show you how to add SRT to MKV.

Steps to Merge SRT with MKV Online:

Step 1. Open the page of Clideo.

Step 2. Click the "Choose file" button and import your MKV file.

Step 3. Choose the "Upload .SRT" option and find a suitable file.

Step 4. Adjust your subtitle's style, then click the "Create" button at the right bottom to export your video.



We introduced so much information about MKV subtitles editors in this post, and it's obvious that there is a common disadvantage among those tools. You cannot edit the subtitles according to your own need because you can only upload the subtitles in SRT format. 

But EaseUS Video Editor is so distinctive that it allows people to edit the subtitles easily. Download it and have a try. You will never be disappointed.
