Add subtitle to MKV online
Making a video more accessible for people with disabilities or for anyone that can’t watch with sound on is a must these days. Videos are being watched in all sorts of environments and making them easier to see will ensure you get as many views and engagement as possible.
With our video tool you can add subtitles to MKV videos directly from your browser. We make this task super fast and help you avoid complicated video editing software that requires a powerful computer to run. You don’t even have to download or install any software.
Add SRT to MKV
Among other files Flixier supports one of the most popular subtitle file types available, you can add SRT subtitles to MKV videos without any conversions or other complex processes. Simply add your video and subtitle on top of eachother in Flixier and you’re done.
Merge Subtitles with MKV online
One of the biggest advantages of Flixier is that you can use it to merge subtitles with MKV online. No more software downloads and installs, this means that your computer will run clean without any useless software that will take up resources. Just fire up your browser and head over to Flixier whenever you need to add subtitles to a video.
Automatically add subtitles to MKV
Another way to dramatically reduce the time needed to add subtitles to a video is our auto subtitle generation feature. Simply add a MKV file to the Flixier timeline and click the Generate auto subtitle button. The video will be processed super fast and the subtitle will be added to it.
Making subtitles stand out and easy to read is a must. To help you make this happen we let you change the subtitle font, size, color and to even add a background. You can also change the subtitle size and position. These changes should be subtle though, usually subtitles don’t go overboard with customization to not interfere with the video itself.
The easiest way to get started is by clicking the Choose Video button above, you can select videos and subtitle files from your computer or use our direct integrations with cloud storage services to import videos in seconds.
Now drag and drop the MKV video on the timeline at the bottom of the screen and the SRT subtitle file on a track on top of it. Make sure that the files are aligned to the left to avoid any synchronization issues.
At this step you can also change the subtitle font, color size or add a background color. All this is optional and you can skip straight to the last step.
When happy with the result simply press the Export button at the top right of the screen and then the Export and Download button. That’s it, you're done. The video will be processed by our super fast cloud servers and it will download automatically to your computer when ready.

I’ve been looking for a solution like Flixier for years. Now that my virtual team and I can edit projects together on the cloud with Flixier, it tripled my company’s video output! Super easy to use and unbelievably quick exports.
My main criteria for an editor was that the interface is familiar and most importantly that the renders were in the cloud and super fast. Flixier more than delivered in both. I've now been using it daily to edit Facebook videos for my 1M follower page.
I'm so relieved I found Flixier. I have a YouTube channel with over 700k subscribers and Flixier allows me to collaborate seamlessly with my team, they can work from any device at any time plus, renders are cloud powered and super super fast on any computer.
