Why add subtitles to your videos online with Flixier?

Make your videos more accessible

Subtitles and captions are essential to ensure that your videos can be watched and enjoyed even by hearing impaired individuals.

Share videos on social media

The vast majority of people watch Facebook or Instagram videos muted, since they usually do it on their phone, while in public. Subtitles ensure that these people can still understand the message you’re trying to convey in your videos.

Expand your audience to new regions

Having subtitles in a different language than the one that’s being spoken on camera can help you expand your audience to different regions!

Get the job done fast

Because Flixier works in your browser and does all the hard work in the cloud, your videos will always be ready in 3 minutes or less. It doesn’t matter if you’re using a brand new Mac, a Windows laptop or a Chromebook!

Customize your subtitles quickly with presets

Choose one of our subtitle presets and apply it to your subtitles with one click. This is an easy way to make your subtitles look better and more legible. You're still free to customize the fonts, size and color of your subtitles afterwards.

Synchronize subtitles easily

It’s easy to synchronize subtitles using Flixier! Just drag with your mouse button in the timeline to modify the timings and make sure that the audio and text are in sync! 


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.

Steve Mastroianni -

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.

Evgeni Kogan

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.
