Sync subtitles in your web browser

If you’ve got subtitles that are out of sync with your videos, Flixier is here to help! Our online tool makes it easy to synchronize existing subtitles with the rest of your videos easily. All you have to do is upload both files to your Flixier library and then use the visual interface to easily synchronize your subtitle with the rest of your video. On top of that, you can also use our tool to automatically translate subtitles for your video or generate brand new subtitles for your clips.

Our tool runs in your web browser, so you can access it from anywhere and fix your subtitles anywhere.

Edit and customize your subtitles

On top of allowing you to synchronize your subtitles, Flixier also allows you to edit them individually.

Online subtitle synchronizer and translator 

Make your video more accessible by adding subtitles for different languages. Flixier can automatically translate your subtitles in seconds, with over 40 languages being supported. Just select your subtitles and open the Translate tab. You can translate the same subtitle into multiple languages and then save the individual files to your computer separately.

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.
