Video Volume Booster

Increase video volume online

You don’t need to install or download anything to your computer in order to boost your video’s volume with Flixier. Our tool runs entirely in your browser, so you can just upload your video and fix the audio on any device, whether it’s a Mac, a Windows computer, a Chromebook or even an Android phone. 

Increase volume in part of a video easily

If you want to boost part of your video’s volume individually, you can use Flixier to detach the audio, cut out the part that you want to boost and then adjust the volume for that part of your audio without affecting the rest of the video. 

Boost the bass or treble in your videos 

Make bass-boosted videos easily with Flixier’s easy to use equalizer. You can choose from more than 10 presets including a bass boosted profile, or you can create your own custom equalizers and boost bass, treble or other frequencies just by dragging on the sliders that show up on the screen.

Add sound effects to your videos 

Take advantage of Flixier’s stock audio library to add copyright-free sound effects to your videos easily. Open the Audio tab, search for something that fits your video and drag it down to the timeline to add it to your video. You can trim the sound effects to make them fit and adjust the volume to make them blend in with the rest of your video.

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.
