MP3 Joiner

Use a simple MP3 combiner

Flixier is easy to use and allows anyone to combine and merge MP3 files right in their browser. Everything can be done via dragging and dropping and the interface is clearly labeled to make it easy for newcomers to find the options they need, while still remaining familiar to anyone who has used editing software before.

Cut, trim and edit your MP3 files

Use our powerful editing features to cut out unwanted parts from your MP3. Drag on the ends of an MP3 file in the timeline to trim its duration. Use the right hand menu to add a fade-in or fade-out transition to the audio, pan it from left to right, or use the Equalizer which comes with a number of useful presets as well as the option to customize it yourself.

Merge MP3 from different sources

Bring MP3 files over from your computer, SoundCloud or cloud storage platforms like Google Drive. Flixier offers plenty of import options so you can always reach your files. You can even use audio from YouTube videos by copying and pasting the link into the import menu. If that’s not enough, we also offer a huge library of free stock music that you can use in your projects. 

Mix multiple audio files together 

Use the multi-track timeline to combine multiple audio tracks together. Add each file to its own track, sync them together by dragging them around on the timeline and adjust their individual volume to make sure that your final project sounds balanced and right.

To combine your MP3 files, drag them over from the library down to the timeline and arrange them in the desired order. For YouTube or TikTok videos, you’ll need to add them to the timeline, right click on them and select Detach Audio, to extract the audio.

To make two files play at the same time, simply place them on different tracks.

You can select a file and use the right side menu to adjust its volume, pan the audio to make it sound like it's coming from the left or right side, apply fade-ins or an equalizer.

Download your creation

When you’re done combining your MP3 files, click the Extract button in the top right corner of the screen. In the Save File As menu, make sure to select Audio and then click on Export and Download. Flixier will take a couple of minutes to process your audio and then it will be saved to your computer in MP3 format.

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.
