Just click on Get Started to open Flixier in your web browser, upload your MP4 videos and then merge them together using our precise and powerful timeline. You can even add music in order to create montages and choose from a large library of free transitions that you can add to your videos.
You don’t need any editing experience for this. Our interface is intuitive and easy to figure out on your own, so you won’t have to waste hours watching video tutorials in order to merge your MP4s.
Join MP4 videos for free

All the video merging and editing features are available to free users, so you just need to click on Get Started and start uploading your videos to Flixier in order to experience the speed and convenience of an online video editor.
Combine and edit multiple MP4 files
Take advantage of our powerful and intuitive timeline system to combine multiple files together easily. Arrange them in the order you want by dragging and dropping. Use the Cut button to get rid of unwanted parts and drag on the ends of a clip to trim it. Use the controls on the canvas to resize videos and combine them in interesting ways such as picture-in-picture or split screen effects.
Use transitions when joining MP4 files together
Overlay two videos on the same track and use the drop-down list to choose from a large number of free transitions which you can add to your videos. You can drag on them in the timeline to modify their duration or use the menu on the right side of the screen to enter the duration manually for more control.
Combine MP4 files together in minutes
Merge MP4 files together in minutes, with Flixier. Our tool uses cloud powered servers to process your videos in order to ensure that they’ll always be ready in 2 minutes or less, regardless of your system specifications. Turn any computer into a video editing workstation with Flixier.
How to merge MP4 files
Click on Get Started to open Flixier up in your browser. You can upload the videos from your computer, copy and paste a YouTube link or bring them over from cloud storage services like Google Drive, Dropbox or OneDrive.
Combine your MP4 files by dragging them from the library down to the timeline. Move them around on the timeline to order them however you want and drag on the ends of a clip to trim it. You can also overlap two clips on the timeline to choose a transition that you can add between them.
When you’re done combining your MP4 files, click the Export and Download button in the top right corner. Flixier will take a few minutes to process your video and then it will be saved to your computer.

You can even use Flixier to combine GIFs together into a longer GIF or save them as an MP4 file.
Have full control over the audio
If your videos have audio, you can right click on it and select Detach Audio to edit it on a separate track. You can also fade audio in and out and use the volume slider and equalizer to make sure the audio is just right after you merge your MP4 videos together.
Combine MP4 videos for social media
Merge videos together and publish them on your social media. Whether it’s a YouTube video, a TikTok or an Instagram story, Flixier makes it easy to resize your video in order to optimize it for the right platform. If you want to save time, you can even give your videos a title and description and publish them to YouTube, TikTok or Facebook straight from the Export menu.
What people say about Flixier
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.
