6 Best MP4 Mergers to Join Videos Easily

Not all software allows you to combine videos in the MP4 format. And even if they do, the quality you get is not satisfying. The reason is pretty basic – overrated and underrated video merging software. Some tools are complicated, while others are extremely user-friendly with the interface and options.

So, after spending several days on the research, finally, here are the 6 best mp4 mergers along with their tutorials to help you understand the process and complexity of each software and pick the best one in terms of simplicity and user-friendliness. 

Part 1: Free Video Joiner (For Windows Users Only)

Free Video Joiner is a free tool to use for Windows users. You can join multiple videos to turn into a big video file. The software allows you to convert WMV, MPG, MPEG, AVI, and MOV files into MP4, MOV, WMV, and AVI. You can also “Save As” videos in VCD and DVD, iPhone, iPod, Zune, or PSP video formats.

The company claims “no quality loss” when the complete video is out. However, you have to be very picky when selecting the first video in your list to merge with others because the Free Video Joiner keeps the same width and height of the merged file as of the first video.

So, for instance, if you have 10 videos in the list to merge in the MP4 format, the first video has 1280 x 720 dimensions while the rest are 1920 x 1080. Then, the final merged video will be available to you in the same width and height as the first video (1280 x 720).

Merging Videos in Free Video Joiner

Step1: Download Free Video Joiner

Open your browser and go to the Free Video Joiner website. Then, click the “Download” button on the page to save the setup on your computer.


Step 2: Install and Run Free Video Joiner

Now, double-click on the Free Video Joiner set up to install it in your system. It will hardly take a few seconds for the entire software to get into your system’s hard drive.

Once the software is installed, open the software, and you will see the interface like this.


Step 3: Add Files

Click on the “Add Files” button.


And select the clips you want to merge in MP4.


To change the order of the videos, you can use the “Move Up” or “Move Down” button.


Step 4: Select Output Folder

Choose your output directory to save the merged file by clicking on the “Select” button.


Then, click on the “Video” tab to choose the format of your joined video. Also, take your time to choose the “Presets” from the drop-down menu below the video tab.

As you can see, MP4 is selected in the screenshot below.


Step 5: Staring Merging in MP4

Now, click on the “Join Now” button.


You will see that the “Overall Progress” bar will begin to increase.


Once the bar is 100%, click on the “Open Folder” button to directly visit the folder where you will find the merged video. Or click the “Finish” button if you wish to start another project.


Part 2: Freemake Video Converter (For Windows Users Only)

Freemake Video Converter is reliable software to convert videos without registration. The program is free to download with more than 180 million users worldwide. And not just the MP4, but you can convert videos in all the popular formats and use the program to copy and burn DVDs.

Apart from the video conversion feature, you can use Freemake to merge your MP4 videos from your Windows operating system. However, the software is unavailable for MAC users, and it is one of the major drawbacks of this video merger.

Merging Videos in Freemake Video Converter

Step 1: Download Freemake Video Converter

First, go to the Freemake Video Converter website and click on the “Free Download” button.


Then, install the software on your computer and open it. The software appears to be simple like this.


Step 2: Add Videos

Click on the “Video” tab from the top menu to select videos you want to merge.


As you can see below, two videos are uploaded on the software.


Step 3: Rearrange Video Order

If you wish to rearrange the videos, you can do it by simply dragging the video up or down with the help of your mouse.


For example, the “Photo Slideshow” video, which was previously on the top, is now placed beneath the “Intro” video.


That means the merged video will begin from the “Intro” video, and then the “Photo Slideshow” will continue right after the first clip ends. All be done without any break or pause.

Step 4: Join Videos

After rearranging the videos, use your mouse to select clips by clicking once on each video. All selected videos will be highlighted in the “light blue” color.


Then, take the mouse cursor on the top-right side of the software and turn on the “Join Files” button by clicking on it.


You will see that a merged video will be added to the software.

For instance, you can see that a new file has been added to the interface, showing the number of merged files in the red circle.


The above screenshot represents a single merged video that includes two files.

Step 5: Choose Your Output Video Format

Look at the bottom of the software to see different video formats, and click on “MP4.”


Click on the “Preset” menu to choose the format and size of the output video. Then, select the output folder.


Step 6: Save Your Video

Lastly, click on the “Convert” button to allow the software to merge the video in MP4 format and save it on your computer.


Part 3: Boilsoft Video Joiner (For Windows and MAC Users)

Boilsoft Video Joiner is a video merger tool to join MP4, WMA, WMV, ASF, 3GP, RMVB/RM, MPG, MPEG, AVI, VOB, FLV, and MKV clips into one complete single video. You can download the free trial version or buy the full software for your MAC and Windows operating systems.

Boilsoft Video Joiner also offers Encode mode and Direct Stream mode, allowing you to merge clips efficiently into different formats at great speed.

Merging Videos in Boilsoft Video Joiner

Step 1: Download and Install Boilsoft Video Joiner

Visit the Boilsoft Video Joiner website from your computer browser and click on the “Download” tab.


If you want to install the software on Windows OS, then click on the “Windows” tab and then click on the “Download” button next to the “Boilsoft Video Joiner” software.


Contrarily, you can download the program for MAC operating system by clicking on the “Mac” tab and clicking the “Download” button.


Now, run the installer to install the software on your computer and open it.


Note: The screenshots are from the previous version of Boilsoft Video Joiner. However, this tutorial's steps to merge MP4 videos are workable on the latest version.

Step 2: Add Videos in Boilsoft Video Joiner

Click on the “Add File” icon on the top menu to add the clips you want to join together.


Here you can see that two files have been uploaded. Plus, with the small green “arrow” buttons, you can rearrange the order of the clips.


Step 3: Merge Videos

Find the “Merge” option on the top menu, and click it.


Then, choose the “Direct Stream” mode or “Encode Mode” from the merge mode options, and click on the “OK” button.


Note: It is suggested to choose the “Direct Stream” mode if you want files to be converted in the MP4 format.

Step 4: Save Joined Video

After clicking the “OK” button, choose the folder to save the merged video on your computer. And click the “Save” button.


A green progress bar will start until you see the “Finished” message above the bar, confirming that the video has been merged. So, click the “Open Folder” button to see the joined video in MP4 format.


Part 4: Media Cope (For Windows Users Only)

Media Cope is free software with multiple features, including audio and video joiner. The software is available for Windows users only but does not support the latest Windows versions. So, if you are running XP, Vista, Windows 7, or Windows 8, you can easily install the software on your computer.

Although the software doesn’t support MAC, you can still join and save the videos on your iPhone. Nevertheless, the developers assure that the software supports all major formats, such as MP4, MOV, 3GP, AC3, AMR, WAV, MKV, FLV, DIVX, AVI, and many more.

Merging Videos in Media Cope

Step 1: Download and Install Media Cope

Downloading Media Cope is no big deal. All you need to do is go to the official Media Cope’s website and click on the “Download” tab on the top menu.


Once you are taken to another page, click on the “Download” button to save the setup on your computer.


Double click the “MediaCopeSetup.exe” file to install the software. It will only take a few minutes to install the complete program on your PC.

So, after installing Media Cope, open the program, and you will see a blank screen with several options on the top and bottom of the interface.


Step 2: Add Files

Click on the “Audio/Video Joiner” tab to select your video clips.


Select your clips and click on the “Add” button to transfer files on the software.


As you can see, two video files are added to the platform.


Step 3: Choose Output Format

If you look down in the software, you will find the “Output Format” options. So, choose your format (MP4 recommended) and select the video quality from the drop-down menu.


Step 4: Merge Videos and Save

Now, click on the “Join” button, choose your output folder, and give time to complete the process.


After the process ends, enjoy your merged video in the output folder.

Part 5: MP4Joiner by MP4Tools (For Windows, MAC, and Linux Users)

MP4Joiner is a free software to join MP4 format videos into one single video that comes with an MP4Splitter. This software duo is called MP4Tools. So don’t get confused by the name when downloading the program on your PC.

A good thing about MP4Joiner is that it is developed for multiple platforms, such as Windows, MAC, and Linux. But unfortunately, it only supports “win32,” “Mac 10.10 and Catalina,” and “BZ2” file extension.

Merging Videos in MP4Joiner

Step 1: Download MP4Joiner

The first step requires downloading MP4Joiner on your computer according to your operating system. To do that, go to the MP4Joiner’s site. And click on any one of the following “.exe” files to download the setup.


Then, install the program in your Windows, MAC, or Linux, and run it. The interface is extremely simple, with no confusing options.


Step 2: Add Files in MP4Joiner

Next, click on the “Add Video” tab with a green “+” sign.


Doing so will help you choose videos you want to join together. So, select the videos and click on the “Open” button, as shown in the screenshot below.


Step 3: Start Joining Videos

Once all your selected videos are imported on the interface, click on the “Join” tab.


Then, choose the folder where you want the merged video to be saved, and click the “Save” button.


A new window will appear, showing a green progress bar.


Wait until you see the “Successful” note on the top of the progress bar, and then click on the “Close” button.


Go to your output folder to watch the joined video in the MP4 format.

Part 6: Filmora by Wondershare (For Windows and MAC Users - Recommended)

Filmora Video Editor is one of the famous video editing software by Wondershare. It is like a gateway to creativity for beginner and experienced editors. The software offers a wide range of tools and presets, which makes video editing quick and easy.

Gladly, Filmora can help you merge your videos without destroying a pixel in any format of your choice, including MP4. Also, the process is pretty simple, time-saving, and fun. Furthermore, you can also include flavors to your video merger by adding several transitions and effects to your videos.

Free Download

Merging Videos in MP4Joiner

Step 1: Download Filmora by Wondershare

Enter Filmora’s website in your browser to visit the homepage and click on the blue “Free Download” button.


After downloading the setup, install the software on your device. The process will only take a few minutes. Then, open Filmora, and you will see a modern-designed interface with all the tools and presets right in front of your eyes.


Step 2: Import Videos You Want to Merge

Use your mouse to click the blue “+” icon in the center of the software to import videos from your computer.


Then, drag-and-drop the videos to your timeline. But make sure that you place both clips on the same timeline. As you can see below, there are two clips. The first clip is named “Travel 05,” while the second video is called “Travel 06.”


Step 3: Fill the Gap to Merge

When you will drag-and-drop videos on the timeline, the chances are that there will be a gap or a blank space between the two clips, like this.


If this blank space is left untreated, the merged video will include this empty black space, as you can see on the preview screen.


Therefore, use your right mouse click to hold the second video and drag it to the wall of the first video without leaving any gap in between both clips.


Great! You have already merged the videos. Now, let’s move on to the final step.

Step 4: Export the Joined Video and Save in MP4

Click on the “Export” option on the left of the preview screen to see the settings window.


Under the “Local” tab, select “MP4” and feel free to perform other changes, such as choosing an output folder, renaming the merged video, picking the resolution, and more. Once you are satisfied with the settings, click on the “Export” button (on the right bottom of the screen) to save the video on your computer.


And it’s done!

Bottom Line

Among the 6 best MP4 mergers, Filmora seems to be winning. It’s not just a video editor with plenty of tools, but you can also join two or more videos in MP4 format without sacrificing the video quality.

On the other hand, video merges like Free Video Joiner, Freemake, Media Cope, Boilsoft Video Joiner, and MP4 Joiner have limited options. Plus, they are time-consuming, and some of them even disturb the video and audio quality when clips are merged through them.


Q1. What is the best video merger for MP4?

There are many excellent video mergers to combine MP4 videos. Most users recommend Filmora because it works flawlessly on MAC and Windows operating systems. Besides, it’s a user-friendly software that even non-professional people can use to join MP4 videos.

Q2. What is the fastest video merger for MP4 clips?

Filmora by Wondershare is one of the fastest video mergers. You can merge videos by working on the timeline, which ultimately saves your time. And you can export merged videos in MP4 or any other format without many struggles. The second and third options are Media Cope and Boilsoft Video Joiner. Although they are a bit old-fashioned, you will still find them more accessible and fast than other MP4 mergers.

Q3. How do I merge MP4 videos without losing quality?

Merging MP4 videos without losing the quality depends on your software to combine videos. Filmora never disappoints its users when it comes to quality. As a matter of fact, you can choose your own resolution from the export settings menu when saving the merged MP4 video in your Windows or MAC computer.
