The Top 5 Free Apps to Merge or Split Video Files
Whatsapp Pinterest

Editing videos can be surprisingly complex. Using a serious tool like Adobe Premiere Pro, it could take days to comfortably cut your first video into smaller clips, or merge videos together into a single larger clip.

What are you to do when you don’t have that kind of time? What if you just want to merge videos together one time and don’t want to install a full-blown video editor like Final Cut X or HitFilm Express?

Don’t worry, you have options! There are many free tools for splitting and merging video files—the tricky part is finding the ones worth using. Learn how to merge videos together (or split videos apart) using these best apps for merging and splitting videos.

1. MP4Tools

MP4Tools is an open-source project that consists of two utilities, making it a free video merger and free video splitter in one.

MP4Splitter is for splitting an MP4 video file into multiple pieces:

MP4 Splitter

MP4Joiner is for merging MP4 video files together:

MP4 Joiner

No other video types are supported, but seeing as how MP4 is the most popular video format, that’s not a huge problem.

Actually, it’s a benefit! MP4Tools can split and merge MP4 videos without re-encoding. Re-encoding takes time and often results in a loss of quality, which is why MP4Tools can do instant cutting and joining at source quality. This is why it’s our favorite free video merger app. However, you can force re-encoding if you’d like.

Splitting is as easy as loading a video file, adding “split points,” then clicking Start splitting. Merging is even easier: add the individual video files, then click Join.

2. Machete Video Editor

As far as lightweight video merger and editor apps are concerned, Machete Video Editor is one of the best. As long as you output videos with the same settings as your source videos, it will not re-encode.

The downside to the Lite version of Machete is that it only works with AVI and WMV formats. To unlock FLV, MP4, MKV, MOV, and several additional audio formats, you’ll need to purchase the full version. This is the only limitation of the Lite version.

Machete video editor

To split a video, click Play > Jump to time… and navigate to a starting timestamp, then click the Set the beginning of a selection button. Navigate to an ending timestamp and click Set the end of a selection. Then click Save the selection as… to export the clip.

To merge videos, load the first clip (it can be any, doesn’t have to be the first in order). Use Play > Jump to time… to navigate to where you want to insert the next clip, then click Edit > Insert a file at the current position… Repeat for all clips, then File > Save As… to finish.

3. Format Factory

I hesitate to recommend Format Factory because it requires over 150 MB to install—a hefty amount of space if all you want to do is split and merge video clips. But if you also need to convert between formats and/or rip from CDs and DVDs, then it may be worth your while.

Format Factory

To split a video, click the output format you want in the sidebar, then click Add File and load the video. Click Option, set the Start Time and End Time to wherever you want the split, then click OK. Lastly, click Start to begin the splitting task.

Video Joiner in Format Factory

To merge videos, go to Utilities > Video Joiner in the sidebar. Set the proper Output Setting, then click Add File to load all of the individual clips. Lastly, once everything is ordered properly, click OK and then Start to begin the merging task.

Download: Format Factory (Free)

Note: You may see an “Unsafe Website!” warning for Format Factory claiming that it distributes spyware/malware. As long as you uncheck the bundleware during installation, it’s fine. That said, use at your own risk The Safest Free Software Download Sites for Windows The Safest Free Software Download Sites for Windows Many software download sites are loaded with malware.

4. Avidemux

While Avidemux is technically a video editor, it has nowhere near the same complexity as a professional video workstation. It’s simple enough that you only have to click a few buttons to do what you want, especially if you only need to split and merge videos.

Avidemux supports AVI, FLV, MP4, MPG, and MKV formats, which covers about 99 percent of all modern videos. Furthermore, Avidemux won’t re-encode if your output settings are the exact same as the input, thus saving time and preserving video quality.

Avidemux

To split a video, load it and click Time at the bottom, set the starting timestamp of the split, then click the Set start marker button. Next, navigate to the ending timestamp of the split, then click Set end marker. Lastly, click File > Save to save everything between markers as a clip.

To join videos, load the first clip with File > Open, then load subsequent clips with File > Append. You must do it in the order you want them merged! Save the combined video with File > Save.

Download: Avidemux (Free)

5. Freemake Video Converter

Freemake Video Converter supports over 500 video and audio formats and is easy to use, but the free version adds a watermark. For $9 per year (or $19 lifetime payment), the watermarking is removed and video conversions are even faster. Unfortunately, splitting and merging always re-encodes.

Freemake video converter

To split a video, load it with the +Video button, then click to edit. Use the playback timeline and the Start Selection and Selection End buttons (under the Cutting section) to select a timeframe. When finished, click OK and then one of the output buttons at the bottom to export.

Splitting video in Freemake video converter

To merge videos, add as many clips as you want with +Video, and then enable the Join files toggle at the top right. Drag and drop to sequence the clips, then click one of the output buttons at the bottom to export.

Split and Combine Video Clips With Ease

Going forward, you should also learn how to reduce video file sizes without sacrificing quality, which comes in handy when doing all kinds of video editing. Also, don’t miss out on the nuances of video codecs, containers, and compression!

    I once tried Avidemux, but it always crashed. Then i switched to Joyoshare Media Cutter, really easy to use, help me split and merge video clips in a simple way. But its free version only allows me to cut for 5 times, and then I need to pay for it.

    MP4Tool split my video of two hours and a half in less than twelve minutes. No more movies left in half because my USB and TV do not let me see videos more than two hours long!!! It should be call MP4Magic.

    I've also used MKVToolNix GUI. I loaded the first MP4, appended the rest to it, and then multiplexed them into an MKV. But I would discard the joined file and resort to re-encoding if warnings or errors are given.

    Tried several times to join MP4 videos using MP4 software. A complete waste of time as the end result was hours and hours of video when it should have been 95 minutes.
    I looked at the 'support' and 'forum' to see the same problem identified but no answers. The support page should be re-named 'lack of support' as clearly no-one is responding. Huge disappointment and now uninstalled.

    Format Factory is good but it allows only 50 videos maximum.

    Please remove this page! I tried downloading three of these apps so far, and they all gave me malware, and a slew of unwanted add-on programs. The apps did not even work for joining my videos!

      I will in fact, not be using any of the video editors suggested on this page - mainly the ones that are outed of malware etc because of what you experienced. Thank you for your useful comments.

Users can choose whether to add the fade in/out effect to videos by their own wills. It supports joining the same format video files without encoding SUPER-FAST merge and supports joining different formats of video files and select any format one of the file as the output format, or set a custom output format.

    So apparently, there is no simple little program to cut the end off of a .wmv file that Premier Elements somehow produced as 27 minutes, only 13 of which is the movie. The ending balance is all black and I've found no easy way to trim it. PE wants you to cut it, then render and export in the same format, which takes a lot of work and time. One would think it would be a simple project.

    well, Convert .MTS(AVCHD), or Split Or Merge, you can get ifunia AVCHD Converter.
    it's a professional AVCHD converter, but have to add one is it's not free(more details: http://www.ifunia.com/avchd-co... ).
    Of course, free is popular by masses. However, some of the premium packages and services appear to be well worth their nominal fees when you consider everything they provide.
    The Format Factory is really great listed, I alway use it, but it can work on some formats too, such as MOD, so then I turn to some professional multimedia software developer.

    I've used most of the tools cited but I am surprised that one of the best, (imho) isn't mentioned.

    Always reliable and easy to use: AVS Video Converter!

      I don't think it's free as you have to buy a license either for one or for their bundle of products.

      I think the tool for .MTS files should be TsMuxeR . You can try it out.
