How to Merge Videos on Windows (Incl. Lossless Solution)

WonderFox HD Video Converter Factory Pro is our top recommendation for Windows users who wish to merge videos without loss of quality. Although it's primarily a video converter, it's equipped with a powerful merging tool that can help you easily merge two or more video clips into one file. And because it's a video converter, it supports almost any video, including MP4, MKV, MOV, AVI, WMV, MPEG, M4V, WebM, FLV, and some less common formats.

As mentioned, the software is ideal for merging videos without losing quality. This is because it can directly splice videos together with identical parameters without re-encoding. In other words, if your videos share the same encoder, resolution, frame rate, and aspect ratio, such as videos shot by the same camera (like a GoPro), you can use this software to combine them with zero quality loss. Additionally, you can still merge videos of different resolutions, sizes, and formats while maintaining high quality.

The software is easy to use. You can download download the software for free and follow the tutorial below to merge your clips:

If you prefer not to install third-party software, Windows features native built-in editors: the legacy Photos Video Editor on Windows 10 and Clipchamp on Windows 11. While convenient, remember these are designed for basic edits, and the export quality is capped at 1080p HD.

- Photos Video Editor (Windows 10)

The Video Editor app can easily merge various types of videos, including MP4, AVI, WMV, and MOV, into a longer MP4 file. However, it does not support some videos like HEVC/H265 and VOB. Here is how to put two videos together in Video Editor.

Step 1: Open the Photos app on your Windows 10 and select Video Editor. Or you can type "video editor" in your Windows search box to open the video editor app directly.

Step 2: Click New video project and name your video.

Step 3: Click Add to add your video files to the project library.

Step 4: Drag the two videos into the Storyboard below and rearrange the order if needed. The videos are automatically joined and you can preview the video in the video player window.

Step 5: Click Finish video > Export to save the merged video to your local folder.

- Clipchamp (Windows 11)

On Windows 11, Clipchamp replaced Video Editor to be the default video editor app. It supports a wider range of supports than Video Editor, and you can combine HEVC videos in it. But for smooth video export, the total length of the final video should be less than 10 minutes. So Clipchamp is only recommended for merging a few short video clips.

Step 1: Search Clipchamp in the Windows Start menu and open the app.

Step 2: Sign in to Clipchamp.

Step 3: Select Create a new video.

Step 4: Click Import media to import your video files.

Step 5: Drag and drop the files onto the timeline and change the order as needed. The videos are placed next to each other and can be played as one video in the video preview player.

Step 6: Click the Export button and your videos will be exported as one MP4 video.

There are more options to merge videos on Windows, including open source tools like Avidemux and online services like Clideo.com.

- Avidemux (Open-source)

Avidemux is a lightweight, open-source video trimmer program but can also be used to merge videos losslessly. Like WonderFox, it can also simply stitch videos together without re-encoding, so no loss of quality. But it does not have a very friendly user interface, and the steps are a bit more complex. For instance, once you have imported the first video into the program, you need to click ‘File' > ‘Append' to import the second, the third, and more videos you want to combine. Note that you cannot rearrange the order of videos once they are loaded inside the software. The videos will be combined strictly in the order you add them.

Step 1: Download Avidemux and launch it.

Step 2: On the top menu of the interface, click "File" > "Open" to import a video file.

Step 3: Click "File" again and then navigate to the "Append" section. Select the video you want to join together and click "Open". Then the two videos are combined on the timeline. You can press the playback icon to preview them. To join more videos, you need to repeat the process.

Step 4: You can select the desired video output, audio output, and output format in sequence on the left side of the interface. Generally, for best compatibility, Mpeg-4 AVC (x264) video, AAC or MP3 audio, and MP4 (MKV) Muxer combination is recommended. Then press the save icon or click "File" > "Save" to download the merged videos to your desired folder.

- Clideo (Online)

Online solutions are recommended if you don't want to or can't use the desktop software.

Clideo is one of the leading video editors online. It allows you to quickly merge video files online for free. You can upload two or more videos, as long as they don't exceed the 500 MB size limit, and combine them with one click. It's very easy to use this tool and no sign-up is required. Note, however, that the exported video will have a clideo.com watermark that needs payment to be removed.

Step 1: Go to the Clideo Merge Video website at https://clideo.com/merge-video.

Step 2: Click "Choose Files" to upload your videos onto the platform.

Step 3: Adjust the video as you like.

Step 4: Click "Export" and download the final video to your computer.

Merging videos on Windows is a simple task with the right tools. For quick and casual edits without the need to install additional software, the native tools of Windows: Photos Video Editor or Clipchamp are sufficient. If you want ultimate convenience and don't mind file size caps or watermarks, Clideo is also a good option. But if you need a fast workflow without quality loss, especially for merging clips like GoPro videos, the desktop software is the answer, and for a smoother user experience, WonderFox HD Video Converter Factory Pro is your best bet.

1. Which is the best program to combine GoPro videos?

Of all the tools introduced here, WonderFox HD Video Converter Factory Pro and Avidemux are two programs best suitable for combining GoPro videos.

2. Can I merge videos without losing quality?

Yes. Tools like WonderFox HD Video Converter Factory Pro allows you to merge videos without losing quality (no re-encoding) as long as the source files are with identical parameters, namely, same encoder, resolution, frame rate, and aspect ratio.

3. Can I combine videos of different resolutions?

Yes. In fact, you can combine videos of any resolution, any size, and any format. But it's best to unify the aspect ratio first so there won't appear black bars. Or if you want faster merging, unifying your videos using the same encoding settings is also recommended.

4. How many videos can I merge at once?

There's no set limit, but remember that the more files you add, the longer it'll take.
