[Free MP4 Joiner] How to Join MP4 Files Free and Readily?

Simple Guide: How to Merger MP4 Files Free in 4 Steps?

Step 1 - Add Multiple MP4 Files

Run Free HD Video Converter Factory and open "Converter" module. Press "Add Files" button to add all the MP4 video files you want to merge. Alternatively, just drag and drop the MP4 videos to the interface.

Note: In addition to MP4 files, it supports nearly all common video formats like MKV, AVI, MOV, M4V, MPG, etc., but make sure you add at least two and more MP4 files into the program for joining, otherwise, the "Merge" button on the top bar will be gray and non-clickable.

Step 2 - Combine MP4 Files into Packs

Open the "Merge" window on the top bar, where you can free merge MP4 files in an arbitrary order. Press the middle "Merge" button to create a "Pack 1" in the below section. Move those MP4 files from "Video List" section to the "Pack 1" timeline. Then drag and drop those MP4 files to re-arrange the order. Once everything is all set, hit the bottom "Merge" button to go back.

Tips: You can create multiple packs like Pack 2, Pack 3, etc. to re-arrange and join different MP4 files, which is an efficient feature that most other free MP4 mergers don't have.

Step 3 - Select an Output Video Format

Click on the format profile on the right side to expand the full list of 500+ presets. If you prefer the original MP4 format, just navigate to "Video" category and select "MP4" profile as the output video format. Similarly, you're able to select any video, audio, or specific device profile as you wish.

Step 4 - Start Joining MP4 Files Together

You're almost done! Specify a destination folder to save the combined MP4 footage on the bottom, lastly, hit "Run" button to start the MP4 files joining process.

Optional - Modify Parameters & Other Editing Features

Before conversion, you're even allowed to modify video parameters by clicking on "Parameter settings" button underneath the format profile, such as alter video resolution, change video codec, bit rate, aspect ratio, frame rate, increase video volume, deinterlace video, etc. But to join MP4 files without re-encoding, you're recommended to keep the original settings.

More surprisingly, this MP4 merger freeware comes with a basic editing toolbar, enabling you to trim, split, crop, rotate, flip, filter, watermark video files with ease. The "Downloader" module can even help download video and music from YouTube and more than 500 popular websites.

MP4Tools is a completely free and open source program designed to manipulate MP4 files. It incorporates both MP4Joiner and MP4Splitter, allowing you to join multiple MP4 files into one and split an MP4 file in multiple parts, without re-encoding and quality loss. As it's a GUI/frontend for CLI-based FFmpeg and MP4Box, you don't worry about the command scripts. Here's how to merge MP4 files free with MP4Joiner.
