Upload all your MP4 files, arrange them in the order you want, and click merge. The tool will combine them into one file.
Can I merge MP4 files with different resolutions?
+
Yes, but the output will match the resolution of the first video. Other videos will be scaled to match.
How many MP4 files can I merge at once?
+
Several files in one job need a paid plan. Free use is one file per conversion, one conversion an hour. On a paid plan you can add several files to one job, then download each result on its own or all of them in one ZIP.
Will merging affect MP4 quality?
+
We use high-quality encoding to minimize quality loss when merging your MP4 files.
Can I add transitions between merged MP4 clips?
+
Currently, the merge tool creates a direct cut between clips. For transitions, use our video editor.
Is merging free?
+
Yes, fundamental merging is free. Premium users get faster managing and larger file limits.
Does it work on mobile systems
+
Yes, our converter is fully responsive and works on smartphones and tablets. You can convert files on iOS, Android, and any other mobile platform with a modern browser.
Which browsers are handled
+
Our converter works with all modern browsers including Chrome, Firefox, Safari, Edge, and Opera. We recommend keeping your browser updated for the best interaction.
Are my files kept private and private
+
Uploaded files are processed on our own conversion servers, nobody looks at them, and they are not shared. The upload and the converted file are both deleted automatically about 24 hours after the conversion, which leaves time to download the result. See /privacy/ for the full policy.
What if my retrieve doesn't start
+
If your retrieve doesn't start by itself, try clicking the download button again. Make sure pop-ups are not blocked, and check your browser's download folder. You can also right-click the download link and highlight 'Save As'.
Will the resolution be preserved
+
It depends on the formats. A lossless target such as PNG, WAV or FLAC keeps what the source holds; a lossy target such as JPG, MP3 or MP4 is usually re-encoded, which trades some detail for a smaller file.
Do I need to create an subscription
+
No account is required for basic usage. You can process files immediately. Creating a free account gives you access to your conversion history and additional features.
