Drop videos to merge
Combine multiple video clips
Works with any file size -- files over 5000MB may just take a little longer
What is this tool?
Combines two or more video clips into a single video file, played back to back in the order you add them. Runs entirely in your browser -- your videos never leave your device.
How to use it
Upload your video clips in the order you want them to play, then download the combined video. Remove and re-add a clip to change the order.
Clips are re-encoded to a consistent format during merging, so mismatched resolutions or frame rates between clips won't break the merge -- but clips with very different qualities may still look uneven where they join. The size limit applies to all clips added together, not each one separately. Some phone-recorded videos (particularly .mov files) use a codec this tool can't read -- if processing fails right away, try re-exporting the video from your phone's own share options first.

Frequently asked questions
How to use Merge Videos
Upload your video clips in the order you want them to play -- each clip appears in a list, and removing and re-adding a clip changes its position if you need to reorder. Once your clips are arranged correctly, click merge and download the combined video. During merging, each clip is re-encoded to a consistent format, which is specifically what allows clips with different original resolutions or frame rates to merge into one coherent file without the merge simply failing on a mismatch.
When to use it
Useful for combining multiple short clips into one continuous video -- stitching together several phone-recorded clips from an event into one shareable video, combining an intro clip with the main content, or assembling a few short recordings into a single file for uploading somewhere that expects one video rather than several separate files.
When not to use it
If you need to actually edit within or between clips -- trimming specific sections, adding transitions, overlaying text or music -- this tool only concatenates clips end to end in the order you set; a fuller video editor is needed for those kinds of edits. For combining a very large number of clips or working with professional-grade footage where precise frame-accurate editing matters, dedicated video editing software offers control this straightforward merge tool doesn't.
Tips for best results
If a specific clip fails to process right when you upload it, try re-exporting or re-saving that clip from your phone or camera app's own share options before re-uploading -- this often resolves codec-compatibility issues without needing to find alternative software. For the most visually consistent result, use clips recorded at similar resolution and quality settings where possible, since re-encoding smooths over format differences but can't fully mask an underlying quality gap between a high-resolution clip and a low-resolution one merged together.
Limitations
Because all clips are re-encoded during merging, clips with very different original quality levels can still look visually uneven where they join, even though the technical merge itself succeeds -- re-encoding solves the format-compatibility problem, not an underlying quality mismatch between source clips. Some phone-recorded videos, particularly certain .mov files, use a codec this tool can't read; if a specific clip fails to process, re-exporting it from your phone's own share/export options first usually resolves it. There's also an overall size limit that applies to all clips combined, not to each clip individually.
Privacy
Merging happens entirely in your browser -- your video clips are never uploaded to a server at any point in the process, which is also why merging longer or higher-resolution clips takes real, noticeable processing time on your own device rather than happening instantly on a server.
