About this tool

All videos are converted to match the dimensions and frame rate of the first video in the list. Videos with a different aspect ratio (for example, a vertical video after a horizontal one) get black bars without stretching the image. Segments without audio get silence, keeping the audio in sync.

A note about limits: the final video is assembled in your device's memory, so the total file size is limited to 2 GB. Re-encoding speed depends on your processor and graphics card. On computers, it usually takes less time than the videos' total runtime; on phones, it may take longer.

Frequently asked questions

Can I merge videos with different dimensions?

Yes. The output matches the dimensions of the first video, and videos with a different aspect ratio are fitted with black bars. Add the video with the dimensions you want first.

Why does this take longer than trimming a video?

Merging videos from different sources requires re-encoding every frame. Trimming only copies the data. Choose 720p to speed things up.

Which browsers does it work in?

Chrome and Edge on desktop offer the best support (they create MP4 H.264 files). Recent versions of Firefox and Safari also work. If your browser can't encode H.264, the output will be WebM.

Are my files uploaded to a server?

No. This tool runs entirely in your browser: your file is read and processed on your device, and not a single byte is sent over the internet. You can even disconnect from the internet after the page loads.

Is it really free? Is there a daily limit?

It's free with no daily limits. Processing happens on your device, so there's no per-use cost and no need to limit you.

Does it work on phones?

Yes. The site works in any modern browser on Android, iPhone, Windows, Mac, and Linux—no installation needed.
