🎬 Video Merge
Join several clips into one file. Nothing is uploaded.
Works on clips that already match. The clips are copied into one file rather than re-encoded, so merging takes seconds and loses no quality — but it only works when every clip has the same codec, resolution, frame rate and audio settings. Recordings from one camera, or exports made with the same settings, always qualify. If yours differ, the tool will say which setting does not match; convert them to matching settings first.
Frequently Asked Questions
Are my videos uploaded to a server?
No. The clips are joined locally in your browser. They never leave your device.
Why does it say my clips cannot be joined?
This tool joins clips by copying them into one container, without re-encoding — which keeps the original quality and takes seconds instead of minutes. Copying only works when every clip has the same codec, resolution, frame rate and audio settings. When they differ, the message names the property that does not match.
Which clips will always work?
Clips recorded back-to-back on the same camera or phone, and files exported from the same editor with the same settings. Those already share every parameter.
My clips differ. What can I do?
Run them through Video Convert first with the same output settings for each, then merge the results.
Does merging reduce quality?
No. Nothing is re-encoded — the original video and audio data are copied through untouched.
Can I reorder the clips before merging?
Yes. Drag the thumbnails to set the order, then merge.
Is the tool free?
Yes, completely free. No account, no sign-up, no watermark.
