How to use it

  1. 1Drop your clips onto the box, or click to choose two or more videos from your device.
  2. 2Reorder them with the up and down buttons so they play in the sequence you want, and remove any you do not need.
  3. 3Click Merge videos — the in-browser engine stitches them into one file.
  4. 4Play back the merged result and download the combined MP4.

Merging videos is one of those small jobs that comes up constantly. Maybe you recorded a walkthrough in several takes and want them back-to-back as one continuous clip. Maybe you are assembling an intro, a demo, and an outro into a single file to upload. Or maybe you just have a folder of short clips that belong together. In every case you want one tidy video out the other end, in the order you chose, without wrestling a full editor.

This tool does exactly that. Everything runs entirely inside your browser using an in-browser video engine — there is no upload, no server, no watermark, and no account. The clips you add stay on your machine the whole time, which makes it safe for confidential demos, client work, and anything you would rather not hand to a website. Nothing is ever sent anywhere.

You can add as many clips as you like, drag in more at any time, reorder them with the up and down buttons, and drop the ones you do not want. When you click Merge, the clips are joined in the exact order shown and re-encoded into a single standard MP4 that plays everywhere and imports cleanly into editors. Because merging re-encodes every frame, it is heavier than tools that only copy a stream, so a handful of short clips is the sweet spot.

One tip for reliable results: clips that share the same format, resolution, and frame rate — and that all contain an audio track — merge most dependably. Mixing wildly different sources, or combining a clip that has sound with one that is silent, can occasionally trip the merge up. When that happens, the tool tells you, and re-exporting your clips to a consistent format first usually fixes it.

FAQ

Is this tool free?
Yes — completely free, with no sign-up, no watermark, and no limits. It runs entirely in your browser.
Are my videos uploaded anywhere?
No. Everything happens locally in your browser. The clips are never sent to a server — they stay on your device the entire time.
How many clips can I merge?
You need at least two clips, and you can add as many as you like. Because merging re-encodes every frame in your browser, a handful of short clips works best — very large or numerous clips can be slow or run out of memory.
Do the clips need to be the same format and resolution?
You get the most reliable results when clips share the same format, resolution, and frame rate, and all contain an audio track. Very different sources, or mixing a clip with sound and a silent one, can occasionally cause the merge to fail.
Why does the first run take a moment?
The first time you use it, your browser downloads the in-browser video engine (about 30 MB) once. After that it is cached, so later runs start instantly.
