About this tool
Joining is the simplest edit: clip A, then clip B, then clip C. Add your videos, arrange the order, choose the output size, and press Merge. Portrait and landscape clips can be mixed; the blurred-background option fills the empty space so the result looks deliberate.
Everything runs locally, which is handy for personal footage you would rather not upload. Join clips from several phones, screen recordings and downloaded videos into one shareable file.
Why use ToolsCrow for this
- Any order. Arrows move clips up and down.
- Any mix of sizes. Blur, bars or fill.
- Any source. MP4, MOV, WebM and more your browser can read.
- Private. Files stay on your device.
Good to know
- Joining re-encodes the clips, so it is slower than copying. Every clip must be readable by your browser.
Frequently asked questions
Is my video uploaded to a server?
No. Everything runs inside your browser tab using your own device's video hardware. Your file is never sent to ToolsCrow or anyone else, which also means there is no waiting for an upload and it keeps working if your connection drops after the page has loaded.
Is it really free? Is there a watermark?
It is free with no sign-up, no watermark and no daily limits. The only limits are the ones your device sets: memory and processing power.
How large a video can I use?
Because the video is processed on your device, the limit is your device's memory rather than a server quota. Phone clips of several hundred MB are fine on most devices, and desktop computers usually handle 1 to 2 GB. Files over about 4 GB are not supported.
Which browsers work best?
Current Chrome, Edge and Safari (16.4 or newer, including iPhone and iPad) work best because they include the WebCodecs video engine. Recent Firefox versions work for many files. Older browsers fall back to a much slower real-time mode or may not work at all.
Can I join a portrait video with a landscape one?
Yes. Pick an output size and choose "Blurred background" so the shorter dimension is filled with a soft blur instead of black bars.
How many clips can I join?
There is no fixed limit; the practical limit is your device's memory and how long you are willing to wait for the re-encode.
