    Frequently asked questions

    What if the videos are different sizes?

    They are fitted to the size of the first one without being stretched: black bars are added when needed (for example a vertical video between horizontal ones).

    Is a video without sound a problem?

    No: silence of the same length is added so the sound stays in sync with the picture.

    How many videos can I merge?

    As many as you like: the only limit is your device’s memory.

    Are my files uploaded to a server?

    No. Processing happens entirely in your browser, on your device. No file is uploaded or stored. You can check: once the page has loaded, disconnect from the internet and the tool still works.

    Is there a file size or number limit?

    No. Since nothing goes through our servers, there is no quota. The only limit is your device's memory: a computer handles very large files more easily than a phone.

    Is it really free?

    Yes. No sign-up, no watermark added to your documents and no usage limit.
