How to convert Video to MP4

  1. 1

    Choose your Video files

    Click the upload area or drag files onto it. Nothing is uploaded — files are opened locally.

  2. 2

    Adjust the settings

    Pick output format and quality, then press the convert button.

  3. 3

    Download the result

    Save each file individually or everything at once as a ZIP.

One converter for every video format. Pick the output — MP4 for phones and the web, WebM for websites, MOV for Apple editors, MKV, an animated GIF, or just the MP3 soundtrack. Conversion runs on your device; files are never uploaded.

What is Video?

MP4, MOV and WebM videos are supported as input.

What is MP4?

MP4 is the most widely supported video format, used by phones, cameras, YouTube and every social platform.

Is it private?

Yes. Unlike upload-based converters, ZapMorph processes files inside your browser tab, so the file stays on your device. It is never transmitted, stored or logged — close the tab and it’s gone.

Frequently asked questions

Is the video converter free?

Yes, once a day. Convert one file up to 25 MB a day without an account. A free account gets one run a day on any Pro tool with files up to 50 MB; Pro and Lifetime plans are unlimited.

Are my files uploaded to a server?

No. The conversion runs entirely in your browser, so your files never leave your device. We only count how many files you convert — never their names or contents.

What is the maximum file size?

Up to 25 MB per file without an account, 50 MB with a free account, and 1 GB on Pro. Very large files also depend on your device’s memory.

Can I convert multiple Video files at once?

Yes. Select several Video files at once — up to 5 on the free plan or 50 on Pro — and download all results in a single ZIP.

Does it work on Mac, Windows, iPhone and Android?

Yes. It works in any modern browser — Chrome, Edge, Firefox and Safari — on desktop and mobile, with nothing to install.
