MultiKit

Supported browsers

MultiKit runs in your browser, so what a tool needs is a set of browser features. Here is the first version of each of the six main browsers that has them.

  • Chrome119+
  • Edge119+

These tools need no feature of note: they are built for current browsers and are tested in Chrome.

What these numbers mean

The numbers come from MDN's compatibility data and give the first version that has the main features a tool relies on. The true minimum can be a little higher. They say nothing about codecs: whether your browser can read or write a certain audio or video format also depends on your device, so each audio and video tool shows a list of what your browser can make. We test in Chrome; the other browsers follow the data, not our own testing.
