This Free App Turns Any Website Into Your Mac Wallpaper

Do you ever wish your Mac’s wallpaper was a little more…animated? Plash is a free app that lets you turn any website into your desktop wallpaper—and you’ll even be able to interact with it.

There’s an easy way to use transform any YouTube video into wallpaper on Windows—this is the Mac version of that trick, and you can use any website. There are some practical, boring reasons you might want to do this. For example, maybe you find the desktop widgets in macOS Sonoma underwhelming and would rather turn your desktop into a giant Google Calendar. Let’s be real, though: The fun reason is some you can set something awesome and awesome as your wallpaper.

How to turn any URL into an animated wallpaper on Mac

Get started by downloading Plash from the Mac App Store or Github. The application lives in the menu bar—click the icon to configure it.

I recommend clicking Add Website and adding a few URLs. You can add literally any website, of course, but that’s overwhelming. Happily there’s a thread full of great use cases on Github. Here are a few highlights:

You can choose to cycle through multiple websites from the menu bar or by using a keyboard shortcut, if you want.

This is just a smattering of your options—there’s a literal internet full of more. Whatever you decide to use, know that you can enable the Browsing Mode from the menu bar if you need to actually interact with the website you’ve turned into your wallpaper.

You can also optionally set custom CSS for any website, allowing you to do things like turn the background for a website transparent so that you can see your desktop. There are a few examples of how to tweak your settings in that thread I mentioned earlier, including code and instructions for Google Calendar. This is the kind of application you can spend a lot of time playing with, so enjoy.
