If you’ve ever double-clicked a file on your Chromebook and thought, “Why is it opening in this app?” — you’re not alone. ChromeOS usually selects a default app automatically based on the file type, but it doesn’t always get it right. Sometimes it chooses a basic viewer when you’d rather use a more powerful editor, or it keeps opening files in an app you barely use.
The good news is that you can easily change the default app and take full control over how your files open. Whether you want PDFs to open in a different viewer, images to launch in a specific editor, or media files to play in your favorite app, ChromeOS gives you the flexibility to customize it.
In this guide, we’ll walk you through exactly how to change default apps on a Chromebook, explain how the “Open with” option works, and share a few useful tips to make the process smoother and more efficient.
Why You Might Want to Change Default Apps
Before we jump into the steps, let’s quickly understand why this matters. By default, ChromeOS may open images in the Gallery app instead of a Linux editor, launch PDFs in the browser instead of a dedicated viewer, or use basic apps when you’d prefer more advanced ones.
Changing the default app helps you save time by avoiding repetitive “Open with” selections. It also improves productivity by letting you use your preferred tools and gives you more control to customize your overall Chromebook experience.
How to Select an App to Open Files on Chromebook
If the file you try to open launches in an app you don’t prefer, you can manually select the right app of your choice to open it. For example, if you try to open a PDF and it opens in the Chrome browser, but you have installed Adobe Acrobat Reader and want to use that instead, you can manually select it. Here’s how:
1. Open the Files app on your Chromebook.
2. Navigate to the file you want to open, then right-click on it and select the Open with option.
3. A context menu will appear showing all the supported apps that can open that file type. Select your preferred app, and the file will open in that application.
However, this will not set the selected app as the default. It will only apply for that instance. If you want to always open the same file type in your preferred app, you’ll need to change the default app for that file type.
How to Change Default App on Chromebook
Now, if you don’t want to repeat the Open with method every time, you can permanently set a default app for each file type using the Change default option in the Files app context menu.
This allows you to always open files in your preferred app. However, make sure that the app is installed on your Chromebook, whether it’s an Android app from the Play Store, a Linux app, or a web app (PWA).
Here’s how you can change default app on a Chromebook:
1. Open the Files app on your Chromebook.
2. Navigate to the file location.
3. Select the file, then right-click on it and choose the Open with option.
4. Click on the Change default option in the context menu.
5. You’ll see a list of apps that can open the selected file type. Select the app you want to set as default.
Similarly, you can do this for other file types. From now on, every time you open that file type, it will automatically launch in your selected default app.
Wrapping Up
Changing the default app on a Chromebook might seem like a small tweak, but it can make a big difference in how smoothly your workflow runs. Instead of dealing with the frustration of files opening in the wrong app every time, you can take control and ensure everything opens exactly the way you prefer.
Once you set your default apps, you’ll spend less time fixing these small annoyances and more time getting things done efficiently.
