Question details

The user wants to change the default 'Save As' image format in Windows 11 from PNG to JPEG/JPG, as modifying the default image viewer settings does not affect the save format.

How to Change the Default Save As Format to JPEG in Windows 11

Product: Windows 11 Built-in Apps
Device & OS: Windows 11
Scenario: Saving screenshots or edited images using default Windows applications like Snipping Tool, Print Screen, or Photos.
Observed behavior: The 'Save As' dialog persistently defaults to PNG format. Changing the default Windows application for opening JPG files does not change the format selected during the 'Save As' process.

Before you start

Identify the specific application you are using to save the image (e.g., Snipping Tool, Paint, or Photos), as the 'Save As' default is controlled by the individual application's settings, not by Windows 11 system file associations.

Solution 1Recommended

Manually Select JPEG in the Application's Save As Dialog

Since Windows 11 does not have a global 'Save As' format setting, you must manually change the format in the application you are using.

The available export formats are determined by the internal coding of the application you are using to save the image. Modifying your default app for opening files only affects viewing, not saving.

Open the Save As menu

After editing or capturing your image in an app like Snipping Tool or Photos, click the 'Save' or 'Save As' icon, or press Ctrl + S on your keyboard.

Locate the format dropdown

In the Save dialog box that appears, look for the 'Save as type' dropdown menu located just below the 'File name' text field.

Change PNG to JPEG

Click the dropdown menu, scroll through the list of supported formats, and select 'JPEG file (*.jpg, *.jpeg, *.jpe, *.jfif)'.

Save the image

Click the 'Save' button. The application will now export your image as a JPEG.

Manually Select JPEG in the Application's Save As Dialog

App Memory: Some third-party image editors will remember your last used format (JPEG) for future sessions, but built-in apps like Snipping Tool often revert to PNG.

Solution 2

Use Microsoft Paint for Quick JPEG Conversion

If an app only allows you to save as PNG, you can use Microsoft Paint as a quick intermediary tool to save the image as a JPEG.

Frequently Asked Questions

Why didn't changing the default image viewer to JPG fix the Save As format?

Changing the default Windows 11 application for JPG files only tells the operating system which program to use when you double-click to open an existing file. It does not dictate how other applications generate or encode new files during the 'Save As' process.

Can I permanently force the Windows 11 Snipping Tool to save as JPEG?

Currently, Windows 11 does not offer a built-in settings toggle to permanently change the Snipping Tool's default save format from PNG to JPEG. You must manually select JPEG from the 'Save as type' dropdown each time you save a new screenshot.

Why does Windows 11 default to PNG for screenshots?

Windows 11 defaults to PNG for tools like Snipping Tool and Print Screen because PNG is a lossless format. This ensures screenshots remain crisp, preserving text readability and sharp lines without introducing the compression artifacts common in JPEG files.
