How to Convert WebP Images to JPG or PNG and Vice Versa on Mac

Google developed the WebP image format as an alternative to JPEG and PNG for websites. Google’s PageSpeed Insights defines it as a “next generation format”and recommends that websites use WebP (and AVIF) images as they load faster due to their smaller file size compared to other popular formats.

As a result, many popular sites use WebP. So, when you upload an image, you may find that it has an extension. webp at the end of the filename.

If you’re having trouble working with WebP images in certain applications, we’ll show you the easiest ways to convert them to JPG, PNG, HEIC, or other formats on your Mac.

Convert WebP to JPG, PNG, HEIC, etc.

1. Use a preview app

Double click the downloaded WebP image and it should open in Mac Preview. If it isn’t, right-click the image and choose Open With > Preview.
Click “File”on the top menu bar and select “Export”.
Click the Format drop-down menu and select HEIC, JPEG, JPEG-2000, OpenEXR, PDF, PNG, or TIFF.
Set the Quality slider to between Least and Best.
Finally, make sure the export folder is correct and click the “Save”button.

Preview converts the WebP image to JPG, PNG, or your chosen format and saves it. Now you can use it almost everywhere as almost all apps, websites and services support JPG or PNG formats.

2. Use Quick Actions

Follow these steps to convert a WebP image to JPEG or PNG on a Mac running the latest version of macOS, such as macOS Monterey or macOS Ventura:

Right-click or Control-click over the WebP image.
Choose Quick Actions > Convert Image.
Choose a format: JPEG, PNG, or HEIF.
Select an image size: Small, Medium, Large, or Actual.
You can then choose to keep or remove the image’s metadata by checking the “Keep Metadata”checkbox.
Finally, click “Convert to JPEG”(or PNG/HEIF).

Finder converts the WebP image to JPG, PNG, or HEIF of your choice and saves it in the same folder as the WebP image.

3. Use the Photos app.

If you’ve added WebP images to the Photos app on Mac, here’s how to convert them to another format:

In the Photo Type section, choose JPEG, PNG, or TIFF.
