To save a webpage image in desktop Chrome, right-click it, choose Save image as, and select a location if prompted. Then check the saved file: downloading does not guarantee it is a JPEG. If it is another format, convert it with an image app—for example, Preview on a Mac can export an image as JPEG.

Download the image in desktop Chrome

  1. Open the webpage with the image in Chrome.
  2. Right-click the image and choose Save image as.
  3. If Chrome asks where to save it, choose a folder and click Save. If no prompt appears, look in Chrome’s configured Downloads location or the download tray. Chrome can be set to ask where to save each file in its download settings. See Google Chrome Help for its current desktop instructions.

This saves the image resource Chrome provides; it does not necessarily change that resource into JPEG format.

Check whether the downloaded file is already JPEG

Look at the filename extension: .jpg and .jpeg are both commonly used for JPEG files. If the file has one of these extensions, it may already be in the format you need. When the format matters—for example, because a site or app requires JPEG—confirm it in an image application rather than relying only on the filename. Changing an extension does not convert the image’s encoding.

A webpage may provide an image in a different format, such as WebP or PNG. In that case, use an application’s export or conversion function to make a JPEG copy. Keep the original if you may need its format or image quality later.

Convert an image to JPEG with Preview on Mac

  1. Open the downloaded image in Preview.
  2. Choose File > Export.
  3. Open the Format menu and choose JPEG. Adjust quality if the control is available and you need to.
  4. Choose a filename and destination, then click Save.

Apple documents this workflow in its guide to converting image file types using Preview on Mac. Exporting creates a JPEG; simply renaming a WebP or PNG file with a .jpg ending does not.

Choose JPEG only when it fits the image

JPEG is a lossy format for still images and is widely supported. Its compression can reduce file size, but it does not support transparency. PNG is usually the better fit when you need a transparent background or more precise reproduction. WebP and AVIF have different compression and capability trade-offs, and support can vary by app or site.

MDN’s image file type and format guide describes JPEG, PNG, WebP, and AVIF properties and common extensions.

If the image does not save as expected

Browser menus and file handling differ. Firefox, for example, can open supported file types in the browser, save them, or open them in a system or default application, depending on the content type and configured action. If you do not see the Chrome steps above, check the help for your browser and device rather than assuming the same menu labels apply. Mozilla explains Firefox’s file types and download actions.
