Use your browser’s save command to download the image, then check its actual format. If it is not JPEG, export a copy from an image app with JPEG selected. Renaming a file to end in .jpg does not convert it.
Download the image from the webpage
Chrome on a computer
- Right-click the image and choose Save image as.
- Choose where to save it and confirm. Chrome’s command downloads the image; it does not promise to convert it to JPEG. The saved format depends on what the site provides. See Google Chrome Help.
Safari on Mac
- Control-click the image.
- Choose Save Image to Downloads or Save Image As, then follow the prompts.
Some images, including certain webpage background images, cannot be saved through this menu. Apple describes the Safari options and limitation in its Safari webpage-saving guide.
Check whether the downloaded file is JPEG
Look at the file’s actual format in an image app or your computer’s file manager. Web images can be provided in formats such as WebP, PNG, or HEIF as well as JPEG; the file extension alone is not conclusive. Apple’s overview explains some formats used on the web, but a site’s format for a particular image depends on what it serves: Apple Developer’s WWDC23 media-formats session.
If the image is already JPEG, you can use that downloaded file. If it is another format, export a separate copy and explicitly choose JPEG. Do not change only the filename extension: that leaves the image encoded in its original format.

Choose JPEG only when it fits the image
- Use JPEG when a website or app specifically requests it, or when you need a widely supported image format. Exporting can reduce image quality, depending on the quality setting.
- Keep the original for transparency. JPEG does not preserve a transparent background. For a transparent graphic, keep the original or export to a format with alpha support, such as PNG.
Apple’s Preview export instructions distinguish JPEG’s size and quality options from alpha controls available for formats including PNG, HEIC, and TIFF. See the Mac guide and the iPhone guide.
Apple also explains how to export HEIF images to JPEG using Photos or Preview on Mac. Its “Most Compatible” camera setting concerns future photos taken on an Apple device; it does not change the format of an image downloaded from a webpage. See Apple’s HEIF and HEVC guide.

Troubleshooting
- There is no save-image option: The image may be a page background or otherwise unavailable through the browser’s image menu. Safari’s menu does not support every image. Try the site’s own download option if it provides one.
- The downloaded file is WebP, PNG, or another format: That is the format the site supplied. Open it in an image app with export controls and select JPEG rather than renaming the file.
- The JPEG has a solid background instead of transparency: This is expected; JPEG does not retain transparency. Keep the original or use a format such as PNG that supports alpha.
- The converted image looks worse: JPEG export can reduce quality. Re-export from the original with a higher quality setting, or retain a lossless/transparent original when those properties matter.
Or skip the browser setup
If you need a screenshot of a webpage rather than the original image file, ScreenshotNeo can return a screenshot as PNG, JPEG, or WebP, or a PDF. Its API takes one GET request; the screenshot is of the rendered page, not a download of the source image.
For example, this requests a JPEG screenshot of a page. See the ScreenshotNeo documentation for API details:
