Twitter Original-size JPEG Image

Twitter is a social media service where users can post tweets that contain text, images, and videos. For images hosted on Twitter, the social site may automatically resize the images with a JSON entity size specification to best display an image to a user.

For example, when a Google Chrome user opens the original version of an image on Twitter in a new tab, the service appends the orig specification to the image's URL, creating a URL that ends in .jpg:orig . The URL may look something like this:

https:/​/​pbs.twimg.com/​media/​FHZmGkyXsAATwn6.jpg:orig

If the user downloads the image from this page, Chrome saves the file with the .jpg_orig extension, producing a JPG_ORIG file.

Other images hosted on Twitter's media server resized to thumbnail, small, medium, and large are saved as .JPG_THUMB , .JPG_SMALL , .JPG_MEDIUM , and .JPG_LARGE files.

NOTE: Twitter changed how it specifies image sizes to prevent the creation of JPG_ORIG files. The current URL structure appears like this: https:/​/​pbs.twimg.com/​media/​FIYB3HRVQAMjdff?format=jpg&name=orig

You can open a JPG_ORIG file with any image viewer or web browser that supports JPEG images, such as Google Chrome (multiplatform) or Adobe Photoshop (multiplatform).

However, some applications that support JPEG images may not recognize the .jpg_orig file extension and not open the image. To open the files with these applications, rename the file extensions to .jpg then open them as .JPG files.
