What is a JPG-LARGE file?

A JPG-LARGE file is a JPEG image created by Google Chrome when a user downloads a large-sized image from Twitter. It is saved in the standard JPEG format as a .JPG file, but with the custom .jpg-large file extension.

Twitter is a social networking site that allows users to post "tweets" containing text, images, and videos. Images uploaded to Twitter by users are hosted on its media server so they can be accessed and viewed again by that same user or by other Twitter users.

As Twitter users view an image in the Chrome web browser, they can right-click the image and select Open Image in New Tab to open the image in a separate browser tab. When opening a Twitter-hosted image in a new Chrome tab, the URL may look something like this:


If a user downloads the image from the URL, Chrome may save it with a JPG-LARGE file extension, creating a FHKU-pZXsAIQfKH.jpg-large file.

NOTE: While Chrome may use the JPG-LARGE file extension, the web browser more commonly adds the .JPG_LARGE extension.

What is the difference between JPG-LARGE and JPG files?

Despite the different extensions, JPG-LARGE files are normal JPG files. The reason the file extensions are different is due to the large size attribute Twitter adds to the image URL to display the appropriate image size to the user, which results in a URL ending with .jpg:large.

Then, when a user downloads the image from the URL ending with .jpg:large, Chrome changes the colon to a hyphen since filenames cannot contain colons. The resulting downloaded file is a JPG-LARGE file.

Twitter now uses the following URL structure to prevent the creation of JPG-LARGE files:
