Exta: Pro downloader for Instagram is a free Chrome browser extension that allows users to easily download images and videos from Instagram. With this extension, users can download Instagram photos and videos with just a click of a button.

The extension automatically detects if you are viewing an Instagram photo or video and creates a link to the file in multiple formats. For images, you can choose between JPG, PNG, and GIF formats, while videos can be downloaded in MP4, AVI, 3GP, FLV, MOV, or MPEG formats. In a popup window, you will see a miniature version of the photo or video you're about to download, and by clicking the "Download" button, you can save it directly to your device.

One of the standout features of Exta is its support for mass downloading. Users can easily download a series of stories or selected posts from a specific user in one click. This means you can quickly download multiple images, videos, or stories as a zip file. To access this feature, simply click on the Exta Downloader button in the Instagram navigation menu.

It's important to note that Exta: Pro downloader for Instagram is an unofficial extension and is not affiliated with or endorsed by Instagram or Instagram Inc. It is developed and maintained independently, serving as a wrapper to the original Instagram web application to enhance its usability as a browser plug-in.
