Although most of these tools require a subscription or an installation, the Insta Profile Pic Zoom & Save app is a free alternative. The app requires only 3MB of space, and can be downloaded on a PC or smartphone.

A profile photo downloader is a useful tool, and can allow you to view your profile photos in full quality. In fact, it is legal to do so, provided that you don't repost or redistribute the content.

Reelit is a web-based app that makes it easier to Instagram DP download. Instead of downloading an Instagram app, however, you will need to provide your email address. Once you confirm this, you will receive an email with the download link. You can then download the DP in any size and resolution. As long as you follow the instructions, you should be good to go.

You can use other similar services, but you won't have the same level of control as Reelit. Some of these tools will only let you download HD DP's, while others will only download the most basic content. Others will have ads that clutter up your screen. And some will require you to sign up for a free account.

But if you don't care about the free version and are looking for a more powerful dp downloader, there are other options.
