I want to know how can someone download an Instagram profile picture in high resolution (like these websites: InstaDP, izoomyou, etc.) without any third-party apps or websites. These pictures can't be downloaded with the "src" attribute because it gives you a 320x320 low-resolution picture. I read some of the questions and answers from this site but those methods don't work anymore. If someone knows how to do this please write it here. Any help is much appreciated.
