Use Instaport to download all your Instagram photos!
If you are annoyed about Facebook acquiring Instagram, there are tons of options out there to switch to for photo sharing.
We personally recommend PicPlz.
But what about your existing photos on Instagram? There are solutions for that too.
Instaport happens to be the most popular one. It connects with your Instagram account and makes available all your photos for download through a ZIP file.
Since the news of the acquisition broke, a lot of people are using their service right now which means that the service might not be able to serve you right now. Try again on their website after a day or two!
And this is where you can apply to delete your account. Be careful though, Instagram would not let you create a new account with the same user id!
