KeepPost - Instagram photo/video online download assistant

I don't use Instagram quite lot, but admittedly, I follow many celebrities and most of my travel inspiration comes from there. I wanted to download some photos, but saving each photo by inspecting page source was a headache.
It took good 8-9 hours for this, but I just put online a new tool to download Instagram photos and videos when you have its URL. (Drum roll, please...): KeepPost!

It's a very simple one-page site that does only one thing, and I believe it can do it perfectly well.

For anyone interested in the source code, I put the core class on Github.
