As Instagram's new video functionality took off so did the need to embed those videos into blogs and websites. At least three sites (and we're sure more will start popping up) now offer quick, easy — and free — methods of generating Instagram embed codes for videos. All you have to do is paste the Instagram URL into a box, and click the generate button get an embed code.
Two of the sites use the same "Embed Instagram" name but have different URLs.
The second Embed Instagram works basically the same way except you can manually select videos or photos, pre-select the size (640 x 640, 320 x 320 or custom) and, for videos, choose whether to use HTML5 or flash for non-HTML5 pages.
InstaEmbed generates embed code for videos only. But you have options to choose HTML5 or flash, as well as media size (640 x 640 or 320 x 320). It's probably best to try all three to see which one works best for your blog or website.
