According to TechCrunch, Tumblr gets both the image (JPEG) and the video (MOV) components of Live Photos from the iPhones that took them. If you'll recall, Apple launched the feature with the 6s and the 6s Plus. To make Live Photos work in all browsers, Tumblr converts the MOV file into an MP4 and merges it with the JPEG component using a JavaScript solution it built. The company has open sourced and released the solution on GitHub and NPM, as well.

Tumblr also hasn't forgotten all the Android users out there. In its announcement post, the website's staff mentioned that they're also working to add Live Photo support to its Android app.
