What is Pindownloader?

Pindownloader aims to serve two main needs:

  1. Backing up your pin boards
  2. Finding the top repinned images of any board on Pinterest or any search results

Pinterest provides no way to do either of those. While it is easy to manually save all your board images, it can take forever especially if you have a lot of pins. And can you believe Pinterest does not provide any way to sort by number of repins?
