Tumblr images
Photos are already files. This tool is for video and audio.
By using this site you confirm you have the right to download the file you request.
Nothing for a server to do
A Tumblr photo is an image at a public address on media.tumblr.com. Your browser saves it in one gesture, at full resolution. Routing that through a server adds a wait and an advertisement and nothing else.
Where Tumblr differs from most of this list is that a single post can hold a dozen images and a video at once. Paste it here and you get the video; the images you save directly.
Frequently asked questions
Will you add image downloading?
There is nothing to add. The browser already does it better.
