Tumblr Tools

Grabbing lots of images from Tumblr is not easy, which is why relying on a specialized app for this purpose is recommended. There are a fair number of them to choose from, and the open-source app presented here is certainly an interesting option.
Tumblr Tools isn’t just a simple image downloader, however, as it also enables you to gather some basic stats about blogs, as well as extract and save tags. It is very easy to use, and it even allows you to download only new images from each blog.

Save images from any Tumblr blog easily

Most users will probably get this app for its image downloading feature, as it can save you a lot of time. However, no filtering options are available, so it is only useful if you want to grab every picture posted on a particular blog, although you can exclude certain extensions and photosets.
Once you have downloaded everything, Tumblr Tools will only save new images when the blog is scanned again at a later date. You can even specify which versions of the pictures should be saved.

Extract useful blog stats and post tags

This utility can do more than just download images, as you can enter a blog’s URL and view how many photo, text, video, answer, chat, audio, link and quote posts it contains.
Additionally, Tumblr Tools can extract all the tags that are used in blog posts and export them locally to a TXT or CSV file.

Small, intuitive utility that can help you grab content from Tumblr blogs

When all is said and done, Tumblr Tools is a very simple app, but it can be very helpful if you frequently need to save images from Tumblr. It also allows you to extract stats and tags, which is certainly useful.
The application is very novice-friendly, so first-time users should not have any problems. The UI is quite rudimentary, however, though its layout is straightforward enough.
