Okay, so here’s how to do this.
First off, go here and make sure you have Python installed. For Windows it should be the very bottom link, the x86 MSI Installer. You don’t have to do anything but install it.
Second, go here, and click “Clone or Download” (the green button on the right). Select “Download ZIP”.
Make sure you have WinRAR or 7zip or something installed that lets you extract zip files.
Next, make a folder on your desktop. I named mine “Tumblr Backup”, and in the following instructions I’m going to assume that’s what you’ve named yours as well; replace “Tumblr Backup” with whatever you name yours if it isn’t.
Drop the zip file you downloaded into Tumblr Backup. Go in and extract it; this should create a folder called “tumblr-utils-master“.
Open your Command Prompt. If you don’t know how to find that, click your start menu button and type “CMD”, which should give you this:
That frog over there is blotting out my profile name on my computer. Whatever your profile name is when you sign in (e.g. “Max” or “Snugglebuns” or “froglord69”) is going to be in that spot on the address path. If it instead says something about Windows and System 32, that’s okay, what I’m gonna tell you to do will go to the right place either way.
Next, input this command–keeping in mind that the parts in bold should be changed based on your profile name and what you named the folder on your desktop:
CD C:\Users\froglord69\Desktop\Tumblr Backup\tumblr-utils-master
There! Now you’re in the right folder! Next, enter this command, replacing the bolded bit with your own blog name:
tumblr_backup.py yourblogname
Then just…let it run! It took less than five minutes for my computer, though it will vary by processor and connection. Once it’s done, you’ll have something like this:
That “index” opens in an internet browser. It’s basically a webpage stored directly on your computer. Some pics of mine:
So…not pretty, but it’ll save the content of your posts. Hope this helps!
