ways to save your current tumblr posts
use the wayback machine! you do have to archive each page of your blog individually but once you do all the content, including media, will be saved exactly as it was at the moment you archived it.
wordpress allows you to directly import whole tumblr blogs, and if i recall correctly it’s something both dreamwidth and pillowfort have said they are working on.

tumblthree is a great tool with a ton of functions including downloading whole blogs, only posts tagged with a certain tag, all the posts you’ve liked, etc. etc. along with being able to download every type of media hosted on tumblr (pictures, videos, audio, everything). it also has a proper GUI so no computer knowledge required beyond downloading and running programs!
if you have some knowledge of computers you can try this github solution which uses a python script to download your whole blog to your computer. even if you don’t know anything about programming or the command line they give a very good beginners tutorial on how to use it so you should still give it a shot!
if that’s still a little daunting you can try soarcodes’ tumblr post that also has a decent tutorial!
here’s another python script that should allow you to archive all the images from your blog or your likes, though it requires some knowledge of python and the command line or very very good google skills.
some notes
edit: please stop commenting on this post to self-promote your porn accounts on other sites. those replies / reblogs will be deleted or hidden.
please note that every site on this list will have pros and cons, and i haven’t listed them here since this post would be a mile long otherwise. please do your research before moving completely over to another site in case they have policies you disagree with.
also, because I see a lot of misinformed people ranting about this: deviantart does not own the art you post. some years ago hot topic stole a ton of art from DA and sold it on merchandise and people assumed that DA gave them permission to do it despite there being literally zero evidence for that claim. DA explictly states in their TOS that you retain copyright and sole license of the art you post.
and related, mastodon does not allow or condone CP or pedophilia. the people spreading this info are misinformed about what mastodon is. it is not an exact twitter clone; anyone anywhere can host a mastodon instance using their personal computer as a server, which means mastodon as a company can’t do jack shit to moderate them. what they DO is permanently block all users from every other instance from viewing or interacting with that instance, and add that instance to a publicly viewable list along with the reason for the block. please give their post about anti-abuse measures a read before making snap judgements.
