To remove existing posts from your blog, choose the blog from the account menu at the top of the dashboard, then:
- On the web: Click the gear icon at the bottom of the post you want to remove, then choose "Delete." If you want to remove a large number of posts, we recommend using the Mass Post Editor, which you can access on the right side of the page or via tumblr.com/mega-editor/blogname. Having trouble finding a specific post? Try using your blog's Archive (blogname.tumblr.com/archive).
- On mobile: Tap the trash can icon at the bottom of the post you want to remove, then choose "Delete."
Just a quick note: when you delete a post from your blog, it will not delete any reblogs of that post that others have made.
