A few websites for saving web page content

With the continuous development of the internet and the increasing number of bloggers, the amount of information online is also growing rapidly, which has led to the necessity of using many social network bookmarks to save some of the websites we've visited. In fact, apart from saving these URLs, we can also save the content of these webpages. There are now some websites that offer services to save website content, and I'd like to share a few that I know of with everyone.
