There are more ways to save a web page for offline reading than you can imagine. Some ways are better than others, but your way is the best way.
It’s incredibly easy to save web pages on desktop and laptop computers – It’s a built-in function in most web browsers. Well, at least the major ones.
It’s not so easy on mobile devices such as smartphones and tablets. With limited storage space, mobile web browsers leave out that function.
Both of these services allow you to save more than just web pages. They support videos and images, along with just about any type of file you can download. You can access these services from any device.
Some websites, like this one, allow you to subscribe for updates. Some send summaries (like this one) and some send complete articles.
The problem, for website owners, is that they want you to visit their websites. Sending complete articles negates that effect.
I know Google Chrome and Mozilla Firefox let you save web pages as files on desktops and laptops. I don’t know about other web browsers because I don’t use any others. I’ve tested more than I can count on my phone, but I always end up going back to Chrome or Firefox.
There are extensions and add-ons for Chrome and Firefox that let you save web pages to the cloud. This makes them accessible from any device. I haven’t tested any but I plan to do so soon.
Probably the worst thing you can do is save a web page as a bookmark. You have to be connected to use a bookmark. Even then, the original web page can change or disappear completely. That may not matter for temporary bookmarks but not for long term storage of things like tutorials.
