Chrome for Android now lets you download videos and web pages for offline viewing
Here’s how it works: the update brings a download button to the menu bar (next to the bookmark button), and clicking it when you’re on a web page or viewing a video initiates the download. Once the content is downloaded, you’ll be able to view it without an internet connection. There’s also a dedicated “Downloads” section that lets you view all the media you’ve downloaded.
