Whenever I'm browsing something that I want to send to my mobile, I send it via WhatsApp web or some hard way.
I wanted a way to quickly send links to my mobile. Since we can scan QR code to open URLs, I create a page that takes a URL input and generates a QR code. And then I created a JavaScript snippet that I could add to bookmarks, so I can click that when I'm on a web page and let the bookmarklet create a QR code.
This is a super simple app and can be built with a couple of lines of code.
But I thought this might be useful for people who do not have the time to build it for themselves.
