www.devdocs.io
This website contains fast offline and free documentation browsers for developers. It is aimed at providing manuals for just about every front-end language and library. You can search 100+ docs in one web app: such as HTML, CSS, JavaScript, PHP, Ruby, Python, Go, C, C++ and so on. It is even available as a Chrome extension or as a plugin for sublime text or Brackets.
www.photopea.com
This website allows you to edit photos online. Basically, it's like the online version of Gimp or Photoshop. You can use it anywhere as long as you have an internet connection. Also, visit PIXLR , this is awesome too.
