Aviary is an online image editor that proposes a full range of tools.
I use it when I have simple images to edit.
I like it because it’s easy, simple, free, and in the cloud, so I’ve access to all my creation whatever device I use.
The aviary chrome extension is very basic, with a simple click it capture the current page and opens aviary for further editing.
If you have to do such action, I highly recommend you to install it.
I use it a lot.
If you want to try it, just follow the link.
