How can I convert an image into Base64 string using JavaScript?

I need to convert my image to a Base64 string so that I can send my image to a server.

Is there any JavaScript file for this? Else, how can I convert it?

You can use the HTML5 ` for it:

Create a canvas, load your image into it and then use toDataURL() to get the Base64 representation (actually, it's a data:` URL, but it contains the Base64-encoded image).
