Thanks for this.

I use it with this command on Mac to copy the output in my clipboard:
data-uri file.img | pbpaste

nice for server side compression

what do you think about this pure javascript version http://www.revolunet.com/static/drop.html ?

@revolunet: There are a number of websites/services that will do it, I specifically wanted something that didn't make me find one of them, or open a browser :)

This is rad. So simple yet so effective.

I've put it togeter to change image links in HTML page with data URI.

Thanks a lot for this.

what about SVG? this don't work.

how to use this

@santosh-burada ....sorry for a reply a year late....do:
