How to make a font looking very old and out-washed in the browser

I would like to create random outwashed letters of a usual font. Let's say I want to have http://www.fontspace.com/category/washed%20out those ones but instead I use a usual font which is out-washed in the browser.

Is this possible? I mean taking a font that is out washed there the same letters are always looking in the same way.

I really would like to have the same letters but all looking a bit different. Maybe as if I would have written it by hand by myself.

Solution

No solution was really satifying.

Using an image was having the image in the background and not just on the text. So the whole background was getting the sparkles of the image.
any other way was browser incompatible or looking bad or even taking to many resources

The only way is using an existing handwritten font. Actually not the worst thing you could have.
