I’ve spent a lot of time today (as it’s a public holiday) looking around for Graphic Design resources and came across this Photoshop Action from Adobe which can transform your photo/image into a sketch. It’s a very complex process with multitudes of layer adjustments and changes. There are a lot of apps online that you can use to do a similar thing but I don’t think they always do a very good job of transforming the image. Photo Manipulation is an artform all of its own and I trust Adobe for pretty much everything photo related these days.
