An alternative if you don't have a pry bar or air wedges is a chisel resting on a screwdriver handle. Then you stand on the chisel handle to raise the door.
If you're thinking of routing hinge mortices it's worth making a small jig to sit on the edge of the door and use a copy ring on the router. It can take some time to make the jig but it's quite satisfying once you're up and running.
Air wedges are great I'm sure but there's a tool that is useful for carpentry jobs and quite a few others.
You put it under the door and stand on it. In a few cases you'll need to put something on the floor to protect it.
If you don't have one you should ask Santa. I have a few in different sizes and this is my current favourite.
