Preheat your oven to 350°F (175°C).
In a mixing bowl, combine crushed pretzel crisps and melted butter.
Press the pretzel mixture into the bottom of a 9x13 inch baking dish.
Bake the crust for about 10 minutes until lightly golden, then cool completely.
In a separate bowl, beat softened cream cheese and powdered sugar until smooth.
Fold in the whipped topping gently until combined.
Spread the cream cheese mixture over the cooled pretzel crust.
In a bowl, mix chopped strawberries and strawberry preserves together.
Top the cream cheese layer with the strawberry mixture evenly.
Chill the completed dip in the refrigerator for at least 2 hours before serving.
