1/2" to 3/4" copper?

The water supply lines to my 2 upstairs bathrooms are 1/2" copper. I am in the process of re-doing one bathroom now, and was wondering if there is any advantage to be had by tapping off of these supply lines with 3/4" instead of 1/2", especially to the shower. Would there be any advantage (i.e. water pressure)?

Depending on how far your faucet is from the 1/2 inch piping the use of 3/4 inch piping in this situation would likely have no positive effect.

There would only be about 5 feet from the supply to the shower valve, so I also doubt any benefit. Thanks.

With water, you will not want to use a larger pipe after a smaller one. The volume coming in from the smaller pipe must fill up the larger pipe consistently in order to have the same pressure. So, the short of it is, keep the 1/2" if that is what is leading up to your appliance.
