It is possible to do this safely and still be able to drive on the tires, but there are some guidelines you need to follow.
If the tires are relatively new, with significant remaining tread depth (more than 7/32-inch), removing the studs will probably be worth the effort. It can be done by lubricating the studs on an inflated tire, grabbing the top of each stud with a pair of pliers, and twisting as you pull the stud out.
If the tires are older, with less remaining tread depth (less than 6/32-inch), the studs can still be removed, but the reduced tread depth will have already significantly reduced the tires* ability to bite into snow to provide good winter traction.
Once the studs have been removed, the tires must be checked for leaks due to punctures that could have occurred during stud removal. To do this yourself, spray the tread area with a window cleaner to confirm the absence of air bubbles (bubbles would indicate a leak). The tire should be rinsed with water and installed on the vehicle after setting the tire inflation to the pressure indicated on the vehicle placard.
While the tire can be used if no bubbles are seen, its air pressure should be checked daily for a few days and once a week for the first month to assure that there are no slow leaks.

The studs are not really meant to come out. It would really hard to get them out, it would take a really long time and you*d probably ruin the tire in the process.
