Annuity Rollover to Roth IRA

I’m vested with my current employers annuity benefit (value around 50-70k) but may be jumping ship.

New company has no annuity. I know there is a way to roll it over into a traditional IRA but I want it to eventually be a Roth IRA.

So if I roll over to a traditional then convert to Roth will taxes be taken out of the rollover or will I need to pay the taxes when I go to file?

Also is there a maximum amount when it comes to rolling over into a traditional or converting to a Roth?
