sigma withdrawing but pi donating.
Both are relatively weak effects. The withdrawing deactivates overall, but the donation makes ortho and para reaction faster.
Note that fluorine is most electronegative, but the pi orbitals match better with carbon. As electronegativity decreases (F-Cl-Br-I) and withdrawing effect decreases, size increases and donating effect also decreases so all halogens are about the same.
