Why is formic acid stronger than acetic acid?

Acetic acid has the CH3 group, which actually makes the anion less stable because instead of delocalizing the electrons like we want, it contributes to the high electron density around the Oxygen in the anion. Formic acid does not have this CH3 group and instead just has the Oxygen single bond which is a very electronegative atom, and this Oxygen helps to delocalize the electrons and stabilize the anion, making it a stronger acid.
