Contracciones en inglés: I'll, don't, can't y las demás

No son «inglés informal»: son inglés normal.

En la conversación real, los auxiliares casi siempre se contraen. Usar contracciones hace que suenes natural y fluido; no usarlas suena rígido y artificial.

Pero no empieces por ahí. Primero se aprenden las formas completas, porque te ayudan a ver la fórmula con claridad.

La regla: Se junta el auxiliar con el sujeto o con not, y el apóstrofo ocupa el lugar de las letras que se quitan: I will → I'll, do not → don't.

was not / were notwasn't / weren'tIt wasn't me.
could not / would notcouldn't / wouldn'tI couldn't sleep.

Ojo con I'd: puede ser I would o I had (I'd love → would; I'd already left → had). Y 's puede ser is o has: She's tired (is) / She's gone (has). El verbo que sigue te dice cuál.
