I was banging my head trying to figure it out and use stackoverflow to save me, so here it is!

#SERVER SIDE CODE
import anvil.media
import pyheif
from PIL import Image

def convert_heic_to_png(media):
  with anvil.media.TempFile(media) as file_name:
    with open(file_name, 'rb') as file:
      heif_file = pyheif.read_heif(file)
      image = Image.frombytes(
        heif_file.mode, 
        heif_file.size, 
        heif_file.data,
        "raw",
        heif_file.mode,
        heif_file.stride,
        )
      image.save("/tmp/file.png","PNG")

      new_file = anvil.media.from_file("/tmp/file.png", "image/png", f"{media.name.split('.')[0]}.png")
      return new_file
