When going down a row in the Periodic Table (see figure below), the atoms get larger so the strength of the bonds get weaker, which means the acids get stronger. HBrO3 is Acid. Similarly, bromine and oxygen have 7 and 6 valence electrons respectively. What is a strong acid? In weak acid, only a part of the molecule will make ion form so the pH changes would be less than the strong acid. See here for more in-depth discussion. Weekreport 36, 2022.

The oxygen of the hydroxyl OH group shares its one electron with the central bromine atom and results in a single covalent bond. Cl is more electronegative (and smaller in size) than Br. But then, I read somewhere that $\ce{HBrO4}$ is stronger than $\ce{HIO4}$, because in this case it's electronegativity that plays the important role. So to make the structure stable and formal charge 0 there was the formation of double covalent bonds between the bromine atom and two oxygen atoms. Formic Acid HCHO2 weak acid. The other 2 oxygen forms a double covalent bond with the bromine atom completing the stability criteria. Which is the stronger acid: H2O or H3O+?
