title case rules in English and Portuguese
A title is not just capitals everywhere. In English the style guides disagree on prepositions and conjunctions; in Portuguese there is no mandatory rule and editorial convention applies. The converter applies each rule so you can compare results side by side.
Over has four letters, so it is capitalized.
Prepositions stay lowercase whatever their length.
In would be lowercase in the middle, but it ends the title, so it is capitalized.
dos and do stay lowercase; A after the colon is capitalized.
Sentence case capitalizes only the first letter of each sentence. Title Case applies a style guide: content words capitalized, short articles, prepositions and conjunctions lowercase. Capitalize Each Word just capitalizes the first letter of every word and leaves the rest alone, like CSS capitalize.

Uppercase acronyms (NASA) and mixed-case brands (iPhone) are preserved by default. Ordinary proper nouns, such as city names, come out right only if they were already capitalized or are content words, which title case capitalizes anyway. Always review.
It is not mandatory. The Orthographic Agreement allows both forms in book titles (As pupilas do senhor reitor or As Pupilas do Senhor Reitor). Follow your institution convention and stay consistent.
Every letter in capitals. Some letters grow: ß becomes SS.
