When to use uppercase
Uppercase draws the eye, so it works well for short headings, acronyms, product labels and calls to action. Use it sparingly in body text, though: long runs of capitals are measurably slower to read because every word becomes the same rectangular shape, and online they can read as shouting.
Uppercase without losing the original
Because the tool keeps your input alongside the output, you can generate an all-caps version for a heading while keeping the normal-case original for the body. Need to undo an all-caps block instead? Use the sentence case converter to restore natural capitalisation.
