How the case converter works

Paste any text and switch its capitalization instantly. The tool reads your text and rewrites every letter to match the case style you choose, all inside your browser. It is built for the moments when retyping would be tedious — a paragraph typed with Caps Lock on, a heading that needs Title Case, or a list of names that should all look consistent.

The four case styles

UPPERCASE turns every letter into a capital — useful for headings, labels or emphasis.
lowercase makes every letter small — handy for tidying text pasted from mixed sources, or for a relaxed, modern look.
Sentence case capitalizes only the first letter of each sentence, following full stops, question marks and exclamation marks — the natural way most writing is formatted.
Capitalize Each Word (Title Case) capitalizes the first letter of every word — ideal for titles, headlines and headings.

Common uses

Fixing accidental Caps Lock, standardising product names or spreadsheet columns, preparing titles for articles and videos, and cleaning up text copied from emails or PDFs where the case is inconsistent.
