Upper Case Generator
Turn any text into UPPERCASE, Title Case or Sentence case in one click, then copy it straight into your document or post.
Four cases, one click
Upper case capitalises every letter. Lower case removes every capital. Title case capitalises the first letter of each word and leaves the rest lower. Sentence case capitalises only the start of each sentence, which is what most style guides call the default for body text.
Where upper case actually helps
Text arrives in the wrong case from surprising places. Headlines pasted out of a design file, spreadsheet exports that shout in all caps, OCR output from a scanned page, and captions typed with caps lock on by accident. Retyping is the slow fix and the one that introduces new typos.
Title case is the trickiest of the four, because proper style rules for English say short prepositions and articles stay lower unless they begin or end the title. This tool capitalises every word in title case, which suits headings, buttons and most web interfaces. For a book or article title that must follow a specific house style, review the result before publishing.
Careful with acronyms
Lower case conversion will flatten acronyms such as NASA into nasa and proper nouns into common words. That is the nature of the operation rather than a bug. If a paragraph mixes acronyms with prose, convert it first and fix the handful of acronyms afterwards.
All caps and readability
Long stretches of upper case text read slower, because every letter has the same rectangular outline and readers lose the shape cues they use to recognise whole words. Use upper case for short emphasis, labels and acronyms. For anything a person has to read rather than scan, sentence case wins.
Upper Case Generator FAQ
Does the conversion keep my paragraphs
Yes. Line breaks, spaces and punctuation are preserved exactly. Only the case of the letters changes.
Is there a length limit
No limit is enforced. The text is processed in your browser, so a few hundred thousand characters will still convert instantly.
Which should I use for headings
Title case is the common convention for headings and buttons on the web. Sentence case is the convention in many style guides for article titles and body copy.
