Retyping a sentence just to fix its capitalisation is a needless chore, especially when you have pasted text that arrived in the wrong case entirely. The Case Converter takes whatever you paste and switches it instantly between UPPERCASE, lowercase, Title Case, Sentence case and a playful aLtErNaTiNg style, ready to copy straight back out.
How to use the Case Converter
- Paste your text into the box.
- Click the case style you want.
- Copy the converted result.
The right case for the job
Capitalisation carries meaning and tone. Headlines and titles often use Title Case, where each major word is capitalised. Body text uses Sentence case, capitalising only the first word and proper nouns. All-caps shouts for attention but is hard to read in long stretches, while lowercase feels casual and modern. Switching between them quickly is invaluable when you are repurposing text — turning a shouty all-caps heading into a readable sentence, or tidying text someone typed with caps lock on.
Tips to remember
- Title Case capitalises the first letter of every word.
- Sentence case capitalises only after sentence breaks.
- Avoid long all-caps passages, which slow readers down.
- Convert, then proofread proper nouns, which automatic case rules cannot always know.
Every conversion happens in your browser, so your text stays private and the change is instant.
