Change text to uppercase, lowercase or title case
Fix text typed with Caps Lock on, or turn a heading into Title Case, without retyping it. The conversion runs on your own device.
Your text is processed on this device and never uploaded. We don't see, store or log anything you type.
How it works
- Type or paste your text into the box.
- Tap UPPERCASE, lowercase, Title Case or Sentence case.
- Tap Copy and paste the result where you need it.
Why convert case here
Your text stays on your device: nothing is uploaded or saved. Accented letters such as é, ß and ı are converted with the correct rules for each language.
Which case to use
Title Case capitalizes every word ("Annual Sales Report 2026"), useful for headings. Sentence case capitalizes only the first letter of each sentence, which reads more naturally for longer text. UPPERCASE suits short labels; in running text more than 5–7 words in capitals is harder to read.
Good to know
Title Case here capitalizes every word, including small words such as "and" or "of"; some style guides keep those lowercase, so check headings that must follow a style guide. Scripts without capital letters, such as Arabic, stay unchanged.
Frequently asked questions
Can I undo a conversion?
Converting to lowercase and back can't restore the original mix of capitals, so keep a copy of the original text if you need it.
Does it work on long text?
Yes. Whole documents convert instantly, because everything runs on your device.
Is my text uploaded?
No. The conversion happens in your browser and nothing is stored.
