Case Converter

Fix the case without retyping anything

Text arrives in the wrong case constantly. A heading gets pasted in as SHOUTING CAPITALS, a CSV export comes back entirely lowercase, a colleague sends a paragraph where caps lock was on for the first half. Retyping it is tedious and introduces typos; this converter rewrites the capitalisation in one step and leaves the words themselves untouched.

Several conversions are available because different contexts want different conventions. Headlines often use Title Case, body text uses Sentence case, and a database import might need everything folded to lowercase so that comparisons work consistently.

Changing the case of your text

1. Paste your text into the box above.
2. Pick the case you want: UPPERCASE, lowercase, Title Case or Sentence case.
3. The converted text appears immediately.
4. Read it through — automatic Title Case does not know that “iPhone” and “NASA” are special.
5. Copy the result and paste it where you need it.

Available conversions

• UPPERCASE — every letter capitalised, for headings, labels and acronyms.
• lowercase — everything folded down, useful for normalising data, tags and email addresses.
• Sentence case — capitalises the first letter of each sentence and leaves the rest alone.
• Title Case — capitalises the significant words, the usual style for headlines and article titles.
• Converted on the server — your text is sent to the server and converted when you click the button.
• Punctuation preserved — only capitalisation changes; spelling, spacing and punctuation stay exactly as written.

Everyday uses

• Rescuing a paragraph typed with caps lock left on.
• Converting a headline to Title Case to match a publication’s style guide.
• Normalising email addresses or usernames to lowercase before importing them.
• Toning down marketing copy that arrived in ALL CAPS.
• Tidying product names and category labels in a spreadsheet export.
