Case converter: uppercase, lowercase, title case

A case converter for text you would rather not retype

This case converter changes the capitalization of any text in one click: uppercase to lowercase, lowercase to uppercase, sentence case, or a capital on every word. It also strips accents, makes URL slugs and tidies stray spaces.

It saves retyping when:

  • you typed a whole paragraph with Caps Lock on;
  • a heading or a surname has to be in capitals;
  • a list of names pasted from a spreadsheet mixes SMITH, smith and Smith;
  • you need a web address or file name without accents or spaces;
  • text copied from a PDF or an email is full of double spaces.

How to convert case

  1. Type or paste your text in the “Type or paste your text here” box.
  2. Click a button: “UPPERCASE”, “lowercase”, “Sentence case”, “Capitalize Each Word”, “iNVERT cASE” or “aLtErNaTiNg”.
  3. Then, if needed: “Remove accents”, “url-slug” or “Clean up spaces”.
  4. Check the result and the character count, then click “Copy”.
  5. “Undo” brings back the text as it was before the last change. “Clear all” empties the box.

Accented letters keep their accent in capitals (é becomes É). “Remove accents” turns é into e and ñ into n. “url-slug” replaces anything that is not a letter or a digit with a hyphen, one slug per line. “Clean up spaces” reduces runs of spaces to one, trims each line and keeps a single blank line where several follow each other.

Title case, sentence case: which one do you need?

Sentence case capitalizes only the first word of each sentence. The button lowercases everything, then puts a capital after a period, an exclamation or question mark, an ellipsis or a line break. An abbreviation ending with a period counts as a sentence end: at 9 a.m. on monday becomes At 9 a.m. On monday.

Title case capitalizes the main words and leaves short words such as “of”, “the” or “and” in lowercase: The Lord of the Rings. Used as a title case converter, “Capitalize Each Word” capitalizes every word: The Lord Of The Rings. Lower the small words by hand. The button suits lists of names well.
