Case Converter
Frequently asked questions
When is changing case needed?
Caps Lock got left on by accident – it is faster to fix the case of the whole thing than to retype the text from scratch. Headings and titles – bringing text to a consistent style before publishing. Data from an outside source – text pasted from a spreadsheet or a database is often typed in one solid case.
Why does Title Case also capitalize small connecting words?
The mode capitalizes the first letter of every word with no exceptions, so prepositions and conjunctions ("and", "in", "on") in the middle of a phrase also get a capital letter. For headings where style guides keep small function words lowercase, the result is worth checking and fixing by hand. If a capital is only needed at the start of the line, Sentence case fits.
Can the case of only part of a text be changed?
The form processes the whole text in the field. To convert only a selected fragment, paste that specific fragment into the field on its own, rather than the whole text at once.
How does the converter handle accented letters like é or ñ?
They are treated as ordinary letters and change case the same as any other, whether they come from a borrowed word like "café" or a name like "Chloé" – no separate setting is needed for them.
Do digits and punctuation stay unchanged?
Yes, the case is applied only to letters – the converter does not touch digits, spaces or punctuation marks.
Paste text, choose one of four modes and press "Convert" – text can be turned into uppercase, lowercase or sentence case all at once, with no retyping by hand.
How to change the case of text
- Paste the text. A word, a sentence or text of any length all work.
- Choose a mode. One of four radio buttons below the input field: turn the text into uppercase, into lowercase, capitalize the first letter of every word, or only the first letter of the sentence.
- Press "Convert". The result appears below the form right after clicking.
Four case modes
| Mode | Example from "hello world" |
|---|---|
| Sentence case | Hello world |
| lower case | hello world |
| UPPER CASE | HELLO WORLD |
| Capitalized Case | Hello World |
"Sentence case" capitalizes only the very first letter of the whole text, "Capitalized Case" capitalizes the first letter of every word. They are easy to mix up when only one capital word is needed at the start of a line.
What's next
After changing the case of a heading, it is convenient to build a page address from it right away with the slug generator, and check the length of the finished text with the word and character counter.
