How the case converter works
Last updated 10 November 2026
Fixing capitals by hand is slow. Paste the text, pick a style and copy the result.
How it works
- Upper and lower case change every letter.
- Sentence case capitalises the first letter after a full stop, question mark or line break.
- Programming styles join the words in the text.
What each case does
Paste your text, pick a style and the result changes straight away. Each style follows a simple rule.
- UPPER CASE turns every letter into a capital.
- lower case turns every letter into a small letter.
- Title Case capitalises the first letter of each word.
- Sentence case capitalises the first letter of each sentence and leaves the rest small.
- camelCase, snake_case and kebab-case join the words into a single token, the way programmers and web addresses do.
When it saves time
Text copied from a PDF or a shouting email is often in capitals. Headings pasted from a spreadsheet may all be small. A column of names can arrive in mixed case. Instead of retyping, paste the block and convert it in one go. The tool is also handy for turning a heading into a web address, which needs lowercase letters joined with hyphens.
Where you will still need to check
A converter cannot know what your words mean. After any conversion, read the result once. Common trouble spots are:
- Names with their own capitals, such as McDonald or van der Merwe
- Acronyms that should stay in capitals, such as PAYE, UIF or SARS
- Small linking words in a title, which some style guides keep in lower case
- A full stop inside a number or an abbreviation, which can make sentence case start a new sentence by mistake
Your text stays on your device
The conversion runs in your browser. Nothing you paste is sent to a server, saved or logged, so it is safe to use on drafts and private notes. Close the page and the text is gone.
Turning a heading into a web address
Web addresses are lower case, with words joined by hyphens and no accents or punctuation. Type or paste a heading, choose the hyphen style and copy the result. It is faster than editing by hand and avoids the typos that creep in when you retype.

To tidy extra spaces and blank lines after you convert, use the text cleaner. To count words after editing, try the word counter.
Working with long text
The converter handles long pieces of text, such as a whole document or a column pasted from a spreadsheet. Paste the lot, convert it once and copy it back. If you only need part of the text changed, paste just that part so the rest stays exactly as you wrote it.
Things to watch
- Names and acronyms may need correcting after a conversion.
