Sobre Case Converter
A case converter changes the capitalisation of text quickly. Writers use it to fix headlines typed in capitals, developers use it to rename variables and file names, and editors use it to apply consistent title or sentence case across a document. Paste your text, pick the format you need, and copy the result.
The converter supports UPPER, lower, Title, Sentence, camelCase, PascalCase, snake_case, kebab-case and CONSTANT_CASE. Programmers often need the code-style formats because variable names and file names are conventionally written without spaces. Sentence case capitalises only the first word of each sentence, which suits body copy and captions.

Preguntas frecuentes
What is the difference between camelCase and PascalCase?
Both join words together without spaces. In camelCase the first word starts with a lowercase letter, as in userName, while every later word starts with a capital. In PascalCase every word starts with a capital letter, as in UserName. Teams pick one according to their language or house style.
How do I convert text to title case?
Paste your text into the converter and choose Title Case. Each word is then given a capital first letter, which is the usual format for book, film and article titles. Check the result afterwards, because some style guides keep short words such as 'and', 'of' and 'the' in lower case.
What is snake_case and when is it used?
Snake case writes words in lower case and joins them with underscores, as in order_total. It is widely used for variable and function names in many programming languages, and for file names where spaces are best avoided. Constant case is a related format that uses capital letters, as in MAX_RETRIES.
Can I convert text to kebab-case for URLs?
Yes. Kebab case writes words in lower case and joins them with hyphens, as in spring-sale-2026. Many people find hyphens easier to read than underscores in web addresses, which is why kebab case is popular for URL slugs. Remove any punctuation before converting so that the slug stays clean.
Does changing case affect the meaning of my text?
No, changing case alters only the capitalisation of letters, so the words stay the same. However, text in all capitals is harder to read and can read as shouting, so check the tone before publishing. Be careful with names and acronyms, which may need their original capitals put back after conversion.
