What is a text case converter?

A text case converter changes the capitalization format of any text: all caps, all lowercase, title case, sentence case, camelCase for programming, kebab-case for URLs and snake_case for variable names. It is the tool you use to fix titles, prepare texts for publishing or normalize data before copying it into your code.

How to use this tool

Paste or type your text in the top area.
Click the format you want: uppercase, lowercase, title case, sentence case, camelCase, kebab-case or snake_case.
Copy the result with one click.

Difference between formats

Title Case: every main word starts with a capital letter (for article and book titles).
Sentence case: only the first letter of the sentence is capitalized (natural style).
camelCase, kebab-case and snake_case: technical formats for variables, functions, URLs and file names.

Frequently asked questions

Does the converter respect accents?

Yes. Accented letters (á, é, í, ó, ú, ñ, ü) convert correctly to upper and lower case.

Which format should I use for URLs?

kebab-case (words separated by hyphens) is the standard for friendly URLs and web file names.
