Case Converter
Transform text between 8 case formats: UPPER CASE, lower case, Title Case, Sentence case, camelCase, PascalCase, snake_case, and kebab-case. Instant conversion with smart word boundary detection.
How to Use the Case Converter
Type or paste your text into the input field, then click any of the 8 case mode buttons to convert it. The result appears instantly in the output panel. Click Copy to copy the converted text to your clipboard.
The converter intelligently splits input text by spaces, hyphens, underscores, and camelCase boundaries, so it works whether your input is a sentence, a variable name, or mixed text.
What Are the Available Case Modes?
UPPER CASE converts all letters to uppercase. lower case converts all letters to lowercase. Title Case capitalizes the first letter of every word. Sentence case capitalizes the first letter of each sentence.
For programming, camelCase joins words with the first word lowercase and subsequent words capitalized. PascalCase is similar but capitalizes all words. snake_case joins words with underscores, and kebab-case joins them with hyphens — both in lowercase.
