Frequently asked questions
What case styles are supported?
Common styles including uppercase, lowercase, and title case, alongside programming-oriented styles for turning phrases into consistent code identifiers.
What is this used for?
Converting a heading to title case for a document, normalizing pasted text that arrived in the wrong case, or turning a phrase into the exact identifier style a codebase's conventions require.
Does converting case change anything else about the text?
No — only letter casing changes; punctuation, numbers, and spacing are preserved exactly as you entered them (aside from what a given case style, like snake_case, specifically requires).
Is my text processed anywhere but my browser?
No. Conversion happens locally and instantly as you type or switch styles.
