About this tool
Different platforms and contexts need different text casing — title case for headlines, snake_case for URLs and code, UPPERCASE for emphasis sparingly.

Use cases
Title case for blog headlines and ad copy. snake_case and kebab-case for slugs, file names, and CSS classes.
Sentence case reads most naturally for body copy and social posts.
Pro tips
- Title case tools may not capitalize small words (a, the) — review output.
- Never use ALL CAPS for full paragraphs — it reduces readability.
