About the Case Converter hub
Case Converter is one page with a Target case control for lowercase, UPPERCASE, Sentence case, Title Case, camelCase, PascalCase, snake_case, kebab-case, and CONSTANT_CASE. Dedicated URLs still exist for search and sharing; this hub is for switching styles without changing the path.
Your input is kept while you change Target case. Load example fills a sample. Nothing is uploaded. Open a dedicated converter when you want that style’s URL in a bookmark or an ad.
Related: Slugify for URL-safe strings with accent folding, Find & Replace for literal edits.
The hub URL is /tools/case-converter and must stay that way. It does not replace the dedicated pages for inbound links. If you only ever need one style, bookmark the dedicated converter instead.
