Alternating Case Converter
Alternating Case Converter exists to do one job well: convert letters to alternating case. All counting, matching and rewriting happens in JavaScript on the page itself, so even long confidential drafts stay in your browser. It is used most by SEO and content staff checking density and readability. Pasted rich text is reduced to plain text — formatting is not carried over. There is no account to create, no email to hand over and no cap on how often you use it.

- Handles full Unicode, so accented Latin, Cyrillic, Arabic, Chinese and emoji all count correctly.
- Works on desktop, tablet and phone — no separate app to install.
- Built to do one job properly rather than twenty jobs badly.

Frequently asked questions
- Does it handle languages other than English? — Yes — full Unicode support, so Cyrillic, Arabic, Chinese, Japanese, accented Latin and emoji are all handled properly.
- How much text can I paste in? — Tens of thousands of words is comfortable. The only real limit is how much your browser will hold.
- Can I use it offline? — Once the page has loaded, yes — the work happens locally, so a dropped connection will not interrupt you.
- Will formatting be kept? — No. Pasted content is treated as plain text, so bold, colours and links are dropped.
