What is the maximum amount of text I can format?

Frequently Asked Questions

Is my text uploaded or stored on any server?

No. All string cleanups, case conversions, and regex find-and-replace executions run 100% in your local browser memory (RAM). Your sensitive notes, passwords, and code never leave your device.

How does the Title Case algorithm handle small words?

Our Title Case converter follows smart grammatical rules (AP/Chicago style) by capitalizing all major words while keeping articles, prepositions, and conjunctions (like 'a', 'the', 'in', 'and', 'for') lowercase unless they begin the sentence.

Can I process large files with tens of thousands of lines?

Yes. Built on modern JavaScript string primitives and optimized regular expressions, the engine easily transforms documents of 50,000+ lines in milliseconds without freezing your browser.
