Frequently asked questions

Does it work with accented characters?

Yes, accents and special characters from other languages are preserved correctly.

Can I undo a conversion?

Paste the original text back in, or use Ctrl+Z inside the text box before leaving the page.

Is there a character limit?

No fixed limit — the tool handles long texts fine since everything runs in your browser.

Does Title Case follow editorial style rules (not capitalizing prepositions)?

No — it capitalizes every word equally. To follow a specific style guide that skips capitalizing short articles and prepositions, you'll need to adjust it manually after conversion.

Can I convert several lines at once?

Yes, the conversion applies to the entire text pasted into the box, including multiple paragraphs.
