FAQ
Does it support special characters and accented letters?
The converter handles standard ASCII letters. Accented characters (é, ñ, ü, etc.) are preserved as-is during conversion.
Can I convert only part of my text?
Yes. Highlight just the section you want to convert, then click a case button. The unselected text stays unchanged.
Is there a character limit?
No. The tool works entirely in your browser, so there's no server-side limit on text length.
