Case Converter

What is a Case Converter?

A Case Converter changes the letter case of your text in seconds. Paste your text, choose the conversion you want and copy the result in one click. Headlines, resume bullets and social posts can be reformatted instantly.

Which conversions are available?

• Uppercase: makes every letter uppercase for emphasis and headings.
• Lowercase: makes every letter lowercase and restores normal form.
• Title Case: capitalizes the first letter of every word for article and blog titles.
• Invert: flips uppercase/lowercase, perfect for text mistyped with Caps Lock on.

Does it support Turkish characters?

Yes. Turkish letters are handled specially: ç, ğ, ı, i, ö, ş, ü correctly become Ç, Ğ, I, İ, Ö, Ş, Ü. This keeps results consistent for Turkish content.

When is it used?

• Fixing text accidentally typed with Caps Lock on.
• Formatting headings, subtitles and resume titles quickly.
• Emphasizing quotes or slogans in uppercase.
• Standardizing case-sensitive fields like file names and form inputs.

Is my data safe?

Yes. Conversion happens entirely in your browser; your text is never sent or stored. No signup, no install and completely free.
