What is a text case converter?

A text case converter is an online tool that transforms text between different letter cases such as uppercase (ALL CAPS), lowercase (all small letters), title case (First Letter Of Each Word Capitalized), and sentence case (First letter of each sentence capitalized).

How do I convert text to uppercase?

Simply paste your text into the input field and click the 'UPPER CASE' button. Your text will instantly be converted to all capital letters. You can then copy the result or download it as a text file.

Is this text case converter free to use?

Yes, Convert Case Pro is completely free to use. There are no limits on the amount of text you can convert, no registration required, and no hidden fees.

Title case is a capitalization style where the first letter of each major word is capitalized, while minor words like 'a', 'an', 'the', 'and', 'or', 'but', etc. remain lowercase unless they are the first word.

Can I upload a text file to convert?

Yes, you can upload .txt files directly to the converter. Click the upload button, select your file, and the contents will be loaded into the input field for conversion.
