About Case Converter

Convert text to uppercase, lowercase and title case. Use it when you need the result without the overhead of opening a larger application. For anything important, compare the output with your source and keep the original until you are satisfied with the result.

Editorial note

Automate the mechanical part, then proofread names

Changing case is a mechanical transformation. It is excellent for normalizing pasted text or producing uppercase/lowercase variants, but title case cannot know every surname, acronym, product name or editorial style.

Use the converter to remove repetitive editing, then scan the result for proper nouns and abbreviations.

A realistic example

A list copied in ALL CAPS can be converted to title case quickly, then manually corrected for names such as iPhone, eBay or API acronyms.

When this tool is not the right fit

For publication-quality title casing tied to a specific style guide, human review is still needed.
