How this tool works
Lowercase mode applies the browser’s Unicode lowercase mapping with the English locale. It changes letters throughout the input, including acronyms and proper names; it does not infer which words should remain capitalized. Spaces, punctuation, numbers, and line breaks are retained. The result cannot recover the original capitalization once that information has been removed.
Input and output stay in the current page. Refreshing or closing the page clears them. For very large inputs, use Run to start processing; a task that takes too long is stopped so you can change the input.
Frequently asked questions
Does lowercase mode keep acronyms such as NASA in capitals?
No. NASA becomes nasa in lowercase mode. The Preserve uppercase acronyms option belongs to sentence case and does not affect lowercase conversion.
Will converting to lowercase also remove spaces or punctuation?
No. It changes letter case only. Existing spaces, punctuation, numbers, and line breaks stay in place; use a separate cleanup tool if you want to change them.
