Text case converter
Change capitalization while keeping your source text visible beside the result.
How to use this tool
Paste the original text into the left editor.
Choose uppercase, lowercase, simple title case, or simple sentence case. Clean spacing removes repeated spaces and excess blank lines.
Review names and abbreviations, then copy or download the result.
What the result means
Uppercase and lowercase use the browser's locale-aware text methods. The title-case button capitalizes the first letter of each detected word without applying a publisher's style guide. Sentence case uses punctuation boundaries and may not understand abbreviations. Clean spacing preserves line breaks while trimming spaces around each line.
Questions about this tool
Will it fix grammar?
No. It changes capitalization and, when requested, spacing. It does not correct spelling, grammar, or factual content.
Can I recover the original?
The original stays in the input editor until you change it or leave the page. It is not saved after a refresh.
