Case Converter
Switch text between uppercase, lowercase, title case, sentence case, and alternating case. Your work stays on this device whenever possible.
How to use Case Converter
- Choose or enter plain text typed or pasted into the editor; avoid using your only copy of important material.
- Choose the narrowest settings that match the job. Read every label and change only the settings relevant to this job.
- Run Case Converter, then wait for its status message instead of pressing the action repeatedly.
- Check the output in the application where it will ultimately be used. Save or copy the result only after that review.
What Case Converter does
Switch text between uppercase, lowercase, title case, sentence case, and alternating case. The page concentrates on this exact job, keeps the controls beside the result, and reports invalid or incomplete input instead of silently inventing an answer.
The page reads Unicode text in memory and applies the selected text rule directly. It does not create a server-side copy. For Case Converter, the operation is specifically to switch text between uppercase, lowercase, title case, sentence case, and alternating case.
Worked example
Convert “toolkitPOINT makes PDF tools.” Lowercase should be “toolkitpoint makes pdf tools.” while sentence case keeps a capital opening and final period.
How to verify the result
Read the beginning, middle, and end of the result. Punctuation, blank lines, and non-English characters are the most useful things to spot-check. The final Case Converter output should visibly match this goal: Switch text between uppercase, lowercase, title case, sentence case, and alternating case.
Important limitations
Automatic casing cannot infer brands, acronyms, names, or style-guide exceptions. Review proper nouns.
