Case Converter for Upper, Lower and Title Case
Convert text to UPPER, lower, Title, Sentence or aLtErNaTiNg case.
Fixing the case of a heading by hand is slow, error-prone work, and it comes up constantly: a headline pasted in all caps, a title typed in lowercase, a paragraph that needs to read normally again. This tool converts pasted text into uppercase, lowercase, title case, sentence case, or alternating case with one click, and the result appears in its own box, so your original text stays untouched while you compare styles.

About Case Converter
A headline arrives in ALL CAPS and needs to become a tidy Title Case Heading without you retyping it word by word. Case conversion is one of those tiny tasks that eats minutes several times a week, and this tool reduces it to a single click: paste your text, pick one of five styles, uppercase, lowercase, title case, sentence case, or alternating case, and copy the result.
Each style has a natural home. Uppercase and lowercase normalize text for comparison or cleanup. Title case is the classic heading style, capitalizing the first letter of each word. Sentence case flattens everything and capitalizes only sentence starts, which is handy for turning shouted text back into normal prose. Alternating case (tHiS kInD oF tExT) is pure playfulness, meme captions, social posts, and the occasional prank.
Nothing you paste is ever overwritten: each conversion lands in its own result box, so you're free to try all five styles on the same input and compare. One thing to know about title case: most converters capitalize every word uniformly, including short words like 'and' or 'the', whereas formal style guides have exceptions for them, treat the output as a fast draft for headings and give published titles a quick human pass.
Worked example: paste 'quarterly SALES report' and choose Title Case to get 'Quarterly Sales Report'. Choose Sentence Case on the same input and you get 'Quarterly sales report', which suits body text better than a heading.

Tips for best results
- Use sentence case to instantly tame ALL-CAPS text copied from slides, PDFs, or older documents.
- Start with title case for headings, then manually fix small words like 'and' or 'the' if your style guide requires it.
- Paste mixed content once and flip between styles freely, the input stays untouched while you compare.
- Reserve alternating case for casual posts and memes; it reads as playful, not professional.
- For code-adjacent identifiers, convert to lowercase first as a neutral starting point before adding underscores or camel humps.
