Swap Case
Swap uppercase letters to lowercase and lowercase letters to uppercase instantly in your browser.
Letters switch case. Punctuation, symbols, spaces, and numbers stay exactly the same.
Common swap case workflows
Swap Case is handy when text accidentally arrives in the wrong casing or when you need a fast transformation before a broader cleanup pass.
Fix or test text casing
Flip a pasted paragraph here, then move to the Case Converter if you need a specific style like camelCase, snake_case, or lowercase.
Prepare headlines and titles
After swapping case, use the Title Case Converter to polish a headline or the Slug Generator to create a URL-safe version.
Check writing length
If you are editing a shortened excerpt or label, verify it with Word Counter or Character Counter before publishing.
What this tool does
Use Swap Case when you need to fix accidental caps lock text, quickly test a formatting change, or flip the case of copy without changing punctuation, symbols, or numbers.
How to use it
- Paste or type the text you want to transform.
- Load the example or review the live preview and swapped-case counts.
- Copy the result and continue with related case or title tools if needed.
Privacy note
Swap Case runs locally in your browser. ClearUtils does not upload or store your text.
FAQ
Does swap case change punctuation or numbers?
No. Swap Case only changes letter casing and leaves punctuation, spaces, symbols, and numbers untouched.
When should I use Swap Case instead of Case Converter?
Use Swap Case when the source text already has the right characters but the wrong casing. Use Case Converter when you need a specific output style such as camelCase, snake_case, or lowercase.
Does this tool upload my text?
No. Swap Case runs locally in your browser and does not send pasted text to ClearUtils servers.
