Replace Parentheses
Enter text, choose literal replacements for opening and closing parentheses, and review the result in your browser.
A QUICK WALKTHROUGH
How to use this tool
- Enter up to 100,000 characters.
- Choose replacement text and whether to include fullwidth parentheses.
- Replace the selected parentheses locally, then copy the result.
Literal character replacement
Opening and closing ASCII parentheses are replaced independently with the exact text you enter. Replacement text is literal; it is not interpreted as a pattern or markup.
Optional fullwidth support
Enable fullwidth mode to replace （ and ） alongside ASCII parentheses. Other brackets, whitespace, line breaks, and all surrounding content remain unchanged.
Local and bounded
Input is limited to 100,000 UTF-16 characters. Processing and copying stay in this browser.
GOOD TO KNOW
Common questions
Does it remove the text inside parentheses?
No. Only the selected parenthesis characters are replaced; the content inside remains.
Can replacement text contain brackets or symbols?
Yes. Replacement values are inserted literally, including brackets, spaces, and symbols.
Are fullwidth parentheses changed?
Only when fullwidth mode is enabled. Otherwise （ and ） remain unchanged.
