Free Palindrome Checker
Check if text reads the same backwards.
What is the Palindrome Checker?
A palindrome reads the same forwards and backwards — 'level', 'racecar', or the sprawling 'A man, a plan, a canal: Panama'. They're a favorite in word games, puzzles, and programming exercises, but checking a long phrase by eye is easy to get wrong.
This checker instantly tells you whether a word, phrase or number is a palindrome, with an option to ignore case, spaces and punctuation.

What does this tool do?
You enter text and the tool compares it against its reverse, reporting whether they match.
With the ignore option on, it strips case, spaces and punctuation first, so full phrases and sentences are recognized as palindromes rather than only single words.

Common mistakes to avoid
Expecting phrases to pass with strict matching
Fix: Turn on ignore case, spaces and punctuation for sentence palindromes.
Forgetting punctuation counts in strict mode
Fix: With the option off, commas and colons must mirror too.
Assuming numbers aren't supported
Fix: Numeric palindromes like 12321 are checked the same way.
Trailing spaces
Fix: They're trimmed automatically, but check pasted text for hidden characters.
