Palindrome Checker — Does It Read the Same Backwards?

About the Palindrome Checker

A palindrome reads the same forwards and backwards — like level, racecar, or the phrase A man, a plan, a canal: Panama. This checks any word, phrase or number instantly and tells you yes or no. It's handy for word games and puzzles, homework and language exercises, choosing memorable names or codes, and settling the occasional "is this actually a palindrome?" debate.

How it works

The tool compares your text to its reverse — want to see that reversed text itself rather than just a yes/no match? Try the Text Reverser. With the ignore case and punctuation option on (the usual way palindromes are judged), it first lowercases the text and removes everything that isn't a letter or digit — so spaces, commas and capitalisation don't count — then checks whether the cleaned string equals its reverse. That's why A man, a plan, a canal: Panama registers as a palindrome. Reversal is done by Unicode code point, and an empty input isn't treated as a palindrome.

Assumptions and behaviour

With ignore case and punctuation on, only letters and digits are compared; spaces and symbols are ignored — the standard definition for phrase palindromes.
With it off, the check is strict and exact: every character, space and capital must mirror.
Numbers work too — 12321 is a palindrome.
An empty box is reported as "type something," not as a palindrome.

Limitations

The ignore-punctuation mode keeps only A–Z and 0–9. Accented and non-Latin letters are stripped along with punctuation, so a palindrome in another language or script may be misjudged. Turn the option off for an exact character-by-character check that respects those characters.
It checks character-level palindromes, not word-level ones (phrases that read the same word-by-word backwards).
It's a yes/no check; it doesn't find or suggest palindromes within a longer text.

Frequently asked questions

Is this palindrome checker free?

Yes — free, no sign-up, no limits, runs in your browser.

Does it ignore spaces, punctuation and capitals?

With the 'ignore case and punctuation' option on, yes — so 'A man, a plan, a canal: Panama' counts as a palindrome. Turn it off for an exact, literal check.

Can it check numbers?

Yes. Numbers like 12321 are checked the same way and register as palindromes.

Does it work for other languages?

The ignore-punctuation mode keeps only A–Z and 0–9, so accented and non-Latin letters are stripped and may be misjudged. Use the exact mode (option off) for those.

Can it check whole phrases word by word?

No. It checks character-level palindromes, not phrases that read the same word-by-word in reverse.

Is my text uploaded?

No. Everything runs locally in your browser; nothing is sent or stored.
