Compare two hashes or two strings and instantly check whether they are identical, with an optional case-insensitive mode. Perfect for validating a checksum or spotting a subtle difference. Comparison runs 100% in the browser, your data never leaves your machine.
What is it for?
- ▸ Verify a downloaded file matches its official checksum
- ▸ Confirm two MD5 or SHA fingerprints are identical
- ▸ Detect an invisible difference between two strings
- ▸ Compare values while ignoring case or spaces
FAQ
How do you verify a checksum is correct?
Paste the expected hash and your file's computed hash into the two fields: the tool immediately shows whether they match. A match confirms the integrity of the downloaded file.
Is hash comparison case-sensitive?
By default the comparison is case-sensitive, but hexadecimal hashes are often written in either uppercase or lowercase. Enable the case-insensitive option to treat them as equivalent.
Is my data sent to a server?
No, the entire comparison happens locally in your browser. No string or hash is transmitted, which guarantees the privacy of your sensitive data.
