Yes. It is completely free with no sign-up and no limits.
What is SHA-256?
SHA-256 is a widely used cryptographic hash function. It turns any input into a fixed 64-character hexadecimal fingerprint. Even a tiny change to the input produces a completely different hash.
What is SHA-256 used for?
Common uses include verifying file downloads, storing password fingerprints, checksums in development, and blockchain applications.
Is my text sent anywhere?
No. The hash is computed locally in your browser with the Web Crypto API and nothing is transmitted or saved.
