Generate MD5, SHA-1, SHA-256 and SHA-512 hashes from any text. 100% browser-local — your data never leaves your device.

What is a hash?
A cryptographic hash function turns any input into a fixed-length fingerprint. The same text always gives the same hash, but you cannot reverse a hash back to the original text. Developers use hashes to verify downloads, store passwords safely and detect data changes.
Which algorithm should I use?
MD5 — fast, 32 characters; fine for checksums, not for security.
SHA-256 / SHA-512 — modern and secure; use for passwords and integrity.
FAQs
What is a hash generator?
A hash generator converts any text into a fixed-length string of characters (a hash) using algorithms like MD5 or SHA-256. The same input always produces the same hash.
What are hashes used for?
Hashes verify file integrity, store passwords securely, create checksums for downloads, and generate unique IDs for data.
Is my data safe here?
Yes. All hashing happens locally in your browser via JavaScript — nothing is sent to any server.
