Online File Hash Value Generator- SHA-1, SHA-256

Generate cryptographic hash values for files directly in your browser. This online file hash generator supports SHA-1, SHA-256, SHA-384, and SHA-512 and more, allowing you to verify file integrity, detect changes, and compare file authenticity without uploading files to a server.

What Is a File Hash?

A file hash is a fixed length value generated from a file using a hashing algorithm. It acts like a digital fingerprint even a small change in the file will produce a completely different hash value. File hashes are commonly used to verify file integrity, detect modifications, and confirm that files are identical.

Example:

Original File: document.pdf

Hash (SHA-256): a3f5b2c8d9e1f2a3b4c5d6e7...

Modified File: document.pdf (1 byte changed)

Hash (SHA-256) : 7x9k2m4n6p8q1r3s5t7u9v1...

Even though the file name is the same and the change is extremely small, the hash value is completely different. This is why file hashes are reliable for detecting changes, verifying authenticity, and ensuring file integrity.
