File Hash Checker
Compute and verify file hashes (MD5, SHA-1, SHA-256, SHA-512) locally in your browser
What is a file hash?
A file hash is a unique fingerprint generated from file contents using a hash algorithm. Even a tiny change in the file produces a completely different hash, making it ideal for verifying file integrity.
How do I verify a file download?
Copy the expected hash from the download page, select the same algorithm, paste it into the verify field, and click Compare. A match confirms your download is intact.
Is my file uploaded to a server?
No, all hash computation happens locally in your browser. Your files never leave your device, ensuring complete privacy.
Which hash algorithm should I use?
SHA-256 is recommended for most purposes as it balances security and speed. MD5 is fast but not collision-resistant. SHA-512 provides the highest security for sensitive applications.
