Verify a download or check file integrity by computing its SHA-1, SHA-256 and SHA-512 hashes at once. The file is read locally with the browser's Web Crypto API and never uploaded, so even large or sensitive files stay on your device.
Your files are processed securely in your browser and are not uploaded to our servers.
File Hash Calculator runs locally using your browser's built-in cryptography, so passwords, keys and hashes are never uploaded or logged.
No — hashing uses the browser's Web Crypto API entirely on your device.
SHA-1, SHA-256 and SHA-512.
Yes, within your browser's memory; very large files may take a moment.
