About the File Hash Generator

Generate cryptographic checksums for any file using the native Web Crypto API (SHA-1, SHA-256, SHA-384, SHA-512) plus a fast JS fallback MD5. Use these hashes to verify file integrity, detect tampering, or compare files.

What are checksums?

  • A checksum is a fixed-length string computed from the file's binary content using a cryptographic algorithm.
  • If even one byte changes, the checksum changes — perfect for integrity verification.
  • Common algorithms: SHA-256 is the industry standard for most file verification.

Frequently asked questions

What hash algorithms are supported?

SHA-1, SHA-256, SHA-384, SHA-512 (all from the native Web Crypto API) and MD5 via a fast JS fallback.

Is my file uploaded anywhere?

No. Hashing reads your file into memory locally. Your file never leaves your device.
