About Checksum Verifier

Compute and verify checksums (such as MD5 and SHA-256) for files or text to confirm integrity. Compare a downloaded file’s hash against the publisher’s value to detect corruption or tampering.

How to use

  1. Select a file or paste text.
  2. Choose the hash algorithm (e.g. SHA-256).
  3. Compare the generated checksum against the expected value.

Frequently asked questions

Does my file get uploaded?
No — hashing runs in your browser via the Web Crypto API, so the file never leaves your device.
Which algorithm should I use?
Prefer SHA-256 for integrity checks; MD5 is offered for compatibility but is not collision-resistant.
