MD5 Hash Generator

Generate an MD5 hash from any text — instantly and entirely in your browser.

To generate an MD5 hash, type or paste text above and the 128-bit digest appears immediately as 32 hexadecimal characters. MD5 remains useful as a fast non-cryptographic checksum for detecting accidental corruption, but it is broken for security purposes.

Frequently asked questions

Can MD5 be decrypted?

No. Hashing is one-way — there is no key that reverses it. Sites claiming to "decrypt MD5" are looking up precomputed tables of common inputs, which only works for weak or common values.

Is MD5 still safe to use?

Not for anything security-related. Practical collision attacks have existed since 2004. It is acceptable only for non-adversarial integrity checks, such as detecting a corrupted download.

How do I verify a downloaded file?

Switch the input to "A file", select your download, and paste the checksum published by the source into the verify box. A match means the content is byte-identical to what they hashed; a mismatch means you should not run it.

Is my file uploaded to check it?

No. Files are read from disk and hashed in your browser, in chunks, so even very large files never leave your device.

How to use the md5 hash generator

  1. 1Choose the hash.
  2. 2Enter or paste your text to hash.
  3. 3Select your file — the file stays on your device and is never uploaded.
  4. 4Enter or paste your verify against (optional).
  5. 5Turn "Uppercase hex" on or off as needed.
  6. 6Press Run, then download the result when it is ready.
