How to generate an MD5 hash

  1. Stay on the Text tab and type or paste content — the MD5 updates live.
  2. Or switch to File and drag in a file to hash its exact bytes.
  3. Toggle Uppercase output if your system expects capitals, then copy the result.

What MD5 is good for — and what it is not

MD5 produces a 128-bit, 32-character hexadecimal digest and is fast to compute, which is why it is still everywhere: verifying that a download completed without corruption, spotting duplicate files by comparing digests, generating cache keys, and matching checksums published alongside legacy software. Those are exactly the jobs MD5 is fine for. What MD5 is not safe for is security. It has been cryptographically broken for years — attackers can deliberately construct two different inputs that share the same MD5 hash (a collision), so it must never be used for digital signatures, password storage, certificate fingerprints, or any check meant to resist a malicious party. For those uses choose a modern algorithm instead. This tool computes MD5 entirely in your browser with a small, correct RFC 1321 implementation, so your text and files never leave your device, and there is no upload, watermark, or signup.

Need a stronger or different hash?

For integrity checks that must withstand attackers, use SHA-256 or SHA-512. SHA-1 sits between MD5 and the SHA-2 family but is also broken for security. To compute MD5, SHA-1, SHA-256 and SHA-512 side by side, use the full hash generator.

FAQ

Is MD5 secure?

No. MD5 is broken for security use because practical collision attacks exist. It remains perfectly useful for non-adversarial tasks like checksums and deduplication, but never rely on it to defend against a malicious party.

What is the MD5 of the word "abc"?

It is 900150983cd24fb0d6963f7d28e17f72. You can confirm it by typing abc in the text box above.

Why is MD5 still used if it is broken?

Because it is fast and its weaknesses only matter when an attacker can craft the input. For verifying accidental corruption or finding duplicate files, that risk does not apply, so MD5 stays popular.

Is my text or file uploaded?

No. All hashing happens locally in your browser with an inline JavaScript MD5 implementation. Nothing is sent to any server.
