MD5 Hash Generator
Type or paste any text and get its MD5 hash live as you type. Computed entirely in your browser, nothing uploaded.
An MD5 hash, computed as you type
MD5 turns any input into a 32-character hexadecimal fingerprint, where the same text always gives the same value. Because the Web Crypto API in your browser does not offer MD5 (it dropped it on purpose), this page ships a small, self-contained md5 function and runs it on the UTF-8 bytes of your text, so emoji and accented characters hash correctly. Nothing you type is uploaded; the whole thing happens on this page.
Use it for checksums, not for secrets
To be honest about it, MD5 is broken for security. Researchers can produce two different inputs with the same hash, so it is unsafe for passwords, signatures, or anything an attacker might try to forge. It is still genuinely useful for quick checksums, deduplication, cache keys, and matching legacy systems that expect it. When you do need to keep something safe, that is a different job: Relic is the end-to-end encrypted memory for everything you copy, masked by default and readable only by you. Hash here for free; keep the real secrets in Relic.
Frequently asked questions
What is an MD5 hash?
MD5 turns any input into a 32-character hexadecimal fingerprint. The same text always produces the same hash, which makes it handy for checksums, deduplication, and cache keys. This page computes it on the UTF-8 bytes of your text, so emoji and accented characters hash correctly.
Is MD5 secure?
No. MD5 is cryptographically broken: researchers can construct two different inputs that produce the same hash (a collision). That makes it unsafe for passwords, digital signatures, or anything an attacker might try to forge. It is still fine for non-security checksums.
Should I use MD5 to store passwords?
No, never. Beyond MD5 being broken, plain hashing of any kind is the wrong tool for passwords. Use a purpose-built password hash like bcrypt, scrypt, or Argon2, which are deliberately slow and salted. For secrets you need to keep, use real encryption, like our encrypt text tool or an end-to-end encrypted store.
What is MD5 still good for?
Quick, non-security uses: verifying a file downloaded intact, deduplicating records, building cache keys, and matching legacy systems that expect an MD5 value. For anything where forgery matters, use SHA-256 instead.
Is my text sent to a server to compute the MD5?
No. Since browsers do not offer MD5 natively, this page ships a small self-contained MD5 implementation and runs it locally, so nothing you type is uploaded.
