How it works
Type or paste any string; the MD5 value updates as you type so you can compare MD5 outputs quickly.
MD5 processes your text as UTF-8 bytes and produces a fixed 128-bit hash, shown here as 32 hexadecimal characters (0 to 9, a to f).
What is MD5?
MD5 maps data of any size to a 128-bit digest. The same input always yields the same hash, which is why people still use MD5 for quick file or string fingerprints—though not for modern cryptography.
Security note
MD5 is not considered safe for cryptography today. It is vulnerable to collision attacks and must not be used for passwords, TLS, or signatures. Prefer SHA-256 or SHA-3 for security-sensitive work. This page is for checksums, legacy workflows, and learning.
Common questions
- Is this MD5 generator free?
- Yes. There is no limit and no signup. Hashing runs in your browser.
- Do you store my text?
- No. Your input is processed locally in the page; nothing is sent to a server to compute the hash.
- Why is the MD5 output 32 characters?
- MD5 outputs 128 bits. Written in hexadecimal, that is 32 digits.
- Should I use MD5 for passwords?
- No. Use a modern password hash such as Argon2, bcrypt, or scrypt with a unique salt per user.
