MD5 Generator
Generate MD5 (128-bit) hashes from text or files.
What is MD5?
MD5 produces a 128-bit (32 hex character) hash from any input. The same input always produces the same hash. Even a tiny change in input produces a completely different hash.
MD5 example
hello → 5d41402abc4b2a76b9719d911017c592
Security warning
Do not use MD5 for security. It's vulnerable to collision attacks and should not be used for passwords, signatures, or certificates. Use SHA-256 or stronger for security purposes.

Frequently Asked Questions
What is MD5?
MD5 (Message Digest 5) is a 128-bit hash function that produces a 32-character hex string. It was widely used for checksums and password storage.
Is MD5 secure?
No. MD5 is cryptographically broken — collisions can be generated in seconds. Never use MD5 for passwords or security. Use it only for non-security checksums.
What is MD5 used for today?
File integrity checks (detecting accidental corruption), cache keys, and legacy compatibility. Not for security.
Can I reverse MD5?
No. MD5 is one-way. However, common inputs can be looked up in rainbow tables, so weak passwords hashed with MD5 are easily cracked.
Is it free?
Yes. Everything runs in your browser.
