What is MD5 and is it still safe?
MD5 is a hash function from 1992 that turns any input into a fixed 128-bit fingerprint (32 hex characters). The same input always yields the same hash, and any tiny change produces a completely different one — which made it popular for file checksums and integrity checks.
Cryptographically, MD5 is broken: collisions (two inputs with the same hash) can be manufactured in seconds, so it must never be used for passwords, signatures or security. It survives legitimately in non-security roles — cache keys, deduplication, checksums against accidental corruption, and legacy system compatibility.
How to use

- 03Toggle UPPERCASE if you need capital hex digits.
- 04Copy the 32-character MD5 checksum.
Frequently asked questions
- Is MD5 safe for passwords?
- No. MD5 is cryptographically broken and should never be used for password storage or security purposes. It remains useful for non-security checksums and legacy system compatibility.
- Why is the MD5 hash always 32 characters?
- MD5 always produces a 128-bit digest, which is written as 32 hexadecimal characters regardless of input size.
- Is my text sent to a server to be hashed?
- No. The MD5 algorithm runs as JavaScript in your browser — your input never leaves your device.
