MD5 Hash Generator
Generate the MD5 hash of any text, right in your browser. 128-bit digest, 32 hex characters, nothing sent to a server.
Independently verified for accuracy
Calculator by Toolsloft ↗This tool computes the MD5 hash of whatever text you paste in. MD5 produces a 128-bit fingerprint, written as 32 hexadecimal characters, and the same input always gives the same hash. It runs entirely in your browser, so the text you type never leaves your device.
How this is calculated
The hash follows the MD5 algorithm as defined in RFC 1321: your text is encoded as UTF-8 bytes, padded, and processed in 512-bit blocks through the four MD5 rounds. Our JavaScript implementation is checked against Python's hashlib on every build, so its output matches any standard MD5 tool byte for byte.

FAQ
- Is MD5 safe for passwords?
- No. MD5 is fast and has known collision weaknesses, so it should not be used to store passwords or for security signatures. Use it for checksums, cache keys, and deduplication, not for protecting secrets.
- Why is my MD5 always 32 characters?
- MD5 always produces a 128-bit digest, and 128 bits written in hexadecimal is exactly 32 characters. The length never changes, no matter how long or short the input is.
- Does it hash the text as UTF-8?
- Yes. The input is encoded as UTF-8 before hashing, so accented letters and emoji produce the same hash you would get from any standards-compliant MD5 implementation.
