About the MD5 hash

MD5 (Message Digest 5) produces a 128-bit hash, usually written as 32 hexadecimal characters. Designed in 1991, it became the default checksum of the early web, and it is still what countless download mirrors, package archives and legacy systems publish next to their files. If a site gives you an MD5 checksum, this MD5 hash generator lets you compute the same value from your copy and confirm the two match.

It is important to be clear about what MD5 is for today. MD5 is cryptographically broken: researchers can deliberately construct two different inputs with the same MD5 hash, so it must never be used for passwords, digital signatures or any security decision. What it remains perfectly good at is accidental-corruption detection — verifying that a download completed correctly, that two files are identical copies, or that a backup matches its source. For anything security-sensitive, use the SHA-256 generator instead.

Text and file input, fully local

Type text into the box for an instant digest, or drop in a file — large files are read in streamed chunks so the page stays responsive even on files hundreds of megabytes in size. Every calculation happens inside your browser; there is no server on the other end reading your data. To check the result against a published checksum, paste both into the hash compare tool.

§ Frequently Asked Questions

Is my file uploaded when I generate an MD5 hash?
No. The MD5 hash is computed entirely in your browser using JavaScript. The file never leaves your device.
Is MD5 still safe to use?
MD5 is safe for detecting accidental corruption, such as verifying downloads and comparing file copies. It is not safe for passwords, signatures, or any security purpose, because collisions can be created deliberately.
How long is an MD5 hash?
An MD5 hash is 128 bits, normally displayed as 32 hexadecimal characters.
Can I reverse an MD5 hash to get the original text?
No. MD5 is a one-way hash function. The original input cannot be recovered from the hash, although short common inputs may be found in precomputed lookup tables.
