MD5 Hash Generator
Runs in your browser — your data is never uploaded.
Compute the MD5 hash of any text and get the standard 32-character lowercase hex digest. MD5 is broken as a security primitive and has been for two decades — but it is still the checksum printed next to ISO downloads, firmware images, database dumps and mirror listings, so verifying one is an ordinary, legitimate job. Hashing runs entirely on your device, so whatever you paste stays with you.

How to use MD5 Hash Generator
- 1
Paste or type the text you want to hash.
- 2
Switch algorithm if you need a SHA digest instead — MD5 is the default here.
- 3
Click “Generate hash” and copy the 32-character hex digest.

Frequently asked questions
Is MD5 safe to use?+
Not for anything security-related. Practical collision attacks have existed since 2004 — two different inputs can be made to produce the same digest — so MD5 cannot prove a file has not been tampered with by someone who wanted to tamper with it. It is still perfectly good at what most people use it for: detecting accidental corruption, deduplicating files, and matching the checksum a vendor published.
Why does my browser not have MD5 built in?+
WebCrypto — the browser’s native crypto API — deliberately omits MD5 precisely because it is unsafe, so it cannot be reached the way SHA-256 can. This tool uses a compact implementation of RFC 1321 instead, verified against the RFC’s own published test vectors.
Can I use this to store passwords?+
No, and please do not. Unsalted MD5 password hashes are the single most commonly cracked thing in every breach dump, because a modern GPU tries billions per second. Use bcrypt, scrypt or Argon2, which are deliberately slow and salted.
Why is my hash different from the one on the download page?+
Almost always a whitespace difference — a trailing newline changes the digest completely. This tool hashes exactly the bytes you paste, including any newline your editor added at the end.
Can an MD5 hash be reversed?+
Not by inverting it — hashes are one-way. But short or common inputs are trivially recovered from precomputed lookup tables, which is a different thing and just as fatal if you were relying on the hash to hide something.
