MD5 Hash Generator

100% Free

Generate MD5 hashes from any text — checksums, fingerprints, and legacy compatibility. 100% client-side.

Real-time
Client-Side
RFC 1321
⚠️ Not Cryptographically Secure

MD5 is collision-vulnerable — use it for checksums and fingerprints, not for security. For password storage, use bcrypt; for integrity, use SHA-256.

Output case:
MD5 Hash 128 bits · 32 hex chars
Type something above…

  2. 2 Watch the 32-character MD5 hash update in real time
  3. 3 Toggle output case between lowercase and UPPERCASE
  4. 4 Click Copy to grab the hash to your clipboard

Features

  • Real-time hashing as you type
  • Lowercase and uppercase output
  • Handles UTF-8 (Unicode) input correctly
  • 32 hex characters / 128-bit digest per RFC 1321
  • 100% client-side — your input never leaves the browser

Why it Matters

MD5 is everywhere. Even though it's no longer secure for cryptographic use, it remains the de facto standard for file checksums, ETag-style content fingerprints, and legacy API contracts. A reliable, instant MD5 calculator saves devs from spinning up a Node REPL or finding the right CLI flag.

Use Cases

File Checksums

Verify a download matches the publisher's MD5

ETag / Fingerprint

Generate cache-busting fingerprints for assets

Legacy API Sign

Match older HMAC-MD5 signing schemes

Frequently Asked Questions

Is MD5 secure?
Not for security — MD5 has known collision attacks since 2004. Use it for non-security checksums and fingerprints. For passwords use bcrypt; for integrity use SHA-256.
Why is my MD5 different from another tool's?
Most likely a Unicode encoding mismatch. We encode input as UTF-8 (the modern standard). Older tools sometimes use latin-1, producing different bytes for non-ASCII characters.
Can I MD5 a file?
This page hashes text only. For files, use the Hash Generator (multi-algorithm) or run `md5sum file.bin` on Linux/Mac.
Why is the output 32 characters?
MD5 produces 128 bits = 16 bytes = 32 hex characters. The length is fixed regardless of how much input you hash.
