MD5 Hash Generator — Free Online
Generate MD5 hashes from text instantly. Note: MD5 is not recommended for security. Use SHA-256 for cryptographic purposes. Free and private.
Generate MD5 hashes for file checksums and legacy compatibility. While MD5 is no longer considered secure for cryptographic use, it remains widely used for file integrity verification and database checksums.
🔒100% Private — Your files never leave your device. All processing runs locally in your browser.
How It Works
Type or paste text, click Generate Hashes. The tool computes SHA-1, SHA-256, SHA-384, and SHA-512 hashes using the Web Crypto API — entirely in your browser.
Hashing is a one-way function: you can generate a hash from any text, but you cannot reverse a hash back to text. This makes hashes useful for verifying file integrity, storing password fingerprints, and creating digital signatures.

Frequently Asked Questions
MD5 is fine for checksums and non-security purposes. For passwords and security, use SHA-256 or SHA-512 instead — MD5 is vulnerable to collision attacks.
