MD5 checksum generator
Generate MD5 checksums for any file. MD5 is for legacy compatibility only — use SHA-256 for security. Everything runs locally in your browser.
Security notice: MD5 is useful for legacy checksums but is not secure for cryptographic purposes. For security, use SHA-256 instead.

Frequently asked questions
- What is MD5?
- MD5 (Message-Digest Algorithm 5) produces a 128-bit (32-character hexadecimal) hash. It is fast and widely supported, but has known collision vulnerabilities and should not be used for security purposes.
- Is MD5 secure?
- No. MD5 has known collision vulnerabilities that allow two different files to produce the same hash. It is suitable for verifying accidental file corruption, but not for security-sensitive applications like digital signatures. Use SHA-256 for security.
- When should I use MD5?
- MD5 is useful for verifying legacy checksums published by older software, detecting accidental file corruption, and quick integrity checks where security is not a concern.
