MD5: 128-bit hash, fast but not secure for cryptography. Used for checksums.
SHA-1: 160-bit hash, deprecated for security but still used for integrity checks.
SHA-256: 256-bit hash, part of SHA-2 family. Recommended for security applications.
SHA-512: 512-bit hash, strongest option. Used in blockchain and high-security contexts.

Expert advice from Security Expert
For any security-sensitive application, SHA-256 is the recommended minimum.
When verifying files, always compare the complete hash string, not just part of it.
All hashing happens in your browser. Your data never leaves your device.
These tips come from our team of document processing engineers with over 10 years of combined experience in PDF technology, file conversion, and digital document workflows. We've processed millions of documents and learned what works best.
For security purposes, use SHA-256 or SHA-512. MD5 and SHA-1 are still useful for checksums but should not be used for passwords or sensitive data.
No. Cryptographic hashes are one-way functions. You cannot recover the original data from a hash.
That's by design! Hashes are deterministic - the same input always produces the same output.
No. All hashing is done locally in your browser. Your data never leaves your device.
