Why is MD5 still here if it's insecure?

MD5 is broken for security but useful for non-security checksums (file integrity, cache keys, dedupe). SHA-256 is the right choice when you need collision resistance.

Are the inputs uploaded?

No. Hashes are computed in your browser using WebCrypto (and a small inline MD5).

Can I hash large files?

Files load fully into memory first, so large files (>500 MB) may slow your browser. SHA-256 of a typical PDF is instant.

About Hash Generator (MD5, SHA-1, SHA-256, SHA-512)

Hash Generator computes cryptographic hashes (MD5, SHA-1, SHA-256, SHA-384, SHA-512) for any text or file. All five hashes update live as you type, or upload a file and get all of them at once for verification. Useful for verifying downloaded file integrity (compare against the publisher's published checksum), generating cache keys, hashing passwords for non-security uses, and confirming two files are identical. MD5 and SHA-1 are insecure for security purposes (collision attacks are trivial) but still useful for non-security checksums. Use SHA-256 or stronger for anything where collision-resistance matters.
