Is my data sent to a server?

No. All hashing is done locally in your browser using the Web Crypto API. Your text never leaves your device.

What is the difference between SHA-256 and SHA-512?

SHA-256 produces a 256-bit (64 hex chars) hash, SHA-512 produces a 512-bit (128 hex chars) hash. SHA-512 is more resistant to brute force but both are considered secure.

Why is SHA-1 included if it's weak?

SHA-1 is still widely used in non-security contexts like Git commit hashes and file integrity checks. It should not be used for passwords or digital signatures.

This tool hashes text input only. For file hashing, you would need to read the file as bytes first.
