FAQ
Is MD5 still useful?
Only as a fast integrity check against accidental corruption, not against tampering.
Why does MD5 differ from SHA-256 for the same file?
They are different algorithms with different output lengths and collision resistance.
Is the file uploaded?
No.
Files never leave your device
Processing happens in your browser using the File API, WebAssembly and Web Workers. There is no upload endpoint.
