Frequently asked questions
- Are my files uploaded to a server?
- No. This tool runs entirely in your browser using JavaScript — your files never leave your device.
- Which hash should I use?
- SHA-256 or SHA-512 for anything security-related. MD5 and SHA-1 are broken for security but still useful as checksums.
