Frequently asked questions

Is my file uploaded anywhere?: No. Hashing runs entirely in your browser using the Web Crypto API (plus a local MD5 implementation) — your files never leave your device.
Why is MD5 included if it's not secure?: MD5 and SHA-1 are no longer considered cryptographically secure, but they're still widely used for checksums and verifying file integrity, which is why they're included alongside the stronger SHA-256 and SHA-512.
How does the compare field work?: Paste an expected hash and the tool automatically detects which algorithm it matches by length, then shows a green "Match" or red "No match" badge.
Is there a file size limit?: There's no hard limit, but very large files take longer since they're read and hashed entirely in your browser's memory.
