  2. Read the hashes for each algorithm instantly.
  3. Optionally paste an expected checksum to verify a download’s integrity.

Frequently asked questions

Which hash should I use?
Use SHA-256 for integrity and security; MD5/CRC32 are fine for non-security checksums but are not collision-resistant.
Are my files uploaded?
No — hashing runs in your browser, so even large or private files stay on your device.
