Use SHA-256 for anything security-related. MD5 and SHA-1 are cryptographically broken — practical collision attacks exist — so limit them to cache keys and checksums against accidental corruption. Passwords need a slow, salted algorithm such as bcrypt or Argon2, never a raw SHA digest.

Frequently asked questions
Which hash algorithm should I use?
SHA-256 for anything security-related. MD5 and SHA-1 are cryptographically broken — practical collision attacks exist — so limit them to non-security uses like cache keys and checksums against accidental corruption.
Can a hash be reversed?
Not mathematically. But common passwords are trivially found in precomputed rainbow tables, which is why passwords must be hashed with a slow, salted algorithm such as bcrypt or Argon2 rather than a raw SHA digest.
Are my files uploaded to a server?
No. Every conversion runs inside your own browser using JavaScript and WebAssembly. Your files never leave your device, which means there is nothing for us to store, read, or leak.
