Check a hash without sharing the data.
Generate MD5, SHA-1, and SHA-256 checksums from text or a file — processed entirely in this tab, never uploaded.
Drag any file here, or click to browse
The file stays on your device and is never uploaded

Copy and compare
Use a checksum to confirm that content matches the original.
Good to know
Does my text or file get uploaded?
No. Hashing runs locally in your browser. Your text and files never leave your device.
Which hash should I use?
SHA-256 is the strongest option here and the best general choice for verifying files. MD5 and SHA-1 remain useful when you need to compare against an older published checksum.
Can I use MD5 or SHA-1 for passwords?
No. MD5 and SHA-1 are not secure for passwords, and even SHA-256 alone is not a password-storage scheme. Use a purpose-built password hashing function such as Argon2, scrypt, or bcrypt.
Why does a tiny change produce a completely different hash?
Hash functions are designed so even a one-character or one-byte change produces a very different result. Matching hashes are useful evidence that two inputs are identical.
Can I hash an empty text value or an empty file?
Yes. Empty content has a valid, standard hash for every algorithm, so this tool generates it normally.
