Your files are secure
Drop the file, read the checksums, compare. Hashing runs entirely in your browser — the file is never transmitted.
Drag & drop any file into the tool, or click Choose File to browse.
All four checksums appear instantly — MD5, SHA-1, SHA-256 and SHA-512.
Copy the hash you need and compare it against the source value — a match means the file is intact.
That's it. The file was hashed locally on your device and never uploaded anywhere.
Built for speed, privacy and reliability — on any device.
MD5, SHA-1, SHA-256 and SHA-512 from a single drop — match whatever checksum the publisher published.
One comparing glance tells you whether the file that arrived is byte-for-byte the file that was sent.
Hashing happens on your device. The file — even a sensitive one — is never uploaded to any server.
ISO images, installers, documents, archives — if it's a file, it has a hash.
Hash as many files as you need at zero cost — no account, no size anxiety, on any device.
A hash is a file's unique fingerprint. It verifies that a download completed intact, proves two files are identical, and detects tampering — the checksum a software site publishes next to its installer is there to be checked like this.
SHA-256 is today's default for verification — it's fast, universally supported and secure. SHA-512 is equally trusted. MD5 and SHA-1 still work for basic corruption checks but shouldn't be relied on for security comparisons.
Practically, no. A good hash function makes collisions astronomically unlikely — two different files producing the same SHA-256 is not something that happens by accident.
No. Hashing is a read-only calculation — the file is read, its fingerprint computed, and the file itself is left completely untouched.
The tool works in all modern browsers including Google Chrome, Mozilla Firefox, Microsoft Edge, Safari and Opera. We recommend keeping your browser up to date for the best experience.
