Your files are secure
Compute MD5, SHA-1 or SHA-256 checksums for any file — verify downloads and prove files haven't changed, all locally.
Add your file — drag it into the tool or click Select File to browse.
The hashes are computed instantly: MD5, SHA-1 and SHA-256 in one pass.
Compare the checksum against the one the publisher published.
Matching hashes mean the file is intact and untampered.
Built for speed, privacy and reliability — on any device.
MD5, SHA-1 and SHA-256 in a single pass — whichever checksum you're given.
Compare your hash against the publisher's to confirm the file is intact.
Hashing runs locally — even large files never reach a server.
Hashes are that precise: any change to the file produces a completely different value.
No account, no limits, no file sent anywhere.
Add the file to the tool above. The MD5, SHA-1 and SHA-256 hashes appear instantly — compare them with the published values, free, no account.
SHA-256 is today's standard and what most publishers publish. MD5 and SHA-1 still appear on older download pages; they're fine for integrity checks but no longer secure against deliberate tampering.
That your copy is byte-for-byte identical to the original — no corruption in transit and no tampering. One differing character means the file changed.
No. The hashing runs entirely in your browser, so even a sensitive file never leaves your device.
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.
