File Hash Calculator
/file-hashCompute MD5, SHA-1, SHA-256, and SHA-512 hashes of any file. Verify downloads and detect corruption.
Downloading a file from the internet is only trustworthy if you can verify its checksum. This calculator computes MD5, SHA-1, SHA-256, and SHA-512 hashes of any file you choose. Comparing the result against the published hash detects corruption and tampering. Hashing runs locally, so the file never leaves your device.

FAQ
Frequently asked questions
Everything you need to know about file hash calculator.
Which algorithms are available?
MD5, SHA-1, SHA-256, and SHA-512 are available, all computed locally with the Web Crypto API in your browser.
Are large files supported?
Yes. Files are streamed in chunks, so multi gigabyte files hash without loading the entire file into memory.
What are hashes used for?
Hashes verify that a download matches the published digest, detect corruption after transfer, and confirm two files are byte identical.
Why are multiple algorithms offered?
Different sources publish different digests, and some use stronger algorithms. You can compare against MD5, SHA-1, SHA-256, or SHA-512 as needed.
Is my file uploaded?
No. Hashing runs entirely in your browser using the Web Crypto API, so the file never leaves your device.
Should I still use MD5 or SHA-1?
Both are broken for collision resistance, but they remain useful for checksums and legacy verification when the digest was published in that algorithm.
