Generate MD5, SHA-1, SHA-256, and SHA-512 cryptographic hashes for any file in your browser. Files are never uploaded — all processing is local.
Open File Hash Generator → free, no sign-inVerifying that a downloaded file hasn't been tampered with — or checking that two copies of a file are genuinely identical — requires computing a cryptographic hash. The File Hash Generator calculates MD5, SHA-1, SHA-256, and SHA-512 hashes for any file, entirely in the browser. Your file never leaves your device.
Developers verifying file integrity after downloads, security professionals checking that a binary hasn't been modified, system administrators comparing file versions, or anyone who needs to verify a checksum against a published hash.
No tutorials. No learning curve. Open it and get started.
No server uploads. All four major hash algorithms are computed simultaneously — you get MD5, SHA-1, SHA-256, and SHA-512 in one step.
Completely free. No trial period. No premium tier for basic functionality. No account required. Use it as often as you need.
One job, done well. File Hash Generator was built to solve a specific problem cleanly. No feature bloat, no ads, no distractions.
What is a file hash used for?
To verify a file hasn't been modified or corrupted — compare the computed hash against a published expected hash.
Which hash algorithm should I use?
SHA-256 is the current standard for file integrity. MD5 and SHA-1 are considered cryptographically weak but are still used for checksums.
Is my file uploaded anywhere?
No — hashing runs entirely in your browser using the Web Crypto API.
Can I hash a large file?
Yes — there's no file size limit imposed by the tool (though very large files will take longer).
Why do different tools give different MD5s for the same file?
They shouldn't — if hashes differ, the files are different.
Free. Instant. No sign-in. Open it and get the job done.
