File Hash Checker
Calculate and verify MD5, SHA-1, SHA-256, SHA-384 and SHA-512 hashes directly in your browser without uploading your files to a server.
How to Use
Drag and drop any local file into the drop zone or click browse to select a file.
Watch real-time progress as MD5, SHA-1, SHA-256, SHA-384, and SHA-512 digests are calculated in parallel.
Optionally paste an expected checksum into the verification box to compare hashes automatically.
Copy individual hashes, copy all checksums to clipboard, or download a structured checksum report.
Why Use File Hash Checker?
100% Client-Side Privacy
Files are read locally via FileReader and Web Crypto APIs. No file bytes are ever uploaded or transmitted.
5 Cryptographic Algorithms
Calculates MD5, SHA-1, SHA-256, SHA-384, and SHA-512 simultaneously.
Instant Integrity Verification
Paste any vendor checksum to automatically verify if the file has been modified or corrupted.
Supports Large Files
Optimized memory handling with cancellable progress indicators for smooth operation.
About This Tool
The File Hash Checker enables users and security professionals to calculate cryptographic digests (MD5, SHA-1, SHA-256, SHA-384, SHA-512) for any local file. By leveraging the browser-native Web Crypto API, all hash computations execute on your CPU without uploading file contents.
