Usage

Features

This tool computes file hash values (Hash) with support for multiple common algorithms. All calculations run locally in the browser; files are never uploaded, ensuring data privacy.

Supported Algorithms

MD5: classic 128-bit hash algorithm (via SparkMD5). SHA-1: 160-bit hash algorithm. SHA-256: 256-bit hash algorithm with stronger security. SHA-512: 512-bit hash algorithm.

Steps

1. Click the upload area or drag a file into it; 2. Select the hash algorithms to compute (all selected by default); 3. Click "Calculate"; 4. Copy the corresponding hash value when done. Computing SHA on large files (>500MB) may crash the browser; MD5 is recommended.
