File Hash Calculator A tool for verifying file integrity. It uses a specific mathematical algorithm (like MD5 or SHA-256) to convert files of any size into a unique fixed-length string (hash value or checksum).

Core Features：

• Multiple Algorithm Support: Supports calculating the most mainstream hash algorithms, including MD5, SHA-1, SHA-256, and SHA-512.
• Complete Security & Privacy: All file reading and hash calculations are fully completed locally in your browser. Your file data is never uploaded to our servers, ensuring absolute security.
