Calculate MD5, SHA-1, SHA-256 hash values for files and verify integrity with checksum comparison.
Drag and drop files or click the "Select Files" button to add files.
MD5, SHA-1, and SHA-256 hash values are automatically calculated for each file.
Optionally enter an expected hash value to verify file integrity.

File Hash Checker is an online tool that calculates cryptographic hash values from files. It supports three algorithms: MD5, SHA-1, and SHA-256, and can be used for file integrity verification and tamper detection of downloaded files. All processing happens entirely in your browser, and files are never sent to any server.
No, all processing happens entirely in your browser. Calculations are performed locally using the Web Crypto API, and your files are never sent to any server.
It depends on your browser's memory, but generally files up to several hundred MB can be processed. Very large files may take longer to process.
Paste the expected hash value in the "Checksum Verification" field. It will automatically compare with the calculated hash values. Matches are shown in green, mismatches in red.
SHA-256 is recommended for security purposes. MD5 or SHA-1 may be needed for compatibility with existing systems, but they are vulnerable to collision attacks.
