File Hash / Checksum

Compute file checksums using SHA-256, MD5, SHA-1, or SHA-512. Everything runs locally in your browser. Files never leave your device.

Before you start

Upload

Upload any file type and choose the checksum algorithm.

Result

Copy the resulting hex digest for integrity checks or file comparison.

Local processing

Processing runs in your browser session. Files are not uploaded by default.

Limitations

Checksums verify integrity but do not encrypt files. SHA-256 is recommended for modern workflows.
