File Checksum

Verify file integrity by generating MD5, SHA-1, and SHA-256 hashes locally.

Select File to Hash

Works with any file type. Processing is locally done in RAM.

What is a Checksum?

A checksum is a unique digital fingerprint of a file. If even a single byte of the file is changed, the checksum will look completely different, making it perfect for verifying downloads.

Local Privacy

Unlike online hash checkers, we process your file locally on your machine. Your file is never sent to any server, keeping your data secure and private.
