What is a file checksum?
A file checksum is a unique hash value generated from a file’s contents. Even a tiny change in the file will produce a different checksum. This makes checksums useful for verifying downloads, detecting corruption, and comparing whether two files are exactly the same.
Why use this checksum generator?
This tool runs entirely in your browser, so your files are not uploaded to a server. That makes it fast, private, and practical for checking downloads, installers, documents, archives, and media files.
You can generate multiple secure hash formats and copy them for later comparison. It is useful for developers, IT teams, security checks, software downloads, and anyone who wants to confirm file integrity.
Supported checksum algorithms
This tool supports SHA-1, SHA-256, SHA-384, and SHA-512 using the browser’s Web Crypto API. These are widely supported and reliable for integrity verification. For compatibility reasons, MD5 is not generated in this browser-only version.
Common use cases
- • Verify downloaded software and installation files
- • Compare two files without opening them manually
- • Detect accidental file corruption during transfer
- • Confirm backup and archive integrity
- • Generate reference hashes for documents or assets
