What Is a SHA-256 File Hash?

The SHA-256 File Hash tool computes the SHA-256 checksum of any file directly in your browser. This is commonly used to verify file integrity, confirm that a download matches its published checksum, and detect accidental corruption during transfer. All processing happens locally in your browser, so your files never leave your device.

How to Use This SHA-256 File Hash

1
Select FileClick 'Choose a file' and pick the file you want to hash.
2
Automatic HashingThe tool reads the file and computes its 64-character SHA-256 digest immediately.
3
Copy ResultClick the copy button to save the checksum for verification.

Frequently Asked Questions

No. The file is read and hashed entirely in your browser using the Web Crypto API. Your data never leaves your computer.

Checksums let you verify that a file has not been corrupted or tampered with. If the computed hash matches the one published by the provider, the file is almost certainly intact.

Yes. The file is streamed into the browser's crypto digest in chunks, so even large files can be hashed reliably, though very large files may take a moment.
