File Hash Checker
File Hash Checker computes the SHA-1, SHA-256, SHA-384, or SHA-512 hash of a file right in your browser using WebCrypto, and lets you verify it against an expected checksum. It is useful for confirming a downloaded file matches its published checksum without uploading the file anywhere.

About this tool
What Is File Hash Checker? File Hash Checker File Hash Checker is a browser-based tool for compute the SHA-1, SHA-256, SHA-384, or SHA-512 hash of a file in-browser and verify it against an expected checksum This guide explains what the tool does, how it works, and how to use it. How It Works The tool applies the operation shown in its interface: compute the SHA-1, SHA-256, SHA-384, or SHA-512 hash of a file in-browser and verify it against an expected checksum. Results depend on the input data and content type. How to Use It Open the tool and provide the required file or data. Choose the options that fit your needs. Review the result, then download or copy it. Important Notes Actual results depend on the content of the input and file type. Review the output before final use.

The tool computes SHA-1, SHA-256, SHA-384, and SHA-512 using the browser’s WebCrypto API. Does the file get uploaded anywhere? No. Hashing is done entirely in the browser with WebCrypto, so the file never leaves your device.
