About this tool

Compute MD5, SHA-1, and SHA-256 checksums for any file to verify integrity and detect changes. Calculations run locally via the Web Crypto API, so your file is never uploaded.

Verifying that a downloaded file is intact normally means reaching for command-line tools. This generator hashes any file in your browser using the Web Crypto API and gives you the MD5, SHA-1, and SHA-256 digests. It's a quick, private way to check file integrity or compare two copies.

Why use it

Fast, accurate, and private hashing with no uploads — ideal for developers, QA, and anyone verifying downloads or backups.

How it works

Select the file to hash.
Choose the algorithm or algorithms you need.
Copy the generated checksum or checksums.

Frequently asked questions

Which algorithms are supported?

MD5, SHA-1, and SHA-256.

What is a file hash used for?

To verify a file hasn't changed or been corrupted, and to compare two copies for equality.
