How to calculate a file hash in your browser

The File Hash Tool calculates SHA checksums for local files without uploading them. Pick a file, choose the algorithm you need, then copy the resulting digest.

File hash examples

Compare a downloaded installer against a published SHA-256
Generate a SHA-512 digest for long-term archive verification

How to use this file hash tool

Select one file with drag and drop or the file picker.
Choose SHA-256, SHA-512, SHA-384, or SHA-1 depending on the checksum you need to compare.
Click Calculate hash, then copy the lowercase hex digest when it is ready.

File hash FAQ

Does the file leave my device?

No. The file is read and hashed locally in your browser. This site does not upload or store the file.

Why is MD5 not available?

MD5 is broken for security-sensitive use and unreliable for modern integrity verification. This tool focuses on SHA algorithms commonly used for release checks.
