Check a file fingerprint locally

Developers and security teams use File fingerprint when preparing a check, a local test or integration data.

Check a file fingerprint locally and get a clear value ready to copy or compare. Use it for free in your browser, with no account required.

How to use

Choose the fingerprint algorithm from SHA-256, SHA-384 or SHA-512.
Select the file whose fingerprint you want to check.
Run the calculation to get the hash value of the file.
Compare the result with the official fingerprint provided by the file source.

Example

A typical case is downloading a file and comparing its fingerprint with the value published by the author. If the two strings match, the file matches the expected version. If not, do not use it without further verification.

Limits and formats

The tool does not prove that a file is safe; it only shows whether its content matches a fingerprint.
It does not verify digital signatures or certificates.
The calculation may take time on a very large file.
Use the same algorithm as the one used for the reference fingerprint.

Where processing happens

The file is read and processed directly in your browser. It is not sent to an external service and does not leave your device. You can check a fingerprint even for a sensitive document.

Frequently asked questions

What is the difference between SHA-256, SHA-384 and SHA-512?

These algorithms produce fingerprints of different lengths. SHA-256 is common, while SHA-384 and SHA-512 offer longer variants. The choice depends on the reference fingerprint you need to compare.

Can I check a large file?

Yes, but the calculation may take several seconds depending on the file size and your device power. Keep the tab open during the operation and avoid starting several calculations at once.

Does the result guarantee integrity?

Matching fingerprints are a good sign that the content is the same. It does not by itself prove the origin of the file. For a complete check, also use a digital signature or an official source.
