How to use the Hash generator (MD5, SHA-256…)

Can a hash be reversed?

No. A hash is a fingerprint, not encryption — you cannot get the original text back from it.

Is the file uploaded?

No. Files up to 2 GB are hashed on your device.

Is my data sent anywhere?

No. Everything is calculated in your browser on your own device — nothing you type or upload is sent to a server.
