Hash Generator

Calculate checksums of text or files to verify downloads and compare data. Files are hashed in chunks locally, so even large ISOs work without uploading.

  • Runs locally in your browser

Your files are processed on this device and are never uploaded to a server.

How to use the Hash Generator

  1. 1

    Type text or choose a file.

  2. 2

    All hashes are calculated at once.

  3. 3

    Copy a hash or paste an expected value to compare.

Which hash to use

Use SHA-256 to verify downloads. MD5 and SHA-1 are fine for detecting accidental corruption but are broken for security purposes. Never use any of these alone to store passwords.

Frequently asked questions

Is my data sent to a server?

No. Everything runs in your browser as you type. Nothing is uploaded or logged, so it is safe to paste API responses, tokens and private text.
