Create a checksum

File Hash Generator

Choose a secure hash algorithm, add a file or text, and copy the hexadecimal checksum. Compare it with a trusted published value when verifying a file.

Private by default

Processing stays in your browser. Your file is not sent anywhere by this tool.

Use the tool

Add your file or text below, adjust the options if needed, then download the result.

Loading the local processor…

You can add

Any local file, UTF-8 text

You will get

SHA-256, SHA-384, SHA-512, Hexadecimal checksum

How to use File Hash Generator

  1. 1

    Add a file or text

    Choose the local content for which you need a checksum.

  2. 2

    Select an algorithm

    Generate a SHA-256, SHA-384, or SHA-512 digest.

  3. 3

    Copy and compare

    Copy the hexadecimal result and compare it character for character.

When this tool is useful

  • Compare a downloaded file with a published checksum.
  • Confirm two local copies contain the same bytes.
  • Generate a reproducible digest for a text fixture.

Browser and format limits

  • A matching hash supports integrity checking but does not identify who published a file.
  • Different text encoding or line endings produce a different checksum.
  • Large files can take longer to read into browser memory.

Practical tips

TIP 1

Compare hashes from a trusted source when checking a download.

TIP 2

Use the same algorithm on both sides of the comparison.

TIP 3

Remember that even one changed byte creates a different digest.

File Hash Generator questions

What does a file hash tell me?

It provides a reproducible digest of the file bytes, which is useful for detecting whether content changed.

Which SHA option should I use?

Use the algorithm specified by the checksum you are comparing. SHA-256 is common for general integrity checks.

Does a matching hash prove a file is safe?

No. It shows the bytes match the compared value, but safety also depends on trusting the source of that value and file.
