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.

Three clear moves

How to use File Hash Generator

  1. 01

    Add a file or text

    Choose the local content for which you need a checksum.

  2. 02

    Select an algorithm

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

  3. 03

    Copy and compare

    Copy the hexadecimal result and compare it character for character.

Good fits

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.

Know before processing

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.

Better output

Practical tips

01

Compare hashes from a trusted source when checking a download.

02

Use the same algorithm on both sides of the comparison.

03

Remember that even one changed byte creates a different digest.

Straight answers

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.
