CHECK A FILE CHECKSUM
Calculate a repeatable cryptographic fingerprint for any local file. Compare the result with a checksum published by a trusted source.
HOW TO USE IT
- 01Choose the file you want to verify.
- 02Select SHA-256, SHA-384, or SHA-512.
- 03Wait for the hexadecimal hash to appear.
- 04Copy it and compare every character with the trusted reference.
WHAT A MATCH MEANS
A matching checksum supports the conclusion that your copy has the same bytes as the reference file. Even a one-byte change produces a different result.
NOT A MALWARE SCAN
A hash does not inspect a file for malicious behavior and cannot prove that the publisher is trustworthy. Obtain reference hashes from an authoritative source.
FREQUENTLY ASKED QUESTIONS
Which algorithm should I choose?
Use the algorithm named by the file publisher. SHA-256 is a common modern default when a choice is available.
Is the selected file uploaded?
No. The browser's cryptographic API reads it locally.
Why does my hash not match?
The file may be incomplete, modified, a different version, or compared with the wrong algorithm.
