About the File Hash Checker
Verify that a download is genuine and undamaged: get the MD5, SHA-1, SHA-256 and SHA-512 hashes of any file, of any size, and compare them with the checksum published by the provider.
Key features
- MD5, SHA-1, SHA-256 and SHA-512 at once
- Files of any size, read in chunks
- Compare with an expected checksum
- Clear match or no-match result
- Copy any hash
- Files never leave your device
Verify downloads and files
Drop a file to calculate its checksums, then paste the hash from the download page. If they match, your copy is identical to the original, byte for byte.
Known example
The text hello world (11 bytes, no newline) has these hashes:

Hash algorithms compared
| Algorithm | Length | Security today |
|---|---|---|
| MD5 | 128 bits (32 hex) | Broken for security; OK for spotting corruption |
| SHA-1 | 160 bits (40 hex) | Broken for security; OK for spotting corruption |
| SHA-256 | 256 bits (64 hex) | Secure, the most widely used |
| SHA-512 | 512 bits (128 hex) | Secure |

How to use the File Hash Checker
- Drop a file onto the box, or click to choose one.
- MD5, SHA-1, SHA-256 and SHA-512 hashes are calculated in your browser.
- Paste the checksum from the download page to compare.
- A green match means the file is exactly the original.
